I believe all Disco1's after 1994 have the rubber doughnuts.

If you need to replace it, be careful to recover the bearing on the spigot. It would not be at all unusual for it to have gone missing, in which case you will need to order a doughnut kit, rather than just a doughnut.

I'm not meaning to be funny, but you are looking in the right place??

At the front of the rear diff there is a drive flange, then the rubber doughnut which joins it to the propshaft.

If it's not there, what is in it's place, a UJ?

yes theres a u/j in its place.is this normal?

No - someone has upgraded it for you. Think yourself lucky.

Nowhere, you never had one.

Later models of V8 don't have a doughnut, thats will be 97 and 98 models I don't know about the 96 models but possiably them as well.

cheers matey thats the doughnut sorted

any idea about this transmission brake.i thought maybe its adjusted too tight and its lightly grabbing the transmission and stopping it being free,like i said the clunk is only there whilst in gear and light braking and not when neutral is selected with the car still moving

Check yer A Frame ball joint.

bart2181 · Apr 12, 2009

checked that earlier on mate and yes theres slight play,but would this cause a clunk when braking?has you,ve probably guessed im fairly new to these landrover clunks

Trewey · Apr 12, 2009

Yes it would cause a clunk on braking, but also on taking up the drive. You sure it don't do that too?
There shouldn't be any play in it anyway.

I have had the transmission brake stick on, but didn't give me a knock, I just had to roll underneath and readjusted the shoes.

With knocks/clunks it appears that all you can do is check all the usual suspects.
It's early days, someone hopefully will have had a similar symptoms and will let us know.

cheers lads thanks for replys im going to get a frame ball joint changed in the week its a starting point thanks

Apart from underneath can you place a direction on the noise? My 200tdi developed a clunk towards the OSF and it turned out to be the bushes on the radius arm to axle connection. I also had to have repair washers welded in on one side as it had worn the axle mounting lugs.
