I rebuilt my MGB's transmission (4-synchro) about 9 years/90,000
miles ago.
Within the last week, it's developed a severe vibration. Shifts
great, clutch works. But at speed, there's a heavy vibration.
I looked underneath, suspecting u-joints (maybe 80,000 miles old). I
turned the driveshaft, and there was a lot of play -- but not in the
driveshaft. The transmission output shaft was moving maybe 1/8" side
to side. (also, some oil has been leaking out of the rear seal)
Questions:
Can this bearing be replaced without removing the transmission from
the car? Like I said, it's been a few years since I rebuilt the
gearbox. It looks like it's one nut and a circlip (once the
driveshaft is out), but it's probably more complicated than that.
Is it likely to have damaged other things in the gearbox? Like I
said, it still shifts fine.
Is 90,000 miles a short life for a bearing like this?
Your thoughts and comments appreciated.
