So it begins...
Search my posts on vibration; it's expensive.
Driveshaft sux. 2 pieces, glued together with RTV.
Goes bad due to driving fast. Over 70 driving for long periods killed mine.
Eats differential gear/bearings.
Eats Transmission tailshaft bushing. Tranny Leaks like a b.
So I end up:
Replace transmission. (these trannys do not like being constantly low on fluid)
If it just started
, get a new driveshaft ASAP. 93 Mark VIII ONE-PIECE or aftermarket. I have Aluminum shafts on both my cars.
If you are a TCCOA Member, there is a group buy going on, I think.
Something I noticed recently: The wheel bearings I replaced this year had this weird ripple on the bearing races; they were good, but sloppy. It looked like the same wavy pattern as on the Diff gears; Not sure if related or not.
