i've replace 3 CV joints now but still I'm getting a really bad knocking from the front end, its a rotaional knock/grind. the only thing i can think of now is its the gearbox. but it happens weather in or out of gear clutch in or out, does the quattro gearbox have like a transfer box that could of had it or developed play in it? I'm really stumped and 3 CV joints and few hundred quid worse off and now I'm broke! Its going into my local garage (non dealer) tomorrow but that'll cost an arm and a leg.
