Ever since I lowered the car, I have rear end vibration under acceleration. You feel it between 3 and 4k RPMs real bad. Righteous Spec told me it was the axle cups or some ish like that and that it's an easy fix. Can anybody help me do this "easy" fix? I don't like messing with stuff like this since my S is my DD and I'm not experienced enough yet. And no, I don't want to pay someone to do it for me. I'd like to actually do the work with someone showing me what needs to be done.

 

Yes it's the axle cups. You can swap them if you want to go the free route. I've done mine twice. Now I have axle spacers because I couldn't swap them anymore. It's not to hard.

 

Dude. You know to hit me up with this stuff. I'll help you out homie.

 

Matter of fact. I need to swap mine around too. So we can make a day of it.

 

I have a extra set of axle spacers for sale as well. Only had about 1k on them. lol!

 

I wonder if I'm feeling the same???
I first noticed it while on the dragon trip. It was on an uphill quick turn on a extremely smooth (fresh paved) road. During acceleration and turning I would feel a very faint vibration. I barely feel it in fla. the roads are not as smooth.

Any clue?

 

Yes. You'll mainly feel it under load or torque. Most noticeable in first thru third. Won't feel it cruising

 

Sounds like you guys need axle spacers.

 

How much?

 

B I have them. Unfortanatly It'll happen with or without them eventually.
