Add to the shopping list,
1 kg minced meat
2 rolls of glad wrap
12 banannas
bag of sawdust
8 pairs of pantyhose.

If you cant get the jagman to repair what you paid $1900 for try the above ingredients in no particular order.

By 60 K's did you mean 60,000 kms or just 60 kms?

If the tailshaft angle was extreme enough to be causing the problem I am sure you would feel it wobbling/ trying to drive overcentre when going slow. Even then it would have to be really extreme to put stupid load on the diff pinion which just cant happen normally with a slip yoke.

Will be interesting to see what you pin down as the cause.
Good luck with it.
