Symptoms
Bubbling paint on the rockers ahead of the rear wheels, soft spots in the front floor under the carpet, water inside, or rust reaching the body-mount crossmembers.
The fix, step by step
- Strip the area back to clean metal and find out how far the rot really goes.
- Owners warn that it's usually worse than it looks.
- Cut out the rotten section, make or buy patch panels and weld them in, then seal, prime and undercoat.
- RamCharger Central members note that replacement rocker panels have been available.
- If the body-mount crossmembers are rotten, plan to lift the body or replace the mounts at the same time.
