Drove it a few days to work and back last week, about 130 miles total, mixed driving. Probably will again this week if weather warms up more.

Grumbling, minor pulsating vibration is still there. Can feel in throttle and steering wheel, in the area of the transmission or very front of driveshaft. Still mostly perceptible in the throttle float zone when cruising above 55mph. Not really discernable during acceleration. Can feel some of it when I push in the clutch at highway speed.

Driveline angles are essentially in line, with the slip yoke off maybe .15-.25° compared to the rear yoke at most. Certainly feeling that it is more likely that the source of what I am feeling from the rear of the transmission, more specifically the tailshaft bushing. There is a bit of side to side play.

The transmission is in need of a refreshing soon to begin with, since it is a leaker from the speedometer gear area.
