Have a check of the prop shafts for play, you will need to jack up a wheel to check.

So just one wheel needs to be lifted off the ground is it brian. Should there be any movement at all ?
Thanks

I would lift a side if you can them you can check front and rear at same time there should be no noticeable play in the joints, and turning the lifted wheels may well help working out were the noise is coming from, others will know more than me on a sport.

Just make sure you use decent axle stands.

Drive shaft center bearing

Get underneath and check the center support for the Propshaft. It will thump on both acceleration and deceleration.
Start there first, then check the front and rear upper and lower arms for movement in the front and rear arm bushes. Then check the ball joints and the end of each suspension triangle.

Unfortunately it's a complete assembly.. Last one I did for a client came as a whole kit.
Front prop, bearing and rear prop all in one from island4x4 but check your first before throwing money at it.

You maybe can split it. As it was for a client I couldn't risk failing to split it and the rear most and formost uj's had stiffened right up.. No grease nippples
