Critical Body

Inner Guard and Chassis Rail Rust

Symptoms

Hidden rust in the front inner guards and the chassis rails where they pass through the engine bay.

Cause

Road spray and mud collect in the inner guard area, sitting against the metal for months or years. The engine bay heat cycling accelerates corrosion once it starts.

Fix

Clean out the inner guards, cut away rusted metal, fabricate and weld new sections.

Budget $1,500-4,000 per side.

This is hidden structural work that must be done properly.
