I have not noticed this issue until one of my buddies (about 260lbs) got in the car for this first time. I have had other smaller people in the car and never had the scrapping(SP) problem...The sound is coming from right in the middle of the car underneath. I climbed under the car thinking i may have a ujoint kink issue and it looks like the Driveshaft is rubbing on something which is in the area of the parking brake. the car does have eibach springs so i guessing that is playing into it. so beside the obvious answer of loosing weight and dont carry people over 200 lbs what possible solutions are there?

 

Its your DS rubbing because your pinnion angle is off. Your Adj UCA will fix the problem. I'm betting you don't have relocation brackets? This would explain it.

 

i do have relocation brackets but I have not installed them yet...plus I have not done the pinion any adjustment yet...

 

Let us know how it works out.
