Helpful hints to determine cause of vehicle pulling:
The direction of lateral force from tire conicity becomes reversed when the left and
right tires are switched. Therefore, if the pulling direction changes when the tires are
switched, it can be concluded that vehicle pulling is caused by tire conicity.
ORIGINAL TIRE POSITIONS TIRES SWITCHED
The Vehicle is Pulled to the Right by
the Lateral Force Exerted to the Right.The Direction of the Tires Which Exerted Lateral
Force to the Right has Been Changed, so the Tires

If the pulling direction does not change after the front tires are switched, the cause of
vehicle pulling is not tire conicity. In this case, the likely cause is a front wheel
alignment condition.
3. Vehicle Pulling Caused by Wheel Alignment
When it is determined by troubleshooting that the vehicle pulling to one side is
caused by wheel alignment, perform repairs according to the following procedure.

STEP 3:
Adjust cross camber to eliminate vehicle pulling.
HINT:
If the tires are placed in the positions they were in during tire rotation when the least
amount of vehicle pulling occurred, wheel alignment can be performed with a minimal
amount of adjustment.
WHEN VEHICLE PULLS TO LEFTWHEN VEHICLE PULLS TO RIGHT
Increase right front camber and decrease left
front camber until vehicle pulling is eliminatedIncrease left front camber and decrease right
front camber until vehicle pulling is eliminated
NOTE:
Keep the cross camber within 1
or less.
Keep the camber of each wheel within specifications (+/±45' of center value).
If adjustment exceeds the specifications, uneven tire wear will result.
5. Camber Adjustment Method
NOTE:
After the camber has been adjusted,
inspect the toe±in.
NOTE:
The method of camber adjustment
differs for different models, so please
refer to the repair manual of the
vehicle involved. (This is a sample
from the RX 300 Repair Manual).
A. Remove the front wheels and
ABS speed sensor clamp.
B. Remove the two nuts on the lower
side of the shock absorber.
C. Coat the threads of the nuts with
engine oil.
D. Temporarily install the two nuts.
E. Adjust the camber by pushing or
pulling the lower side of the shock
absorber in the direction in which
the camber adjustment is
required.
F. Tighten the nuts.
