yet another problem..........

ok guys problem being when i take my car to end end of its rev range and go to change gear i get a bad vibration/grind thru the chassis.

first thoughts was gearbox as it was on its way out anyway, but problem was still there but not as bad as before.

then noticed my exhaust was sitting hard againts the gearbox mount so got that sorted out and now it seems alot better but every now and again i still get this vibration/grind/rumble feeling thru the whole chassis.

but its only at high revs and when i bach off the revs this happens so it can only be one of 2 things i recon

propshaft or rear diff???


any help guys?
