Okay guys, I have a 2005 350z Track. When I take off slowly, kind of like half clutching it, my car thumps a lot in the rear and makes a horrible noise. It sounds like huge boulders are being dropped on my car.

When I got back from my first deployment I had to get my clutch replaced because the person I let drive it didn't drive it properly.

I now have a Carbonetic clutch in there. I never had this problem with the stock clutch and I heard carbon clutches were supposed to be better so I'm really confused as to what the problem is.

I took it to the same mechanic who installed the clutch and they weren't able to figure out the problem. Any help would be greatly appreciated! Thanks in advance!

 

But anyway, if its In the rear, I'm hesitant to say that it's the clutch. Sounds more like the differential to me, but it could be a number of things.

 

Differential.

 

Sorry for posting this in the wrong place! I'm just in a hurry to get this fixed! If its the differential how would I go about getting this fixed? Again, I appreciate all the help!

 

Take it to a mechanic?
