Hi all,

Are these differentials ZF or Maserati/Ferrari derived ? I think I need to rebuild mine as it has started to clunk heavily whit on/off acceleration. Might be easier and cheaper if it was German derived.

Looks like QP Evo and 3200GT has the same diff - at least in construction but maybe not ratio. Are there any known troubles with the 3200GT diff ?

Some are known to be a bit clunky from new.

Are you sure it’s the diff and not the propshaft/driveshafts?

Yes,I've heard that they can be a bit loud but mine has really been quite ok until this year. I checked a bit more yesterday and the clunk is very audible from inside the diff. The clunk is rather sharp and seems to come from where the ring & pinion is. It might be a problem with the backlash. The propshaft and driveshafts seems fine and quiet.

From pictures I've found online it looks like the unit is produced by O.M.R so the hope of easily obtainable ZF-parts is out.
