Spicer Front Upper & Lower Ball Joint Master Kit for 1976-1998 Jeep CJ5, CJ7, Scrambler, Wrangler YJ/TJ & Cherokee XJ (Dana 30, Both Sides)

Eliminate loose steering play, fix front-end tracking issues, and restore crisp handling to your classic or trail-ready vehicle with this genuine Spicer Front Upper & Lower Ball Joint Master Kit. Specifically engineered as a high-durability, direct original equipment replacement spanning 1976–1998 Jeep Dana 30 open-knuckle front axles, this comprehensive package contains all the primary heavy-duty structural components required to fully rebuild both the driver and passenger side steering knuckles simultaneously.

On classic leaf-spring CJ models, early Wrangler platforms (YJ/TJ), and compact Cherokee (XJ) sport utilities, the front steering knuckles pivot on a critical dual ball joint design. This layout is responsible for directing all steering inputs while supporting the full structural weight of the vehicle’s front end. Over decades of off-road trail riding, commercial use, or highway driving with oversized tires, the internal seats of these factory ball joints naturally wear out, dry up, or experience water intrusion. Worn ball joints introduce dangerous play into the front axle knuckles, causing steering wheel wander, irregular tire wear, or low-speed front-end clunking. Left unaddressed, severe ball joint wear compromises front-wheel alignment and puts extra strain on your steering linkages.

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 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 guarantee long-term serviceability on vintage and off-road applications, these premium replacement units are built with an integrated grease-service architecture, allowing you to flush away moisture, trail mud, and grit during routine maintenance.
