As the title suggests, I appear to have a problem with a noisy diff...or at least that's what I think.
The noise sounds like a slight grating/slipping noise and only occurs when moving off from standstill, in first gear and on an incline when accelerating more than usual to get momentum. It doesn't do it when moving off under normal load, i.e. level surface. When it does occur, it only lasts a split second until the car gets momentum.
As a result, the engine came out last year and the engine/gearbox was split. The gearbox was rebuilt last year and all bearings, layshaft etc. replaced. Whilst at it, I also fitted a new clutch and dismantled the diff, replacing the bearings, planet gears, fibre washers and crosspin. The only thing I didn't change were the pot joints/driveshafts.
Having removed the pot joints, one of them appears to have slightly smoother spleens. I've ordered a new set from Minispares hoping this will sort the problem but whilst I'm at it, is there anything else I should be looking for/checking?
Many thanks for your help in advance.
