I've experienced this 1st hand in my 98 5-speed. The tranny didn't
fail, just got incredibly noisy. When I replaced the clutch at 140K
miles, I also replaced the differential bearings and all was good.

Was the issue fixed in the 2000 thru 2001 5-speed manual trannies? I
remember the Nissan brochure boasting stronger gears in the manual
tranny compared to the 99s and below.
