      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 4x4 and Currie Enterprises (cast center housings ONLY, does not apply to 9 in. / fabricated style differentials).
      Additionally, most aftermarket 60s 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 your aftermarket JL/JT differential as well (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.


      Kit Fits:

      JL Wrangler Unlimited (4-door) – casting/driver’s side ONLY w/ aftermarket differential w/ JK bushing specs. ONLY
      JL Wrangler (2-door) – casting/driver’s side ONLY w/ aftermarket differential w/ JK bushing specs. ONLY

      (1) Installation Tool (RJ-530000-1 and RJ-530001-3)

      Uni-Ball Specs.:

      CNC machined steel outer barrel, clear zinc plated (1.793 in. on the press fit area)
      Stainless steel, sealed spherical bearing assembly
      Stainless steel high misalignment spacers (provide for a 2 in. mounting width and a 5/8 in. thru-hole)

      Notes:

      Uni-Balls are ONLY used on the driver’s side of the differential housing where they install into the machined hole in the cast iron loop on the top of the differential casting above the differential cover. Uni-Balls are NOT for use on the passenger’s side of any differential
      A 5/8 in. drill bit and drilling of the control arm mounting bolt hole in the control arm fork will be necessary for assembly.
      **BE AWARE** the factory frame end of your upper control arms are NOT sufficient to support being your only control arm! You must modify/replace your frame bracket so that a 2 1/2 in. Johnny Joint may be installed!

      Fitment:

      RockJock RJ-301001-101
