Vehicle Height
1. Check the tire for proper inflation.
2. Measure ‘A’ from the center of the lower arm rear mounting
bolt end to the ground.
3. Measure ‘B’ from the center of the steering knuckle shaft to
the ground.
4. If the difference between ‘A’ and ‘B’ is not within specification,
adjust vehicle height using torsion bar height control bolt.

Notice
Before wheel alignment, adjust vehicle height first.

Removal & Installation Procedure
1. Inspection of tire
Check tread area for tread surface, crack, damage by nail
in or stones. Replace or repair if necessary.
lReplace the tire if tread-wear indicator of the tread
grooves appears where marked ' '
.
l
The wear limit of snow tire is the same as normal tire
(1.6mm) and indicator location is marked '
¯'.
Limit1.6mm
Standard2.66mm
Standard2.03mm 2. Wear limit.
3. Runout measurement.
lExcessive runout of tires and wheels can cause the
abnormal wear of tire. Using a dial indicator, measure
wheel and tire runout.
lMeasure radial runout at the rim flange and center of
the tire tread area.
lMeasure lateral runout at the tire bead area of the wheel
and tire sidewall.
Notice
If runout is excessive, replace the tire or wheel.
