Symptoms
A shaking steering wheel around 45–50 mph, play when a raised front wheel is rocked top to bottom with the brakes held, or oil and grease weeping from the swivel balls.
The fix, step by step
- Follow BigJimny's death-wobble order.
- Check tire balance first, then rock each front wheel with an assistant holding the brakes: play that remains points to the kingpin bearings, play that disappears points to the wheel bearings.
- Check tie-rod ends, radius-arm bushes and the hub face behind the brake disc for rust.
- If the kingpins are worn, rebuild them with Koyo bearings, a new halfshaft seal and waterproof grease.
