I took my propshaft out last autumn, and never got round to replacing it (with the re-con vcu and bearings I bought) and even though we've had no bad weather it's been great in sub-zero conditions, where workmates have complained of their cars slipping about on the road.
The prop assembly's not too heavy (I thought I saw someone say 25kilos), but the manuals say not to put too much of an angle on the joints, so what I intend doing before replacement, is to make up a wooden jig to hold the thing, nothing fancy, just a plank of wood with some uprights with 'V' cuts to hold it steady.
