Recently, I installed a set of TeraFlex adj CAs on my 2dr JK, however, before the installation, I was using cam bolts for the caster angle, but they didn't do very well.

I have encountered a problem after the CAs installation, which are my axles moved forward and backward, and they indeed moved closer to the bumpers.

Here is the detail:

To get the right caster angle(6 degree) for the front axle, I adjusted the front lower CAs a little longer than stock ones, at the end, I found the front axle moved forward a little bit(about 3-4cm).

For the rear axle, I need to get the rear bump stops balanced, so that I adjust my rear lower CAs a little longer as well, after the adjustment, I also found rear axle moved backward as well(maybe 3-4cm too).

Even with the current CAs adjustment, my rear bump stops are not totally balanced, they are still a little sideling. Do I need to adjust the rear lower CAs longer to get the bump stops balanced or there is some other way?

By the way, my lift height is 4.5" which including a RE 3.5" lift and 1" BL, and my tires are 37X12.5R17.

 

if you had cam bolts, the mounting holes were most likly cut out so the bolts could rotate. These pictures are from the Rough Country install on project-jk.

 

What do you mean by your bump stops are not balanced and that they are sideling? Longer control arms will move your axles farther from the center of the vehicle which is a good thing as it compensates for the closer movement of the axles caused by the lift. With the control arms the axle is on a pivot from the frame attachment point of the control arms.

Teraflex makes an axle mounted rear bumpstop extension that moves the pad of the stop forward to better contact the axle compensating for the rearward movement of the axle due to longer control arms/axle tilt.

 

I didn't do any modification to the control arms brackets when I was installing the cam bolts. Maybe that was why the cam bolts were not working right, but for now, I think I was right that I did no modification to the brackets.

 

What I mean the rear bump stops are not balanced is the surface of the rear bump stops
are not level, so that the bump stops will not giving 100% work when the vehicle is bumping.

 

As long as they are making contact with the axle pads it shouldn't make a difference. The important thing is the pinion angle is correct for the driveshaft. Everything when modifying a Jeep is a compromise.

 

Thanks for the reply. I will change my rear drive shaft as soon as possible, then I will have more adjustment rooms for the rear control arms.
