TJ control arm install
« on: March 11, 2017, 10:13:36 PM »
I have some Rubicon Express lower control arms



I asked a few folks and I'm still not sure which end goes to the axle and which end goes to the frame...  Rubicon Express instructions show the centered end going to the frame and the teardrop end going to the axle with the tube towards the bottom, but that seems backwards to me...  I would want the superflex joint on the frame side keeping it safe from damage...

I appreciate any experience with the RE set-up...

It's all in the grease fittings.

If you mount it with the offset side down at the axle , that puts the grease fitting out of the way . The offset is to help with torque steer and not have a bunch below the axle. When I built my 4 link I made the square stock run right under the lower fitting to act as a skid .   FjR68

All mine are longer side down.
I have no idea what I'm doing... but I did stay at a Holiday Inn Express last night.

Thanks for the feedback!  For my rears I'll mount them with the longer side down (rubber bushing on both ends for the rears)  my fronts are still good, so I'll save the arms with the flex joints for that application when I need them

Pretty sure the offset joint is to clear the spring mount from hitting the lower control arm at full droop. My lower control arms hit my spring perches when the axle droops so this design prevents that from happening.
