Hi,
I am trying to find the source of an intermittent clunk in my 80 series. It seems to be from the driveline rear and happens occasionally when slowing down and turning right. I have kept the grease up to all uni's and slip joints and have new oil in both diffs and transfer case. I am starting to think it could be the 'floating' rear discs or brake pads. All uni's have been replaced last year and are still in good nic. It's an auto if that is of any help.
Thanks
Rob
PS> I am expecting a reply of 'wait till it breaks then you will know what it was'.

If it's coming from the rear when turning;
1. Is there anything loose in the back of the vehicle, jack, tyrelevers toolbox etc. I know it is obvious but!
2.
Check the rear
suspension bushes particularly those that locate the rear axle assembly. Wear there can cause all sorts of noises.
3.
Check for axle freeplay as it could be rear hub bearings on the way out.
Hope this helps.
Disco.

Disco,
Nothing loose in the back.
I have re greased the rear wheel bearings and adjusted to spec.
Could be the rear bushes as you mentioned. Similar noise to when you tap the disc with a hammer.more of a ting rather than a clunk...bit hard to describe.
It did it last night when slowing to a right hand turn under brakes, upon releasing brakes and just before accelerating round the roundabout a ting noise is heard...but then it may not do it for weeks....got me stuffed at the moment. I will get it on a hoist and
check those susp bushes.
Thanks again
Rob

can you initiate the clunk by manually changing down, that is, eliminating the auto change down?....just a thought
