Spicer Front Upper & Lower Ball Joint Master Kit for 1974-1978 Jeep Wagoneer, Cherokee & J-Series Trucks (Dana 44, Both Sides)

Eliminate loose or wander-prone steering, correct uneven front tire wear, and restore original factory handling to your classic full-size Jeep (FSJ) with this genuine Spicer Front Upper & Lower Ball Joint Master Kit. Specifically engineered as a high-durability, direct original equipment replacement for 1974–1978 Jeep Wagoneer, Cherokee, and J-Series trucks, this package contains all the primary heavy-duty structural components required to fully rebuild both the driver and passenger side steering knuckles on vehicles running open-knuckle Dana 44 front axles.

On classic full-size Jeep platforms, the front steering knuckles pivot on a dual ball joint design to direct steering inputs while supporting the full structural weight of the vehicle’s front end. Over decades of off-road trail riding, farm use, or heavy highway cruising, the internal seats of these factory ball joints naturally wear out, dry up, or experience water entry. Worn ball joints introduce dangerous play into the front axle knuckles, causing your steering wheel to feel loose, non-responsive, or wander across the lane. Left unaddressed, severe ball joint wear can lead to front wheel alignment drift, accelerated wear on your steering linkages, and potential catastrophic separation of the knuckle from the axle housing on the road or trail.

This original equipment manufacturer (OEM) replacement bundle features heavy-duty ball joints forged from premium-grade steel, heat-treated for maximum fatigue life, and precision-machined to exact original factory tolerances. Sourcing a genuine Spicer kit ensures a perfect press-fit into your factory inner C-axle ears, eliminating the risk of loose housings or premature component failure. To match vintage factory specifications, these replacement units are built with an integrated grease-service architecture, allowing you to flush away moisture and trail grit during routine maintenance.
