drive train clonking

lockie said:

my tdi drives well(slowly see other post), its a 300TDI auto and there is a whining noise above 50mph and clonks when coming off the throttle, and when the autobox drops a gear.
The prop shafts appear o.k and I have grease them with normal LM grease. the stuff that came out of them was very dark, are they supposed to have C.V grease in the joints?

When you say propshafts do you mean the ujs?
I've just replaced one of my ujs, it clonked when it use to take up drive (manual) and a sort of vibrating rumbling noise. When i greased the sliding joints it pushed darker colour grease out but that's just because it's used. NLGI 2 grease is what should be put into the joints acording to my manual.

dunno about discos, but i had the same problem on me deepender and it was the A frame ball joint causing it.
