Minor Body and Structure

Sill (Rocker Panel) Corrosion

Symptoms

The outer sill skin softens and crumbles. Door alignment changes as the inner sill structure weakens. The car may creak or flex over bumps.

Cause

Box-section sills trap water when drain holes block. Corrosion works from inside, so the damage is often worse than it appears from outside.

Fix

  1. 1 Full sill replacement -
  2. 2 inner and outer sections. Some repair panels are available; others require fabrication. Cost: $1,000--2,500 per side
Cost mentioned in fix
Cost: $1,000
