Hi,

I've recently purchased a 325 sport, i'm looking for some help with what i think may be a diff problem.

The noise experienced is a clunking noise once the car is warm, this noise only seems to occur when going at slow speeds in first and second gear when coming on or of the throttle, crawling at slow speeds or pulling away....almost as if you can here the diff engage/disengage

Any idea's on what the issue may be and any advice appreciated

:D

It could be the diff but it doesn't sound like expensive internals... i'd start with the easy things first. Diff bush (and is the bolt tight) and is the backplate ok? They tend to crack around the diff bush, making it flappy! forward diff mounting bolts tight. all driveshaft/propshaft bolts tight. check condition of the guibo coupling on the prop (rubber donut behind the gearbox). Engine and gearbox mounts. All easy to check out.

It's not at all unheard of for an LSD to fail, i know as i spend a lot of time rebuilding them for people! However it's an expensive first place to look.

Any chance it's got the incorrect type of oil in it?

Could that be causing the noise only at low speeds? Strong and pulls well with no whine...I was thinking of changing the oil in it anyway. Thanks for the suggestion, i'll know what to check next if all the bolts etc are ok
