FFS, what is it now?

[XRated]

Wellll my latest problem.. Sorry it's a bit hard to understand but I can't explain it very well unless you're actually sitting in the car.

Basically when I floor my car, something is happening at the rear. It's kind of like a "clunk clunk knock" struggling sound. At first I thought it was fuel related (crap fuel, need new plugs/leads or something), but now I can feel the knock so I am thinking it is probably somthing physical like the diff. If you think of an exhaust being loose and knocking under vibration it's a bit like that..

What is it this time? :togo:
