Spicer Front Upper & Lower Ball Joint Kit for Dana 30, 44 & 50 Front Axles (Single Side Set)

Eliminate hazardous steering wheel play, cure aggressive front-end "death wobble," and restore factory-smooth tracking to your rig with this genuine Spicer Front Upper & Lower Ball Joint Kit. Specially engineered for rugged 4WD truck and SUV applications utilizing Dana 30, Dana 44, or Dana 50 solid front axles, this single-side service package bundles both the upper and lower heavy-duty ball joints into one convenient, drop-in replacement set.

On solid-axle 4x4 platforms, the upper and lower ball joints act as the structural pivot points for the entire steering knuckle assembly, bearing the combined weight of the vehicle and managing severe off-road steering loads. Over high mileage, or when running oversized off-road mud tires and suspension lifts, factory internal plastic liners naturally compress, degrade, and tear. Once the seals fail, road grit replaces grease, causing internal socket slop. Worn-out ball joints present themselves through loud metallic popping or clunking sounds over bumps, wandering steering tracking at high speeds, uneven front tire wear, and erratic front-axle vibration.

This original equipment manufacturer (OEM) kit updates your steering knuckle geometry with professional-grade components. Precision-engineered from premium-grade steel, choosing a genuine Spicer replacement ensures strict original equipment tolerances are met—giving your steering assembly the exact structural stiffness and durability required for reliable on-and-off-road performance.
