INSPECTION

PROCEDURE

1. INSPECT TIRES

(a) Check the tires for wear and proper inflation pressure.

Cold Tire Inflation Pressure (Unloaded Vehicle):

Tire Size	Vehicle Model	Front kPa (kgf/cm2, psi)	Rear kPa (kgf/cm2, psi)
P265/70R17 113S	GRN280L-GKAGKA GRN285L-GKAGKA	220 (2.2, 32)	220 (2.2, 32)
P245/60R20 107H	GRN280L-GKAGKA GRN285L-GKAGKA	220 (2.2, 32)	220 (2.2, 32)

(b) Using a dial indicator, check the tire runout.

Standard tire runout:

3.0 mm (0.118 in.) or less

2. ROTATE TIRES

HINT:

Rotate the tires as shown in the illustration.

*b	P265/70R17 113S

(b) If necessary, check and adjust the on-the-car balance.

Standard Imbalance after Adjustment:

Tire Size	Wheel Size	Imbalance
P265/70R17	17 x 7J, 17 x 7.5J (Aluminum Wheel)	6.0 g (0.0132 lb) or less
17 x 7J, 17 x 7.5J (Steel Wheel)	12 g (0.0265 lb) or less
P245/60R20	20 x 7J (Aluminum Wheel)	6.0 g (0.0132 lb) or less

(Aluminum Wheel)

6.0 g (0.0132 lb) or less

17 x 7J, 17 x 7.5J

(Steel Wheel)

12 g (0.0265 lb) or less

P245/60R20

20 x 7J

(Aluminum Wheel)

6.0 g (0.0132 lb) or less

NOTICE:

The imbalance after adjustment value is the conversion value at the rim flange position.
Using a cleaning detergent, remove dirt, oil and water from the surface where the balance weight is to be adhered.
Do not touch the adhesive surface of the tape.
Attach a sticking type balance weight to the flat surface (A) shown in the illustration.
Width (A):

25 mm (0.984 in.)
Push the balance weight with your finger so that it securely adheres to the position.
Do not reuse the balance weight.

4. INSPECT FRONT AXLE HUB

(a) for 2WD:

Inspect the front axle hub (See page ).

(b) for 4WD:

Inspect the front axle hub (See page ).

5. INSPECT REAR AXLE SHAFT

(a) Inspect the rear axle shaft (See page ).
