what are the signs of wear.
Sorry I posted before finishing. I have a vibration which I think is coming from the front somewhere. I would liken the vibration to like a worn UJ joint on the prop shaft, but its not that. I have a new front propshaft. I checked the front wheel bearings by jacking it up and rocking the wheel. no signs of wear there. The vibration comes in around 50 mph and once I get up to 70 either I can't hear it or its not so bad. The wheels were balanced but I'm not sure if they did a good job as there machine couldn't really hand large wheels, I don't think its a wheel balancing problem, its not that sort of vibration. Its driving me nuts. any suggestions where I should look. I was wandering if a worn CV joint might be the cause. There is no knocking when I pull away or steer left or right.

CV joint wear sounds like balls pinging around a metal cage (cos thats basically whats happening), worse on full right or left lock.

To the best of my knowledge what your describing doesn't sound like a CV joint.

Ah, more details now.

Could be something as simple as loose bolts on the radius arms or panhard road.

I had exactly as your described, got under car, shook some things and all seemed fine started to nip up bolts with a spanner and the panhard bolt spun - horsed it up, took it for a test drive, vibration gone!
 
Cv doesn't cause much vibration really as its supported. It would almost certainly click around corners if it was going.

My first port of call would be balancing, then loose suspension components and steering, get a bar between joints and give them a wiggle. Mud insude tyres. Water inside tyres
