23.Tire Check and Rotation

A: INSPECTION

1) When the tread has worn to less than 1.6 mm (0.063 in) or the tread wear indicator appears across the

tread, replace the tire. (Replace the right and left tire as a set.)

2) If the tire appears to be worn unevenly, adjust the wheel alignment.

3) Next, make a tire rotation between front and rear as shown in the figure, make sure tires are worn evenly.

• When the direction of tire rotation is not specified

24.Steering System (Power Steering)

A: INSPECTION

1. STEERING WHEEL

1) Set the steering wheel in a straight-ahead position, and check the wheel spokes to make sure they are cor-

rectly set in their specified positions.

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 — 30 mm (0 — 1.8 in)

Move the steering wheel vertically 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.

(1) Steering force:

The effort required for steering should be smooth and even at all points, and should not vary.

(2) Pulled to one side:

Steering wheel should not be pulled to one side while driving on a level surface.

(3) Wheel runout:

Steering wheel should not show any sign of runout.

(4) Return status:

Steering wheel should return to its original position after it has been turned and then released.

2. STEERING SHAFT JOINT

If steering wheel play is excessive, disconnect the universal joint of steering shaft and then check the play

where the joints cross and yawing torque. Also, check the seal for damage or serrations for wear. If the joint

is loose, retighten the mounting bolts to the specified torque.
Tightening torque:

35 N·m (3.6 kgf-m, 25.8 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.

3) With the vehicle stopped on a level surface, quickly turn the steering wheel to the left and right.

While steering wheel is being rotated, check the gear backlash. If any noise is noticed, adjust the gear back-

lash.

4. TIE-ROD

1) Check the tie-rod and tie-rod end for deformation, cracks and other damage.
