Most people think that wheel alignment is best left to the professionals. This is true in many respects, but some alignment specs are easy to check yourself, and toe is one aspect of alignment that can be checked at home. This can come in handy after replacing steering or suspension components so that the vehicle won't be wildly out of adjustment for the trip to the alignment shop, or at the very least provide a better understanding of the alignment process.

Factors affecting wheel alignment
In theory, all four wheels should be perpendicular to the ground and parallel to each other. When the vehicle starts pulling to one side – or after a sharp impact with a curb – most drivers suspect that the wheels might be out of alignment. Irregular tire wear, vibration and odd handling characteristics are other clues.

The three factors that affect alignment are toe-in, camber and caster. The first two can easily be checked at home.

Toe-in
Car front tires are slightly pigeon-toed to intentionally place a very slight load on the wheel bearings. Typical toe-in specs vary from one-thirty-second to one-eighth-inch, depending on the vehicle. Check a service manual for your car's acceptable range.

The best tip-off to a toe problem is a saw-tooth wear pattern that's equal on both front tires. If the tread blocks point toward the frame, then toe-in is excessive; pointing outward indicates too much toe-out.

Toe-in spec-check and adjustment are shown in the accompanying photos. Although no specialized tools are necessary to check toe, companies such as Eastwood, JC Whitney and Harbor Freight sell tools specifically for this purpose.

Two things to remember when measuring and adjusting toe: First, true spec is measured midway up the tires. If the car's body makes this impractical, take the front and rear measurements one-quarter of the way up the tires, then double that to get the true toe as it would be in the center of the tires. Also, an off-center steering wheel can sometimes be corrected by adjusting one tie-rod more than the other. (Steering wheel position has no effect on your final alignment.)

Camber
Camber is the measurement of tire lean in degrees. If the top of the tire tilts inward, the vehicle has negative camber; outward lean is positive camber. Most newer vehicles have slightly negative camber to improve stability and handling.

Two indicators of camber problems are the vehicle pulling to one side (the one with more positive camber or possibly less air in the tire) and uneven tire wear across the tread. Camber is easy to check with an angle finder and a straight edge, ideally one that's the same length as the wheel diameter so that tire sidewall bulge doesn't interfere with the straight edge.

Many front-wheel-drive cars don't have camber adjustments, and out-of-spec camber here often indicates bent or worn parts. On vehicles that have adjustable camber, the job can involve adding shims between the control arms and frame and turning cam bolts. Many people prefer to let an alignment shop make these adjustments, particularly if their car has independent rear suspension.

Caster
Caster is the angle of steering pivot in degrees. Just as water-skiers lean backward for stability, most vehicles are designed with slight negative caster – the upper ball joint is to the rear of the lower ball joint (similar to the front wheels on a shopping cart).

A clue to caster problems is the vehicle pulling to one side (the one with less positive caster). Heavy steering and wheel hopping over bumps are signs of too much positive caster, and light steering but excessive wander are clues of too much negative caster. Aligning to spec usually involves repairing or replacing chassis parts, so the average motorist is probably better off leaving caster corrections to the pros.

Taking a few minutes to check your alignment will make your tires last longer and your vehicle handle better. Even if you choose to have a shop align the vehicle, you'll have a better idea of the problem – and knowledge normally equals power.

How to Do an Alignment on a Car

  1. How to Do an Alignment on a Car

Jessica Shea Choksey | Nov 09, 2020

Vehicle alignment refers to a mechanical procedure that adjusts the suspension to its proper configuration, correctly positioning the axles and wheels to allow the tires to make even contact with the road surface. It also ensures that a vehicle's wheels are "squared up" to one another.

A vehicle comes out of alignment gradually over time from treading over minor imperfections on the roadway. Or, it can happen suddenly from a single impact such as driving over a deep pothole or curb. Outside of such an occurrence, you should perform an alignment on your vehicle at regular intervals, as directed by the owner's manual.

When a suspension is out of alignment, the effects are evident. The vehicle may pull to one side, suffer from uneven tire tread wear, and feel less precise in terms of steering. If you disregard these symptoms, the alignment can progressively worsen and affect the vehicle's overall handling dynamics and safety.

Do-it-yourself tire fitting: manual tire changer -Articles

The change of seasons requires car owners to purchase two sets of tires. Off-season tires do not provide stability on an icy road and a comfortable ride in hot weather. The best solution is to purchase winter and summer tires. To save on service fees, you can use manual tire fitting when you need to change tires between seasons.

Insurance companies require timely replacement of tires. This ensures safety when moving in changing weather conditions. In the CASCO agreement, a separate clause states when to change tires to winter and vice versa. You can try to ensure high-quality tire fitting and comply with the requirements of the agreement on your own.

Timing for changing tires

It is important for drivers to distinguish between warm and cold seasons in order to understand when to change tires for summer or prepare a vehicle for operation in winter. Experts advise relying on weather data, using self-made tire fitting under such temperature conditions:

  • +5 ... +7 - to change tires to winter ones. Do-it-yourself tire fitting is necessary, because at night the temperature often drops to minus levels. Summer tires are not able to provide reliable grip on icy roads.
  • +10 and above - winter tires are no longer suitable for driving during the day at this temperature, since the transport is difficult to control.

In order to ensure safety while traveling, it is important to change the tires in time. I use a special tool and an understandable video about tire fitting with my own hands, you can try to cope with the work yourself.

Do-it-yourself tire fitting requires a special machine that will save you:

  • Means. You can use the device not only to change wheels on your vehicle. Large queues at workshops will help to find car customers.
  • Time. The driver does not need to sign up in advance and wait in line to change tires. Security can be ensured with your own hands.

How to assemble the machine?

Having decided to make a tire changer with their own hands, a manual tire changer is assembled first. You can find suitable models in stores, but you can assemble them yourself using available materials.

To do tire fitting with your own hands, the drawings are studied, and then everything you need is purchased. You can collect different types of devices. It is recommended to pay attention to functional and convenient models, which consist of several nodes:

  • Skeleton. This is the frame of the device. It is made of a profile pipe or two rectangular sections.
  • Vertical stand. It is fixed on the base, used as a platform for discs and for mounting a lever for removing tires.
  • Lever. Made from a pipe, used to remove the wheel.

It is recommended to choose high-quality rolled metal for the construction. Elements must withstand increased loads. The design must remain intact, not pose a threat to the master. Having decided to do the tire fitting with your own hands, the drawings for the manual tire changer are used as in the picture below.

Features of the workflow

To perform tire fitting with your own hands, hand tools are assembled in stages:

  • Choose a high-quality skeleton - strong metal structures that can withstand increased loads without deforming.
  • Observe a certain distance between the metal structure - from 700 mm. This ensures the stability of the machine during operation.
  • To strengthen the structure and ensure stability, the integrity of the pipes is arranged in parallel.
  • Install adjustable feet or castors, wheels. The latter make it easy to move and transport the product.
  • Create a frame with subsequent installation of a pipe with a diameter of 20-30 mm.
  • Mount the flange in front of the welding pipes at a height of 40–60 cm.
  • Fix the steel plate fastener used to further fix the lever.

Last install the lever, which consists of a paw and a shoulder. The first element will be required to remove the tire. Having assembled the structure, you can understand how to do tire fitting with your own hands. To do this, use the video guide below, photos and explanations of the masters.

Using a manual machine

In the absence of a special machine, it is almost impossible to dismantle or install rubber yourself. After assembling the device, you can start changing tires, for which you should learn how to do tire fitting. The process is carried out in several stages:

  • A wheel is installed on the base under the lever, from which the rubber is to be removed. You can only work with a stationary product.
  • Guide the paw so that it hits the butt of the disk with rubber.
  • Press the lever firmly so that the tire moves away from the disc. The process is repeated several times - from several sides, so that the tire moves away from the disk completely.

Further work can be done with a simple pry bar of great length (elements with a welded handle) to completely rid the disc of rubber. To do this, it is necessary to insert the mount with a narrow part under the rubber in order to bring it out of the rim.

Useful tips

Fix the wheels after installing it on a homemade machine using a special clamp.

  • Do not use excessive force when handling the mount. Otherwise, the edges of the rim may be damaged. In this case, it is difficult to install new tires.
  • Before work, it is recommended to lubricate the edges of the wheel with grease. The composition allows you to maintain the integrity of the product. After processing, the rubber becomes soft and pliable.
  • The soap solution used to lubricate the rim makes it easy and quick to install the rubber.
  • After installing a new tire, you need to check the product for gaps, deformation, loose fit to the disk.
  • For work, it is recommended to prepare a set of tools in advance. The kit includes sealing harnesses, a mount. All this is necessary for independent work.

It should be understood that the process of changing tires is quite laborious and complicated. It is necessary not only to assemble the machine with your own hands, but also to use it correctly, helping yourself with additional tools. It is not always possible to do such work, so you have to look for high-quality tire fitting.

How to find professionals

When deciding how to choose a tire service, it is recommended to pay attention to several points:

  • Cost. Often, even in one area there are several service stations, so the client has the opportunity to choose.
  • Appearance. For the sake of economy, it is not worth choosing an unknown office located in the nearest "pavilion".
  • Equipment. All the tools and equipment necessary for the work must be at the disposal of the masters. Devices must be serviceable and reliable. In good auto repair shops, the balancing device is mounted on a concrete base.

A punctured tire on a highway without a spare wheel is a classic situation that, in terms of the frequency of events, holds an honorable first place in the list of troubles for a motorist. The vast expanses of our Motherland add brightness and depth to this problem: there is not a single auto repair shop around, and if there is, then with a solid queue.

The most natural solution is to do the tire fitting yourself, that is, not to depend on anyone. The solution is excellent, but for its implementation you need to have some tools and skills. Where to gain skills and what tools to stock up, we read here and now.

Romance of the high road: tire fitting on the edge

Tire fitting on the track can be done with two mounting paddles and a special device to tear the tire off the rim. But it will turn out more convenient and civilized if you have a jack and a tow rope. And you will find them.

Drawing of a tire changer.

Therefore, we continue to work according to the following algorithm:

  1. Remove the wheel, clean it and put the nipple up.
  2. We release air from the wheel.
  3. We put the towing cable into the disc hole, put the jack close to the rim.
  4. We throw the cable on the jack bracket, fasten the ends of the cable to each other.
  5. It is necessary to rotate the handle so that the jack pulls the cable up, and the seat ring moves down until the tire separates from the rim.
  6. If the tube needs to be repaired or replaced, you need to lift the side of the tire onto the rim near the fitting, which we push inward and take out the tube under the tire.
  7. Remove the nipple, remove the air.
  8. Now we place it under the tire, but first we insert the fitting into the hole inside.
  9. Slightly pump up the inserted chamber, so far without a nipple.
  10. We make a flanging, insert the nipple into the fitting, fully inflate the chamber and put the wheel in its place.

All these ten points are easy to describe, but very difficult to do. And if the weather conditions leave much to be desired, then it becomes completely sad, you will remember such a tire fitting for a lifetime. The quality of such an installation will never be perfect.

It would be wiser to get some kind of mechanized device for independent tire fitting. There are many options for such devices - a wide variety of design solutions can be found on the network.

  • give complete independence from workshops;
  • give efficiency in repairs;
  • one of the main advantages is a serious financial savings.

We note right away that most of the mechanisms are designed for cars. Although no one bothers truck drivers to start building their own tire changer. On the topic " how to make a tire changer"There are a huge number of quite efficient videos on the net. They will be a great help.

Making a tire changer kit yourself

If you've made up your mind to become your own tire beading business, your best bet is to have a complete DIY tire changer in your garage. It can be made in the form of a kit: and a device for beating the board.

The bottom of the machine in the form of an H-shaped frame is made of a steel pipe with a rectangular section. The frame size is approximately 90 cm x 60 cm. At a distance of 30 cm from the edge to the lintel, a high round pipe is attached perpendicularly by welding.

Scheme of a tire changer.

The height of the pipe is about one and a half meters. It needs to be welded in the most stable way, so for the fortress it is better to weld “kerchiefs” of metal triangles with a thickness of at least 5 mm. A hub is welded to the round pipe - the middle part of the wheel.

At what height to weld the hub - we measure ourselves according to our height. It is necessary that the wheel lying on the hub is approximately at the level of your belt. The pipe must be at least 30 cm higher than the cylinder lying on the machine.

Bead breaker bracket must be welded below the hub. It is best cut out of a 5 mm thick steel sheet by drilling a hole in it for the bolt. The pipe for this machine assembly must be found wider, because it will fit a lever one and a half meters long.

It, in turn, is made of a steel pipe, and the tips are made of a steel 20 mm bar. Consider the length of the lever yourself, it will depend on the strength of your hands and the free space in the garage.
