Description

RockJock Uni-Balls for Front Axle Housings are used in 3-link suspension applications, where the passenger s side upper control arm has been eliminated and all of the suspension load is now being applied to the one axle housing mounting location. Our Uni-Balls press into the stock bushing holes on the casting side, driver s side ONLY) of the front differential housing and provide a durable solution that incorporates a 5 8 in. thru-bolt hole for heavier hardware. This Uni-Ball will press into a stock JK or a stock TJ LJ XJ MJ ZJ housing, as well as aftermarket replacement differentials from companies such as Dana, UD-60s), Dynatrac, East Coast Gear, Fusion 4×4 and Currie Enterprises, cast center housings ONLY, does not apply to 9 in. fabricated style differentials). Additionally, most in. aftermarket differentials that are intended for installation in a JL JT vehicle, still retain the bushing specs. of a JK bushing, making this the applicable Uni-Ball to install in an aftermarket differential, again, cast center only, not 9 in. style going into a JL JT., for STOCK JL JT housings, see our RJ-301002-101 Uni-Ball. The mounting width of the center pivoting assembly is 2 in., to allow it to fit into the fork on JL JT JK TJ LJ XJ MJ XJ front upper control arm, however, the 5 8 in. thru-bolt hole will require drilling of the bolt hole in the control arm fork. Uni-Balls feature a sealed bearing assembly, so no greasing is required. Finish is clear zinc plating.
