Signs Your Trailer Axle Needs Replacing

  • Inspect or replace the axle if you find excessive corrosion, bending through the centre of the axle, damaged bearing journals, worn spindle threads, abnormal tyre wear, repeated wheel-bearing failures or incorrect wheel alignment.
  • When replacing the axle, inspect the wheel bearings, seals, hubs, springs, U-bolts, spring plates and suspension hardware at the same time.
