This causes a pull, lead or drift to the side of the vehicle that is least positive
What is caster
100
This can cause abnormal tire wear on both the outer edges of the tire or in the middle of the tire.
What is tire pressure
100
This toe adjustment can result in a pull, especially during acceleration
What is rear toe
100
This can cause tire wear on the inner edge of the tire when excessive
What is negative camber
100
If the caster on the right front of a vehicle is +3.5 degrees and the left side is +4.0 degrees, the vehicle will pull this way.
What is pull to the right
200
This causes a pull, lead or drift in the direction that is most positive
What is camber
200
This can cause excessive wear on either the outer or inner edge of the tire
What is camber
200
This should be the last adjustment made.
What is front toe
200
This can cause a pull, lead or drift to one direction or the other.
What is unequal camber
200
If the top of the steering axis is toward the rear or the vehicle it is called this
What is positive caster
300
This can cause a pull, lead or drift, abnormal tire wear and cannot be corrected with alignment adjustments
What is tire pressure
300
This does not directly result it tire wear, but in extreme positive situations along with frequent in town driving may cause inner edge wear.
What is caster
300
This will not cause a pull, but will excessively wear the tires
What is front toe
300
This can cause excessive wear on the outsides of the tires when excessive.
What is positive camber
300
This can be used to adjust caster as well as provide support for the lower control arm for forward/rearward forces
What is a strut rod/radius arm
400
The angle used on a "live" rear axle that can cause a pull, lead or drift, most noticeable under acceleration.
What is thrust angle
400
If this is improper by just 1/8 in. it will result in tire wear equivalent to dragging tire sideways 28 feet for every mile traveled.
What is toe
400
This is a common method for preventing the inner tie rod end from rotating in the outer tie rod end on rack and pinion steering.
What is a jam nut.
400
This is a common method of adjusting camber, often found on lower control arms. It consists of a threaded fastener fixed to a pair of washers with offset holes.
What is an eccentric bolt
400
The top of the steering axis it toward the front of the vehicle resulting in this.
What is negative caster
500
This can cause a pull lead or drift and can vary with road surface.
What is road crown?
500
This will typically cause extreme wear on tires only being slightly out of adjustment and will cause "feathered" wear, usually swept across most of the tread.
What is toe
500
This type of adjuster is commonly found on conventional steering linkages (Parallelogram, cross-steer, and haltenberger)
What is a threaded sleeve
500
This is a method of adjustment for camber that involves loosening bolts that hold the upper control arms in place and sliding them into place
What are shims
500
This is a method of adjustment that uses a threaded fastener that is fixed to washers that have offset holes. Adjustments are made by loosening the nut and rotating the fastener
