On my mates car there is a clunk coming from the rear of the car, the car even jumps at times from side to side slightly only dose it when you give a lil gas.

The diff locks fine and dosen't kick or do anything when in a drift.

Is it the Diff??

what car is it? cwp could be after breaking or chipping a few teeth? jack up the car so the 2 back wheels are off the ground spin the wheel with your hand see can you hear a metal against metal sound in where the diff is, suppose no harm to drain the oil and look for metal filings before you go stripping it,


OR

it could just be the normal workings of a very harsh diff like cusco or kaaz for instance

bob my own silvia went like this realy bad clunking and banging in it thought the diff was fcuked and it got louder as the days went on thought the oil may have gone thin so changed the oil and its back to normal now

might sound like a silly question but are you running the same tyres on each side?

The diff is transmitting the power to the wheels, straight line or not so it could be the diff.

Check the rear subframe bushes as well.

It not a silly question for my mate cause he actualy has different weidth tyre's on the raer just checked he so stupid,

He got new alloys so see what it like when they go on..

well tyres on an aftermarket diff have to be the same.
if you have 17/45/215 on the left rear you need 17/45/215 on the right ;)

He's a dummy told him not to be usin different tyres that it couldn't be good for it in some way but i didn't tink it would effect the diff like this thou..

thats your problem, even if there slightly differently worn itll feel wierd and jump round the place, woudnt count on it causing the noise though..
