Troubleshooting
Suspension unit making noise
Check that all mounting bolts are securely tightened. Inspect for any loose components or damage to the suspension arm or axle.
Trailer handling feels unstable
Verify the load is within the 550kg per pair limit. Ensure wheel bearings are properly greased and the hub is correctly fitted and secured.
Rust appearing on the unit
While galvanised, prolonged exposure to harsh conditions may cause minor surface rust. Clean affected areas and consider applying a protective coating suitable for galvanised metal.
Hub does not fit onto stub axle
Confirm the hub is designed for a 1" stub axle. Ensure there are no obstructions or damage on the stub axle or inside the hub's bearing race.
