Signs Your Trailer Axle Needs Replacing
- Replace or professionally inspect the axle when there is bending, significant corrosion, damaged bearing journals, worn spindle threads, abnormal tyre wear, wheel misalignment or repeated wheel-bearing failure.
- When fitting a new axle, also inspect the bearings, seals, hubs, springs, U-bolts, spring plates and other suspension hardware.
