R33 Diff Problem

[defari]

ok so at low speeds, especially in stop / start traffic, whenever I give a slight bit of acceleration to get the car moving, I hear this 'squishing' noise from the rear of the car just as i let the clutch out..

Then whilst gently accelerating in traffic i.e gas on/off etc, if i stop accelerating before 20km/h or so it makes this slight metal tap noise (only once) but if i tap the gas again it will make the same 'clink' or noise.

I noticed it about 12 months ago, drained and replaced the diff oil - didnt quite go away but it made a difference noise wise.. the last month or so the noise has got a little bit worse. The car doesnt seem to be affected performance wise.

any ideas? I'd get a video / audio but the car is too loud

When you replaced the oil was it metallic in color? What sort of oil did you replace it with?

[defari]

i used castrol SAF-XA rear axel diff oil

when i drained it the previous oil was a dull yellow colour and smelt like onions that had been deep fried about 100 times..

yeah that pretty normal smell wise. Maybe stick a bottle of Fiction Modifying additive to see if that fixes your problem. I use it in my 2-way to stop it clunking and grinding, i use penrite additive but chryler-jeep and ford motorsport also make it

there was a small amount of tiny metal shavings on the drain bolt - i assume the oil hadnt been replaced in a while..

cheers ill check it out

it maybe a thought to check your bearings for your rear wheel hubs. i had same issue and one of the bearings was farkd.

replaced that and it was all fine.

also check your cv joints for play as that can do it too
