Title: Knocking/Clunking from rear when change gear?
Post by: peccy on September 03, 2004, 09:49:45 AM
i am getting a Knocking/Clunking type noise from the rear when change gear? especially at low revs when going slow, if change at high revs its not there.

sounds like the box / rear diff?

could it be a bit of play? anything to worry about?

cheers, peccy

Have you had the car long? Has this recently started or has it always been there as this is quite a common feature of certain uprated differentials. You may have an uprated diff.

Im pretty sure it has been there since I brought it about 6 months ago, I know it has got a twin plate HKS clutch on it, I don\'t think the diff has been uprated, is there any way of telling?

If you struggle to bring your car round on tight turns with your rear wheels \'ploughing\' then you have an uprated LSD
