Ford Transfer Case Bronco 66-77

The Ford Transfer Case Bronco 66-77 polyurethane bushing kit from PROTHANE is engineered to address a critical weak point in early Bronco and Ford compact SUV drivetrains. Original rubber bushings deteriorate over decades, allowing excessive transfer case movement that compromises driveline alignment, increases vibration, and accelerates wear on adjacent components. This replacement bushing restores structural integrity and handling precision to vehicles running 1966–1977 Ford Broncos and related compact SUV platforms.

PROTHANE's polyurethane formulation outlasts OEM rubber by a significant margin, resisting heat, oil exposure, and UV degradation while maintaining compliance across a wider temperature range. The black polyurethane compound is stiffer than stock rubber, which reduces transfer case deflection under load and during gear changes—a key benefit for vehicles used in off-road conditions or towing. The compact 4.2 x 3.2 x 4.8-inch kit weighs just 1.35 lbs, making it a direct bolt-in replacement that requires no modifications to mounting brackets or driveline geometry. Installation is straightforward for anyone with basic mechanical skill and a socket set.

This bushing is ideal for restorers, off-road enthusiasts, and daily drivers keeping first-generation Broncos and Ford compact SUVs on the road. Owners tackling vibration issues, clunking noises during acceleration, or noticeable driveline play will benefit most from this upgrade. The kit is compatible across the entire 1966–1977 Ford Bronco lineup and related compact SUV applications; verify fitment with your specific year and model before ordering. Proper installation ensures years of maintenance-free operation and improved handling feel.
