Brad,
I found that the u-joints on my main driveshaft (propshaft
for those across the pond) had no noise or movement.
Howver, after removing the driveshaft to have it balanced I
discovered the u-joints were badly worn. Moving them by
hand while off the car, I could hear the needle bearings
grinding inside. They didn't move smoothly, but made jerky
movement, obviously requiring replacement.
I also found one of the grease zerks missing and a dry rusty
hole in the spider.
