- Also check the hub-face measurement, spring/U-bolt arrangement, wheel offset and mudguard clearance.
Signs Your Trailer Axle Needs Replacing
- Replacement or professional inspection is recommended if the axle has significant corrosion, bending, damaged bearing journals, worn spindle threads, abnormal tyre wear, wheel misalignment or repeated wheel-bearing failures.
- When fitting a new axle, inspect the wheel bearings, seals, hubs, springs, U-bolts, spring plates and suspension hardware at the same time.
