muddyjames:
I have a really really bad vibrating sensation going through the disco. It is worse when accelerating and especially at 30mph.

It doesnt happen when sat idling.

I have had a 4x4 landy specialst (that I wont be going back to as all they seemed to like saying was yeah, yeah, yeah, yeah, yeah) but they did mutter other words which was the prop shafts seem to be in good condition. So it isnt the UJ joints.

The only other possible clues which may be normal are.
Slight whining from somewhere. possibly from transfer box but not sure.
I put it into low range and drove in my close and if I was stationary then floored it it reved to 3000rpm but moved forward then whizzed up through the gears to 4th. I dont know if this is normal or not.

I am seriously hoping it isnt a transfer box or gear box as that would be a repair I certainly cant afford.

I am supposed to tow my caravan on friday week but at this rate I dont think it is going to happen :-(

I cant get hold of my nice landy mechanic, so come on mud clubbers whats your verdict.

G:
Is it lifted? Could be the rubber ring coupling (rear of the rear prop). Mine eats the rubber rings regularly and causes massive vibrations. The one i took of last time didn't look too bad until i got it off.
Or could be a binding caliper/warped disc.

Didn't quite understand this bit. If you floor it in low box it should (if it's anything like mine) move off pretty rapidly and move up through the gears quite quickly. G

Skibum346:
Have you had a clamber underneath yourself James?

It could be a really easy answer (UJ's) and it's easy to spot them. Basically, there should not movement between the components relative to each other in any plane (rotation, vertical or horizontal). If there is then that UJ will need replacement (and may be a sign the others are on their way out).

While you are underneath, try the same test on the diff flange (bit that goes into the diff form the prop shafts) again, looking for excesive play in any plane. If there is, your diff pinion bearing will be shot. It's a reatively straight forward DIY fix.

After that it could be swivel bearings, transfer box or I suppose gearbox but let's not get too despondant too fast eh?!

Let us know where your hat is at the moment and one of your local members I'm sure would be happy to pop over.

muddyjames:
It has standard height police spec shocks and springs.

Erm how else do I describe it. If you pul away in low range does yours accelerate really quickly in 1st gear? With mine it is like a clutch slipping as the engine revs to 3k with a very slow acceleration and then once at 3k revs it changes up through all 4 gears really quickly and off I go quickly too. Mine is an auto if thats a vital bit of the puzzle!

muddyjames:
I had a very quick crawl under and the prop shaft to each axle didnt move up or down and guy at "specialists in 4x4 especially land rovers" (cough cough yeah yeah yeah right) gave the prop shafts a pretty good wiggle as he was moving the disco back and forth (as much as it can in park anyway).

I am currently laying my hat just outside Daventry
