Commonly affects rocker panels, cab corners, fender wells, tailgate, floorboards, and frame rails, particularly in regions exposed to road salt. This compromises structural integrity and can be costly to repair.
Aging wiring harnesses become brittle, leading to poor grounds, failing switches (power windows, locks, lights), and intermittent instrument cluster malfunctions. Alternators and starters also fail with age.
Ball joints, tie rods, control arm bushings, leaf springs, and the steering gearbox develop significant play, leading to loose steering, poor handling, and accelerated tire wear. Shocks are typically worn out.
