took my 110 into local quarry for a bit of fun on sat, sat afternoon when driving im getting a clunk sound, i think its play in prop shaft but im not getting any feed back just the sound, also when pulling away there a whirring sound from front nearside im buggered if i can see anything, it runs fine but the clunk is worrying as it sounds expensive, any ideas?

you will have to jack each wheel up in turn and check wheel bearings swivels ,you can feel play in diff and cvs etc ,diff flange should have no end float ,prop ujs ,hand brake etc
