    weird noise, sounds like a rattling bearing.

    hey all, searched and searched and couldnt find anything close to what my e30 318i manual trans is going.

    my gearbox makes a high pitched scratchy noise, kind of like a bearing grinding, its not constant it comes and goes.
    does it in all gears/neutral
    putting the clutch in doesnt do change anything.
    only when the motor is hot and im coasting 30+ mph

    1985 318i
    clutch feels good, all the gears shift good, never grinds while shifting.
    could it be the CSB failing? guibo? im going to start taking it apart today
    just wondering before hand if anybody dealt with this. thanks !

      I had a similar experience with a failing (new out of box junk) CSB once. After a huge headache I was pleased at the cheap fix!
