2. Lightly turn the steering wheel to the left and right to determine the point where front wheels start to move.
Measure the distance of the movement of steering wheel (periphery).
Steering wheel free play:
0 — 17 mm (0 — 0.67 in)
(1) | Steering wheel free play |
Move the steering wheel toward the shaft to check if there is play in the direction.
Play limit:
0.5 mm (0.020 in)
3. Drive the vehicle and check the following items.

(4) Return status:
Steering wheel should return to its original position after it has been turned and then released.
2. STEERING SHAFT JOINT
When the steering wheel free play is excessive, disconnect the universal joint of steering shaft and check it for any play and yawing torque (at the point of the crossing direction). Also inspect for any damage to sealing or worn serrations. If the joint is loose, retighten the mounting bolts to the specified torque. Universal Joint">
Tightening torque:
24 N·m (2.4 kgf-m, 17.4 ft-lb)
3. GEARBOX
1. Set the steering wheel in the straight position, then rotate it 90° in both the left and right directions.
While steering wheel is being rotated, check the looseness of the gearbox.
Tightening torque:
60 N·m (6.1 kgf-m, 44.3 ft-lb)
2. Check the boot for damage, cracks or deterioration.

Tightening torque:
27 N·m (2.75 kgf-m, 19.9 ft-lb)
3. Check the lock nut on the tie-rod end for tightness. If it is loose, retighten it to the specified torque.
Tightening torque:
85 N·m (8.7 kgf-m, 62.7 ft-lb)
5. GEARBOX BOOTS
Inspect both sides of the gearbox boot as follows, and correct the defects if necessary.
1. The (A) and (B) positions of the gearbox boot are fitted in (A) and (C) grooves of gearbox and the rod.
2. Clips are fitted onto the boot grooves to the positions (A) and (B) of the boot.
3. Check that there is no cracks or holes in the boot.
NOTE:
Rotate (B) position of gearbox boot against the torsion produced by the adjustment of toe-in etc. Apply grease to the groove (C).
