WEAR ISSUE

1996 Jeep Cherokee

Tires and Wheels problem
1996 Jeep Cherokee 6 cyl Four Wheel Drive Automatic 140, 00 miles

the front driver side tire is approximately 40/1000 more wear than the front passenger side tire. The wear is even across the tire surface as measured in the tread recesses. What would cause this uneven wear from one side to the other

Hello,

Weak, sagging springs can cause a los of ride height that throws off wheel alignment. Coil and leaf springs sag with age, which can alter camber as well as caster alignment. Measuring ride height will tell you if the springs are still within specifications or not.

If ride height is below specifications, the springs need to be shimmed or replaced. If ride height is okay but camber is out of specifications and a tire shows heavy shoulder wear, a strut or steering knuckle may be bent. This type of damage can be found by having the Steering Axis Inclination (SAI) checked on an alignment machine.
