Signs the Trailer Spring Needs Replacing
- Replace the spring if there are cracked or broken leaves, severe corrosion, permanent flattening or sagging, worn eye bushes, damaged centre bolts, spreading or misaligned leaves, uneven trailer ride height or excessive suspension movement.
- On boat trailers, inspect the springs regularly for corrosion around the leaf contact points, centre bolt and spring eye, particularly after repeated saltwater immersion.
