Started as a slight clunk when going from R to D but only occasionally checked the Unis but they appeared to be tight - this was about 4 weeks ago. A couple of weeks ago it started to make a squealing sound around the 2000rpm like a loose fan belt or a bearing going bad in the engine compartment. I could only hear it when driving, and under load, if sitting still and revved the engine you could not hear it.
Finally crawled under it to adjust the hand brake and had a look around and saw the uni almost hanging out.
Now to put the prop shaft back in tonight - that will be fun by torch light!
