Sill and Jacking Point Corrosion
Symptoms
The sills (rocker panels) and integrated jacking points soften and crumble. The jacking point collapses when weight is applied.
Cause
Box-section sills trap moisture and rust from inside. The jacking point reinforcement corrodes similarly. Road spray from below and water entry from above (through door seal failures) accelerate the process.
Fix
Sill replacement panels are available.
The entire sill section must be cut out and new metal welded in.
This is a significant panel-beating job that affects body rigidity.
Cost: $1,000-2,500 per side.
