    Rear differential rebuild?

    I did some internal swap in my rear differential, and now it's making a whirring noise.. so it looks like I fubar'd the shims. Anyone know any shops around here that can overhaul differentials?

    damnit

    superior driveline on north ave (near you) is supposed to be quite good. call 'em up... see if they'll help out.

    However, consider that you are using the bearings from the j30 diff with unknown miles. it could be a bearing issue, not a shim issue

    you think bad bearings would cause that awful whirring noise? it's speed dependant

    Bearings could, but I'd wager on shim issues/gears not aligned properly. Check out multistate transmissions on ogden in naperville (across from Gerald nissan), ask for Chris Jennings, and tell him I sent you.

    Did you put LSD-specific fluid in (stupid question?)

    doesn't need it, since the limited slip portion is sealed

    Sounds like you didnt check the for proper tolerances on the diff. I know Touge Factory used to install diff internals, but as far as overhaul you have to find a good shop that specializes in it.

    actual diff overhauling is not that hard. Just need to know the specs and know how to read painted gears.

    I accept bench work (meaning bring me the rear end and I will set it up )

    My poor dial indicator has not seen action in quite some time.
