Spicer Front Upper & Lower Ball Joint Master Kit for 1971-1980 International Scout II, Traveler & Terra (Dana 44, Both Sides)

Eliminate loose steering play, fix front-end wander, and restore original factory handling to your vintage 4x4 with this genuine Spicer Front Upper & Lower Ball Joint Master Kit. Specifically engineered as a high-durability, direct original equipment replacement for 1971–1980 International Harvester Scout II, Traveler, and Terra configurations, 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 International Harvester platforms, the front steering knuckles pivot on a rugged dual ball joint design to translate your steering inputs while supporting the immense weight of heavy iron-block AMC or IH V8 and inline engines. Over decades of demanding agricultural work, deep mud bogging, or highway driving, the internal seats of these factory ball joints naturally dry out, flat-spot, or suffer severe water intrusion. Worn ball joints introduce dangerous play into the steering knuckles, leading to loose steering tracking, accelerated front tire tread wear, lane drifting, or low-speed front-end clunking. Left unaddressed, severe ball joint wear alters front wheel alignment, strains your steering gear, and risks structural component failure on the road or trail.

This original equipment manufacturer (OEM) replacement master bundle features heavy-duty ball joints forged from premium-grade steel, heat-treated for maximum fatigue resistance, 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. Built to match vintage factory performance and demanding trail duty, these premium replacement units are engineered with a durable, maintenance-free internal seat design alongside multi-lip boot seals to securely lock out trail water, grit, and mud.
