Camber measures tire lean. To check camber, make sure the vehicle is parked on level ground. If not, factor the ground slope into the camber reading. Then place a straight edge across the wheel use the inner lip if the outer is nicked or uneven and use an angle finder to reveal camber. Is it necessary to change it? What are the signs of bad transmission fluid? There are a few ways that you can test to see if your tires still have traction.
If you can see the top of his head, your tire treads are running dangerously low. 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.
To that end, I made some helpful illustrations:. Show the supply chain who's boss Get a head start on your holiday shopping at Amazon, Target, Best Buy, and more. This is annoying and even dangerous. To illustrate how this works, let me show you the measure of how parallel or not the wheels are, as viewed from above, in relationship to each other and to the body of the car.
Toe-in results from the leading edge of the wheels and tires being closer to each other than the trailing edge. Toe-out is the opposite.
This is the measure of the vertical plane of the wheel as it is perpendicular to the ground. Positive camber means the top of the wheel and tires are leaning out. Negative camber means the wheels are leaning inward. Typically, you want This is the rotation of the wheel assembly along its own axis, typically being the angle between vertical and the lean of the strut assembly.
Too much, however, and it begins to affect camber in turns.
