Symptoms
Bouncing after bumps, wallowing on the road, or leaking or rusted shocks. This is common on campers carrying more than the original spec.
The fix, step by step
- Support the chassis on stands, then unbolt and remove each shock, keeping track of spacers and bushings.
- Fit new shocks with new bushings.
- For a heavy camper, match the springs to the load too: Hellgeth makes 435-specific coils for heavy rear-axle loads.
Tools & part numbers
- Jack and stands
- metric sockets
- penetrating oil
