Rear differential help

[TurboB3]

For a while now, my rear end has been having problems making noise. Its when I shift or sometimes just push in the clutch. Recently though, it sounded like a hammer hitting the bottom of the back seat as hard as you could hit it, but the thing is that noise lasts for a day or two, then goes away for a while.

It leaks so I am going to replace the seals. Does anyone know where to get the rear differential seals other than the dealer? Ive been looking for days.

Could be a good time to put a LSD

backlash and flex guibo and possibly diff mount.. mostly its improper gear backlash that causes the bang. dont necessarily need a new diff just a pro to reset it.

talk to koala motorsports, cool guys over there. have lots of diff stuff.

i would get under there and check out the guibo. its a common wear item and sometimes go bad sort of unexpectedly. if it does seem to be in peices, replace is and keep puttin along
