WHEEL BEARING DIAGNOSIS
This vehicle with non–serviceable bearings in the rear
wheels. If any fault is found with a wheel bearing, it must

Wheel Bearing Noise
A road test usually reveals excessive wheel bearing
noise. Wheel bearings emit a howling sound when loose
or damaged. Wheel bearing noise is present only when
the vehicle is moving. It is constant and unwavering and
increases with the speed of the vehicle. If the wheel
bearing noise cannot be positively diagnosed, or if the
origin of the noise cannot be determined, perform the
following test :
1. Raise and suitably support the vehicle.
2. Spin the wheels using your hand. Check for out–of–
round or out–of–balance tires, bent rims, or loose
wheel bearings.
3. Spin the rear wheels using a commercial wheel spin-
er.
4. If a noise can be heard from the passenger compart-
ment, replace the noisy wheel bearings. Refer to Sec-
tion 2D, Rear Suspension.
5. Lower the vehicle.
