TJ - Anyone Install Rubicon Express long arm kit?
Anybody install a Rubicon Express long arm kit on a TJ?
Over weekend I helped a friend install a Rubicon Express long arm kit with 5.5" lift springs on his 2000 TJ (4.0L, 5spd, D44, D30). Also installed the R.E. CV drive shaft and SYE kit that does not require disassemble of transfercase.
Mostly all went well... the instructions were next to worthless. Missing brake line mounting bracket (fabricated) and missing grease fitting (had some in drawer). Otherwise this kit is beefy.
This kit includes new center frame crossmember. The front and rear control arms attach to the new crossmember. The new crossmember is mostly flat so the engine/transmission/transfercase is all tilted with the output of transfercase now higher. (note: we did have to lower the radiator fan shroud so the fan would not hit)
Problem is : The CV driveshaft binds against itself.
The instructions for entire install were vague so it is possible we missed a detail.
I realize the springs will settle an inch or so and that will be maybe be fine for on road driving. But what good will that be when on trail and the rear axle droops? ...at any rate how is it supposed to be driven to settle the springs in? We rotated the rear axle up much as possible without needing to relocate the spring mounts.
Who has installed one of these kits? Did you have similar problem? Is something supposed to be done with the OE trans mount and the new crosmember to keep the rear end of transfercase down?
Any suggestions? [img]images/graemlins/confused.gif[/img]
