Hi All
Have a clunk in the rear of my 99 ser 11 Disco. I only get it with a load on, like a couple of heavy blokes in the back and some luggage, or a box trailer with a load of soil.
First noticed it while going over some rolling bumps (wide high corrogations) leading on to a sandhill at a slow speed. Have looked underneath and can't see anythink obviously wrong with bushes ect.
Thinking possibly a shocky problem?
BTW it doesn't have a ride leveller.
Thanks
Casey

Clunk in rear of Disco

I agree.
If the ball joint is stuffed, check the arm to chassis bushes.
I recently replaced the ball joint, only to find these bushes were stuffed. Will fix them soon
As an aside, my replacement ball joint cost $90, but I had to press it from the housing. What a pain, even with a 10 ton press.
I later found out that a replacement ball joint including housing is $120. Go for that method.

It hasn't got an A-frame under there. 
Does it make the noise when you do change in direction turns? It seems increasingly the Watts linkage bushes are wearing the plastic inserts in them, especially the upper bush. Also if you have ACE this can do it sometimes also. Its probably also worth checking the chassis for looseness and any cracks

Hi All
The noise is there when the rear gets a bounce up like when going over slow steep corrugations, so as the rear bounces you get a clunk in rythmn to the bounce.
The other time I hear it is when I have a trailer on and it sounds like the hitch is clunking on the ball, the type of noise you sometimes get when the trailer is empty.
It only happens when I have a load on, eg: several people on board or when towing a loaded trailer.
Something that has just come to mind, when towing the clunk is there constantly and has nothing to do with the bounce.
I will further investigate as soon as I am able and let you all know, but at the moment there is nothing obvious by looking, I plan on getting under with a bar and see if I can detect any movement that way.
Cheers

Shock Rubbers?
Or don't they have them either (I just can't keep up with these modern vehicles with all the gizmos).

I just had another thought on this .
The trailing arms on the rear axle of a Disco 2 are like the leading arms.They are mounted to the axle by 2 bushes under the axle. The front of Rangies clunks if the bolts through the bushes are loose.
the bolts should be BLOODY TIGHT as the centre sleeve should be locked to the mount.

Hi All
Just been under the Disco with a large screw driver and everything seems OK, no movement in any of the bushes and the body mounts look OK as well. I haven't put a spanner on the trailing arms bolts as yet but will give it a go. The only thing that I can see that may be suspect is the left rear upper shocky bush, the shocky has a slightly off angle to mounting pin look to it.
Next time I go down the beach I will take the towbar hitch out, other than that I guess it will have to go in to the local 4x4 shop, maybe I will pull the shockies out and check them first.
Just had a thought, a half a dozen mates, on the back jumping up and down with the skinny one underneath, Hmmm, I wonder!
Thanks to every one,
Cheers Casey
