So I took my 04 Disco through some mud the other day, nothing too deep, but just to get a little mud on the tires, and now I've got a whine/squeel coming from underneath my car. I just replaced the u-joints in the front DS with servicable 1300's and am thinking that the cause of the problem is that I've washed the grease out of them....am I right on this or totally off? Anyone have any other ideas?
