IRS is aligned wrong. Get it realigned. My friend with an 01 Cobra had the same problem.99svtdlb said:I have a 99 cobra and when I get on it, the car wobbles/weaves in the rear at about 80+ mph as I accelerate. It gets dangerously worse as I go faster. What in the world would cause this? Could it just be a bushing? Something with the IRS? Any ways I can check without taking it to a shop? Thanks.

damn, I'll have to ask my friend. I think it actually had to do with the rear caster/camber. You can also call the ford SVT line direct. There # is on www.svt.ford.com99svtdlb said:how much did that cost?... are you talking about the actual IRS being aligned or getting it caster/camber aligned for the wheels?
...where could I get this done?

I'm pretty sure that is what it is. I'll know tomorrow afternoon when I see him. I know the ford dealer he brought it to ended up calling SVT, and SVT told the dealer what had to be done.99svtdlb said:dan...let me know what your friend says because if it's simply the rear caster/camber, it should be a cheap fix. Thanks. I'm assuming that it just needs to be put back into the correct specifications.

When I drive it normally, it drives straight as a whistle. But when I get on it...it weaves in the rear and gets dangerously bad at around 70-80mph.

d90212 said:perhaps your feeling an imbalance in the wheels. swap the tires from front/rear. does the imbalance follow? this would follow as well if theres a bubble in the tread.
also you should have received a printout of your alignment, before and after printout. if the printout looks good, it would probably rule out the alignment and need to look at either the suspension tweaking under load, drivetrain, or rearend..
Disturbed One said:Even if the print out is good for the alignment, I know a couple guys/tech's that were fired for doing a 4 wheel alignment just by adjusting the heads mounted to the wheels of the car.
If the alignment is ok, I'd be looking for something bent, broke, loose.... anything that could contribute to it. All the lugnuts tight on the rear wheels??? might seem silly but I've had people complain about a wobble the faster they go and when I go look at the vehicle there's 2 lugs missing, 2 holding on with 3-4 threads and 1 lug all the way down finger tight.
