Symptoms
Flaking or perforated steel at the rear crossmember, soft outriggers, fresh underseal hiding something.
The fix, step by step
- Clean back to bare metal and assess.
- Outriggers and rear crossmembers are bolt-on or weld-in replacement sections; cut out the rotten section, fit the new one square to the frame and seam-weld it, then protect the inside of the box sections.
- If the main rails are thin as well, a galvanised replacement chassis is the permanent answer.
