1999 Defender 110 Td5 SW Caledonian Blue

Clunking between gears and a rumble/vibration

Yesterday on the way to a rally, I picked up a clunk between gears and also at times what sounded like a stone caught in the brake discs.

Onwards to Kielder forest for the Pirrelli Rally.

Once moving the car felt OK when I got to about 45mph I can feel a vibration through the steering wheel. It was like driving of a rumble strip but not as harsh.
I suspect this is wheel balancing?

On the motorway, the car still had the rumble feel, certain speeds felt smoother than others, I think the sweet spot was around 58-60mph. Also going to check the wheel nuts.

Coming back down the gears on the A roads I got a clunk between the gears. I noticed that if I was a bit slower in the gear changing the clunk was reduced.

Checked the props and they felt OK for play, with the hand brake on I had a very slight movement in the rear prop and the front one felt OK as well. With the handbrake off there is some play in the front and rear diffs/transfercase, but not sure how much is too much.

I can liken it to something has stopped moving between gear changes and then starts again with a clunk.
Also discovered that I can get the same noise by backing off the go pedal and then back in it again quickly. 1999 Defender TD5 110

I check the A frame ball joint and there was only slight play. The noise to me sounds more central G/box Transfer case area? Any thoughts? 1999 Defender TD5 110

Two thoughts - I had a double carden failure that went quckly from a trittering/squeeking noise - caused the front prop to lock against the gearbox. Secondly - take a look at my post about the big nut coming loose on the transfer box to front prop flange - u/js fine but the flange can be moved by hand side to side - just tighten the nut - vibration at pretty much all speeds

Big nut on the front T/C output OK.
With prop removed clunk still there.
Onto the rear and found this. Does this look knackered to you ?

A new to be ordered me thinks. 1999 Defender TD5 110

Yep! That's proper f***ed Tommy! Replace the UJ, while you are at it replace the other end as well.

Lucky you found it in time..... I had one come apart on my old lightweight (although that might have had something to do with the V8 under the bonnet and my size 11's

To be honest whilst it is out you may as well replace the other end as well, it's already had 18months abuse and they aren't a fortune to change. Personally I would do it for peace of mind.

New prop UJs arrived today, So far not had much joy extracting the old UJs, Removed the cir-clips one on bit of the UJ the other cir-clips have broken off and left bits behind. Maybe I need a hydraulic press....
Tried the socket method to extract the UJ but despite swinging on the vice they ain't moved!! 1999 Defender TD5 110
