version 7 sti rear diff knocking.....

[Guest]

I've had my v7 sti for about 2 years now, I've always noticed there's a small knocking sound coming from the rear diff when you slow down or take off, some one told me its normal for them to do that, is it ??

does any of your v7 stis do it?

is it a dull knocking noise?

most likely the are some flogged bushes on the diff carrier or t-frame letting the diff bump into things. not a big deal but fitting upgraded bushings certainly helps with handling

They are notorious for the rear hub nuts coming loose. Not loose enough to undo by hand, but enough for the CV to move in the hub. Back the nut off, lube the threads, and run it back on with a big grunty rattle gun. Make sure you tap the nut down into the locking groove too.

I had a knocking noise on my V9 from the rear diff/axle area when letting off/getting on the gas. Turned out to be loose axle nuts, Wingers charged around $250 to sort it out. I think theres a DIY writeup on one of the US forums, works out much cheaper.

Erm, isn't that what I said back in post #3...??

I get a ginormous BANG from the rear diff when I take off a bit briskly, or get a series of large knockings when the 'traction control' ie rear tyres activate during a slightly less than fully brisk take-off. The diff is hitting the underbody.
