Power window motors on 1979-1993 Mustangs depend on small plastic bushings to keep the gear set aligned and moving freely. When those bushings wear out or crack, the motor binds, slows, or stops entirely. All Classic Parts supplies a direct-replacement bushing set that restores proper gear alignment and smooth window operation without sourcing worn takeoffs or hunting for discontinued OEM stock.
Positioned where the wear actually happens. These bushings seat between the gears inside the power window motor, cushioning metal-to-metal contact and maintaining the precise spacing the gear set needs to cycle without binding. Replacing them addresses the root cause of sluggish or noisy window movement rather than masking the symptom.
Exact fitment for the Fox-body Mustang. Engineered as a direct replacement for OEM reference E4ZZ-6623394-BUSH, the set matches factory dimensions so no modification or shimming is required. Drop the motor, swap the bushings, and reinstall with confidence that the fitment is correct.
A simple fix that extends motor life. Worn bushings force the motor to work harder with every cycle, accelerating gear wear and drawing higher current. Fresh bushings restore the smooth, low-friction operation the motor was built for, protecting the surrounding gear set from premature damage.
