Steering Wheel Play CheckS7RS0B6304024
• Check steering wheel for looseness or rattle by moving it in its shaft direction and lateral direction.
If found defective, repair or replace.
• Check steering wheel for play, holding vehicle in straight forward condition on the ground with engine
stopped.
If steering wheel play is not within specification,
inspect as follows and replace if found defective.
• Tie-rod end ball stud for wear (Ball stud should move when more than 0.2 N ⋅m (2 kg-cm, 0.44 lb-ft) torque is
applied.)
• Lower ball joint for wear
• Steering shaft joint for wear • Steering pinion or rack gear for wear or breakage
• Each part for looseness

Steering Force CheckS7RS0B6304025
1) Place vehicle on level road and set steering wheel at
straight-ahead position.
2) Check if tire inflation pressure is as specified referring to the tire placard.
3) Remove driver air bag (inflator) module referring to “Driver Air Bag (Inflator) Module Removal and
Installation in Section 8B”.
4) Start engine.
5) With engine idling, measure steering force by turning torque wrench.
Steering force
: Less than 6.4 N ⋅m (0.64 kgf-m, 4.6 lb-ft)
6) Install driver air bag (inflator) module referring to “Driver Air Bag (Inflator) Module Removal and
Installation in Section 8B”.
