Sills (Rocker Panels)
Symptoms
The sills rot, badly. All three sections, outer sill, inner sill, and the welded-in reinforcement, corrode together.
Cause
Water ingress, blocked drain holes, and no factory protection. Once one section goes, the others follow.
Fix
This is a welding job.
Repair sections are available and not expensive, but labour will cost you.
If you can't weld, budget accordingly.
Check the underside of the front fenders above the sills, that rots too.
