Rear Wheel Bearing Wear
Symptoms
Humming or grinding noise from the rear, increasing with speed. The noise may change tone when turning (loading one side more than the other).
Cause
The rear wheel bearings on Z-cars are a known wear item. They are tapered roller bearings that require periodic adjustment and eventually wear beyond the adjustment range.
Fix
Replace the rear wheel bearings.
This requires a press to remove and install the bearings.
The half-shaft must be removed, the bearing pressed off, and a new bearing pressed on.
Cost: $100-200 per side in parts.
Not a particularly difficult job but requires access to a press.
