Symptoms
Greasy gunk on the front swivel balls, steering that wanders, or play when you rock the top of the tyre with the wheel off the ground. On a GQ the swivel and CV bearings run in grease. If diff oil is leaking out of the swivels, the inner axle seal has failed.
The fix, step by step
- Jack up and support the front, then remove the wheel, free-wheeling hub, CV circlip, brake caliper (hang it up, don't let it dangle), wheel bearings and hub.
- Unbolt the swivel housing from the axle, pull the CV and axle shaft, and replace the inner axle seal while it's out.
- Replace the upper and lower kingpin bearings and the swivel cap seals (owners often damage the caps on removal), then reassemble.
- Set kingpin preload with the factory shims and fit new wiper seals on the swivel ball.
- Repack with fresh grease and, if any diff oil was lost, top up the front diff.
