LEFT COAST
I am having some kind of problem with my rear suspension on my 03 Mach 1....My rear setup consists of Maximum Motorsports adjustable lower control arms, MM panhard bar, Bilstein HD's, stock uppers & diff bushings, MM full length subframes, & pro kit springs. The front is MM coilovers, CC plates, Bilsteins, steeda X2 balljoints & bumpsteer kit...

The problem is I will be rollin my car on the highway & if I downshift & punch the gas my car feels like it wants to shimmy to the left. When u let off the gas it shimmys back to the right. This problem didnt occur until I took my car to the track a couple of weeks ago. When I was at the track I raised the lca's all the way up in the rear & then the problem occured after I lowered the car back down.

I jacked up the rear of the car & everything looked ok, but it was dark so It was kinda hard to see the uca bushings. The only thing I can think of would be either the panhard bar is out of adjustment or my upper control arms or diff bushings are worn, or it could possibly be something in the front, but my steering feels ok....


I am gonna be getting a MM torque arm installed soon, but at this time I dont have the cash to pay for the install so if it is some type of issue with the uca's or diff bushings those wont matter anymore since the TA eliminates those. But I just need to get a temporary fix since it doesnt feel all the way safe to be driving around like this....... Any suggestions or info would help....Thanks!!!!
 
sounds like bushings to me, or your control arms aren't adjusted equally.

I dont have a jack here at the house, so its hard for me to get my car in the air to look at the upper bushings. It could be that the lca's arent adjusted correctly. How do i get an accurate measurement because the fender edges arent an accurate way to measure....
