Lately I've been hearing some banging underneath the car when driving. Only have 70 miles on the new rear end. I jacked it up with the suspension loaded and found that my Torque arm is touching right against the driveshaft tunnel. and is hitting it. Look at pics below. You can sort of see the rub marks.





My car is only lowered on BMR springs. Should I not have the torque arm on the top hole on this pic below for the trans mount?

 

I think they recommend the second hole from the bottom on a lowered car, seeing how it works out, and adjusting from there.

 

^^^ true dat

with the car lowered you will need to use one of the bottom holes in the pivot link.

 

Thanks Eric! I will switch it to the second hole from the bottom?

 

Yes second hole from the bottom will fix your issue. Any questions please let us know.

 

Thanks guys.

I also called Wavetrac like you recommended to find out what oil they prefer to use after break-in and they recommended 75/90 synthetic, as long as it isn't redline

 

Haha amen, found that out the hard way after I lowered mine.

 

lol did you have the same problem with torque arm banging?
