Drivetrain Foxbody Rear End Maxed Out

Bryant Magana · Apr 1, 2020

I have a 89 foxbody On Rear True coilovers and it has been sitting for a couple months while I put new parts in and when I went out to go look at it I noticed my passenger rear quarter panel is laying on my wheel. I have new upper control arms, tubular lower control arms, upper and lower torque box reinforcments and subframe
connecters as well as new rear end carrier bushings. does anyone know why this sudden change? I adjusted my coil over on that side to max ride height and still sits really low

I even switched coilovers side to side aswell as wheels and same issue really low on one side

I tightened all rear suspension under load aswell. Could the new upper/lower torque box reinforcments cause that issue? anyone have this issue before?

Is the ground flat where you have it ? Is the opposite front corner high ?

Yeah it is, its been parked in the same spot as always. Also the rest of the suspension is even just that corner came down for some reason?

Springs too short?

Measure the length of both coil overs and while you are there inspect your torque boxes and where the coil over mounts to the body, that area of the body was not designed to carry weight, that is where I would start looking.

same length on both sides, also switched the coilovers side to side and problem still stays on my passenger rear

Thank you! Coilovers are equal, torque boxes aren't ripped out. and coilover mounts seem fine. Lost on to why this happened so randomly. I know my passenger front was a little higher than my driver front by an inch so i lowered it to match but I don't think that would cause this much of an issue to my passenger rear? i just maxed my coilover in length and got an little less than half of inch gap between my quarter and wheel. Not sure why this randomly happen? it used to sit higher perfectly. was wondering if a bad subframe connecter install maybe caused this? even if it was fine for a year. not sure

Are suspension mount points how they should be (nothing broken or collapsed)? Is the coil-over mount collapsed or damaged? Are the coil-overs adjusted the same (or essentially the same)?

Pics of the condition? Pics of the suspension mount points?

Subframe connector would have nothing to do with rear suspension (unless your chassis is so rotted and broken that the SFC are holding everything together - I assume your chassis is in good condition if you went the effort to install torque box reinforcement).

What suspension are you running on the front?

this is what i have to do to get them even. the passenger side rear is raised almost to max and sits just as low as the other side..

Swap the rear coil overs right to left and see if the problem follows, if it does then I would say the springs are the problem.

did that! same issue

Same side?

Yeah same side with the same issue. Not sure how this happened or if anything with the front is messing with the rear that bad.Torque boxes aren't ripped out.

Passenger Rear & Driver Rear. Driver does not rub. Passenger rubs.

Bryant Magana · Apr 2, 2020

I can adjust my driver higher than I would ever want. But my passenger is maxed out height and thats as high as it goes

General karthief · Apr 2, 2020

Short of swapping the front coil overs side to side (I think that would be a major pain) drop the adjustment all the way off so there is no spring holding up the front and see if it is still off.
