Default having some issues adjusting my rear suspension

Im putting my car back together and when i load the suspension, my drivers side is sitting like 4'' higher then the pass. side. I have adj. everything...

--lca adj. dead nuts on center/center
--pinion angle is set at -2.5
--sway bar is still off the car

Now 2 issues...

Well the drivers side is sitting a few inches higher then the pass. side or the pass. side is sitting lower, whatever way you wanna think about it AND VISUALLY my rearend needs to get adjusted towards the right side but when we measure from the center of the axle out and use a plum from the outside of the fender and centered with the axle, TECHNICALLY it needs to come out towards the left side, wtf...

what do you mean when you load the car? when you sit in it or when you actually give it gas and hold the brake to load the suspension? also do you have a spool?

yes springs are the same, and does the same thing if i switch the springs to the other side....

car loaded for this is when the car is sitting with the car weight on the springs, not under acceleration

A TQ arm hitting the floor can def be an issue. I had with my old 94, a un cut BMR TQ arm on a Moser 12 bolt, since the 1st set of holes were not cut, it brough the arm out closer to the tunner and it want popping over the rear seat belt bolt and made a LOUD audible pop, I had to cut the TQ arm down to properly angle the TQ arm. Also we noticed the tunnel "clearenced" itself.

are you positive the springs are centered on the cone at the top? is the car lowered at all?

How are the front springs?

It might be time to put it on a chassis rack and check it out

you dont have a bolt from the panhard bar grabbing a coil on the spring do you? I have seen that happen on a buddy's car.

You took it on a drive on lift so the suspension can be loaded?

No, as i stated above, in my case its loaded with just the weight of the car preloading the springs, not launching.

well i figured it out. Pretty sure it was my panhard bar binding things. Took it off, loosened my TA bolts a little so it was free. My cage builder said i needed to adj. my control arms first and that will "preload" my springs equal. So i set them both at 19'' center to center and lowered the car on the springs. Bounced on it and shifted it side to side to settle it in. And then after that it was sitting perfect. Raised it back up with the springs loaded with the car weight and finished it all back up.

So my final word is aparently you need to adj. the parts in a certain order or youll be all over the place like i was doing things all wrong, lol. But it was a learing curve so now im just that much more smarter.
