Symptoms
Grease and oil weeping from the swivel seals, play at the top and bottom of the wheel, or a rumbling front wheel bearing.
The fix, step by step
- The 160 uses kingpin swivel hubs.
- A complete rebuild kit for MQ 160s (Basco Wholesale, via Bunnings Marketplace) contains four wheel bearings, four kingpin bearings, two needle-roller bearings, two 65-88-11/16.5 oil seals and a swivel gasket and seal kit.
- Jack and support the axle, remove the hub cap or free-wheeling hub (if fitted), the wheel bearings and the stub axle, and draw out the axle shaft.
- Unbolt the kingpin caps, keeping each shim pack with its cap, and drop the swivel housing off the kingpin bearings.
- Replace the bearings, inner seal and swivel wiper seal, then refit with the original shims.
- Set kingpin preload and wheel-bearing preload to your workshop manual, then refill or regrease as the manual specifies.
