Signs Your Trailer Axle Needs Replacing

Replace or professionally inspect the axle if there is excessive corrosion, a bent axle beam, damaged bearing journals, damaged spindle threads, abnormal tyre wear, wheel alignment problems or repeated wheel-bearing failures.
When replacing an axle, inspect the wheel bearings, seals, hubs, springs, U-bolts, spring plates and suspension hardware.
