Bongo Fury

I have had the same with mine,after the garage had a look to see if my brake pads needed changing,aftre that she (yes mines a girl) shook 65-70,had them re-balanced and no better at all had drop links done tyers look fine,so should i be worried about the prop shaft

No - if the propshaft goes, you'll probably notice the whole van shaking.

I seem to recall reading somewhere on here that the bongo wheels should be balanced "in situ" whilst fitted to the vehicle? Should the tyre fitting place have such a specialist device of course.
