Noise was getting worse and worse, then today, coming up a steep hill I got a knocking sound !
I thought great, at least now I know its the center bearing on the propshaft, even though it didn't seem to be in a bad condition.
So, this afternoon, slipped under the van and took the propshaft off. The bearing looks and feels fine, even the rubber doesn't seem to be perished at all.
I don't know what to do now
Also this propshaft doesn't have a UJ behind where the bearing is, its a joint thats got a sort of casing around, fastened up by allen bolts (not a rubber GUIBO joint)
I fancy changing the propshaft, I think the UJ's at the front and back are a bit dry and tired.
I just hope that the problem isn't in the diff
