'01 GT Noisey rear suspension
I have an '01 GT that was modded before I got it 8 months ago. Mods to the suspension are Bilstein coilovers (lowered 1 1/2"), MMS caster plates, full length weld in frame connectors, MMS panhard bar, MMS LCA's, UCA's are still stock. Recently I had to replace my front wheel bearings and while I was doing that, I adjusted my front shocks so my ride height was the same front to back. Plus, I laid into the skinny pedal a couple of times. OK, background is set, on to the questions. I now have a loud klunk coming from the rear of the car when I am making a full right turn in or out of my driveway, the apron has a 1" curb with about a 2 degree incline. I have inspected my torque boxes and don't see any visible cracks or deformities. Yet the sound is so loud that something should be visible. I have pried on every part under the rear of the car, both with it hanging and under load, and cannot get any abnormal movement. I have even laid in the trunk while someone else replicated the sound and can pinpoint the sound to the area almost in the middle of the rear seat floor area. Could my torque boxes still be loose even though there is nothing obvious? Or could it be a bad bushing somewhere? Possibly posi clutch packs going south?
