Need help super bad
I'm installing a Rubicon Express bb. It has a 1.75" in rear and 2.5" in front. I've completed the rear, except I can't get the track bar on frame end attached again. How can I shift it up and forward? The tech I bought all the components from told me I would not need a relocation bracket with it only being 1.75". HELP!!!!!! Jeep is immobile.

Ended up placing jack under the front of the rear pumpkin. Jacking on the vertical heavy seam. I was able to place enough front pressure on the rear axle. It caused the rear axle to pivot up and forward. Thank you again.

Did you loosen all upper and lower control arm bolts in addition to the trackbar bolts for the install and wait to retorque them until the full weight of the vehicle was back on the ground at the new ride height?

Not major trouble but it's advised to.do it it puts un Nesasery torque or twist on the bushings due to the change in angle

If the bushings are twisted/preloaded/binding to the wrong ride height, they will fail prematurely, and you will have a jittery ride. Kind of like running on a twisted ankle.
The bushing bolt sleeves will twist away from the bushings, the bushings will crack/separate, etc.
Loosen all the bolts in all 8 control arms and both trackbars, vigorously rock the vehicle side-to-side and forward-and-back, and then retorque everything to spec. This should be done with the full weight of the vehicle on the ground so that the bushings are pinched between the brackets in a neutral position.
Lower control arm, trackbar, and rear upper arm bolts have a torque spec of 125 ft lbs. Front upper arms have a spec of 75 ft lbs.

Thank you. I am going to loosen them now before I place the rear tires back on. I still have to do the front axle coil springs spacers. I have not touched the front yet. I wanted to get the rear sway arms off and replace with the new, so that I could reuse the rears up front.
