What can fail
Rust on the rear cross member can cause the spare tire stored under the truck bed to fall off, creating a road hazard. Corrosion can also damage brake lines and the proportioning valve, reducing braking power.
What the fix does
Dealers will inspect the rear cross member and brake components. They will replace corroded parts or apply corrosion protection coating if replacement isn't needed.
