Symptoms
Wet or crunchy carpet, holes under the mats, soft rockers, bubbling paint low on the quarters and around the fuel tank.
The fix, step by step
- Pull the seats and carpet and wire-brush everything to see how far it goes.
- Cut back to clean metal and weld in floor sections, rockers and lower-quarter patches, then seam-seal, prime and undercoat.
- Panels sold for the four-door Wagoneer won't all fit a two-door Cherokee, so test-fit before cutting.
