Dana 44 Front Differential Ball Joint Kit

The Yukon Ball Joint Kit provides a robust replacement for OE ball joints, specifically designed for the Dana 44 front differential. This comprehensive kit includes one upper and one lower ball joint, along with all necessary small parts, Grade 8 hardware, castle nuts, c-clips, cotter pins, and zerk fittings. Constructed with superior materials for enhanced durability, the kit features a CNC-machined forged SAE 1045 carbon alloy steel housing for extended joint life. The hot-forged, induction heat-treated 4140 chromoly ball stud ensures exceptional strength and longevity. The upper joint's bearing utilizes a carbon steel design, while the lower joint employs military-grade acetal bearings for their advanced anti-friction properties and dimensional stability. Extrusion rolled threads further enhance the strength compared to standard cut threads. Durability is further assured by a dual-stage boot system, featuring a synthetic Neoprene/CR outer boot and an inner seal/pancake boot. These protect the spherical joint and bucket from contaminants like gritty road grime, oil, gas, engine fluids, and extreme temperatures. The greaseable, pre-threaded zerk housing allows for easy lubrication maintenance. Installation note: A break-in period of 300 to 500 miles may result in temporary memory steer. The kit comes with a lifetime warranty against manufacturing defects.
