avoid this situation, rear camber and toe should be adjusted before the front when performing a four wheel alignment. After the rear is set, center
the steering wheel, lock it in place, then adjust the front camber, caster, and toe (if applicable).
3. Tires - Tires can have significant effect on vehicle drift or pull. Arranging tires on a vehicle according to StraightTrak can greatly improve or
eliminate a vehicle drift or pull. Tires contribute to vehicle drift or pull in the following ways:
a. Ply steer - Ply steer is an inherent characteristic in a tire which results in a lateral force as the tire rolls. Rotating the tires may aid in cancelling
out the effects of ply steer.
b. Conicity - Tire conicity refers to the shape of the tire, and how cone-shaped it is. This can influence vehicle drift or pull. Conicity can be present
in a new tire due to manufacturing, or in a used tire due to camber wear. Rotating tires may aid in reducing vehicle drift or pull due to tire
conicity.
4. Weight - The amount of weight and where the weight is placed alters a vehicle's alignment angles, thus changing the drift/pull tendency. It is
important to consider this when diagnosing a vehicle drift or pull. The best way to eliminate the effects of weight is to align the vehicle with the
customer's typical carrying load.
5. Road Crown - Every vehicle will have a tendency to follow road crown towards the low side of the crown. Be sure to conduct test drives on a road
that is as flat as possible to eliminate the possibility of road crown sensitivity.
6. Brake Drag - If one side of a vehicle's brakes are dragging, the vehicle can have a drift or pull tendency towards that side. Inspect the brake system to
ensure brake drag is kept to a minimum on all four wheels.
7. Cross Winds - Cross winds can push a vehicle towards one side of the road. It is important to conduct road testing by driving a vehicle in opposite
directions to verify the effects of cross winds.
