RockJock JL/JT Aftrmkt. Diffs & JK/TJ/LJ/XJ/MJ/ZJ Stock and Aftrmkt. Diffs Johnny Joint Uni-Ball

RockJock is known for making solid suspension components for off-road vehicles. This Johnny Joint Uni-Ball is designed for 3-link suspension setups, specifically where the passenger-side upper control arm is removed and all the suspension load goes to a single axle housing mount. It presses into the stock bushing holes on the driver's side of the front differential housing, offering a strong solution with a 5/8 inch thru-bolt hole for heavier hardware.

This Uni-Ball works with stock Jeep Cherokee, Comanche, Grand Cherokee, and Wrangler housings, as well as many aftermarket differentials from brands like Dana, Dynatrac, and Currie Enterprises, provided they have a cast center housing. It's also applicable to most aftermarket JL/JT differentials that retain JK bushing specs. The mounting width is 2 inches, fitting into the fork on many Jeep front upper control arms, though you'll need to drill the control arm fork for the 5/8 inch bolt. It features a sealed bearing assembly, so no greasing is needed, and has a clear zinc plating for corrosion resistance.

This part is intended for the driver's side of the front axle housing. If you're working on a stock JL or JT housing, you'll need a different Uni-Ball (RJ-301002-101). Remember that the 5/8 inch thru-bolt hole will require drilling the control arm fork to fit.
