A vehicle pulls or leads in one direction during
hard acceleration. A vehicle pulls or leads in the other direction during
deceleration.
The following factors may cause torque steer to be more apparent on
a particular vehicle:
• | A slightly smaller diameter tire on the right front increases
a right torque lead. Inspect the front tires for differences in the brand,
the construction, or the size. If the tires appear to be similar, change
the front tires from side-to-side and retest the vehicle. Tire and wheel
assemblies have the most significant effect on torque steer correction. |
• | A large difference in the right and left front tire pressure |
• | Left-to-right differences in the front view axle angle may cause
significant steering pull in a vehicle. The pull will be to the side with
the most downward sloping axle from the differential to the wheels. Axles
typically slope downward from the differential. The slope of the transaxle
pan to level ground may be used as an indication of bias axle angles. The
side with the higher transaxle pan (shown on the left side of the illustration)
has the most downward sloping axle angle. |
