Ok my v8 disco has covered 180k miles, and there's a vibration, not unexpected I guess.

All seems fine at 60mph but 65+ the thing feels like its going to shake itself to bits.. and lets face it, it might well do that, the vibration is through the body/floor not really the steering.

I'm going to check tyre pressures and wheel balance but once that comes back fine and its still shaking to bits.. which I can tell it will.. I'll need some help.

Could you help with some things to check that could cause this, but more importantly, how to check them? iv changed cv joints on normal cars but never worked on the heavy 4x4 drive train on a land rover.

Ideally I'm hoping for things I can check without lifting the car more than 1 corner at a time and things that wont require pulling it apart too much.

Any help would be appreciated. I have a workshop manual and a stack of tools but not sure where to start looking.

P.S. You may have noticed a few threads about my disco, seems i have inadvertently bought a project car :eek:

check out yer prop shaft UJ's sounds like thats yer problem
 
Could you give me some idea on what im looking for? the best way to check them?

block the wheels so it dont runnover you , take it out of gear and handbreak off .
on the ends of the props the uj's are just twist the prop and watch the cross bit between the 2 parts of the joint if there is any movement between the 2 parts and the cross piece thats your problem
 
Hopefully a wheel balance will sort it :)
I had a similar problem but at lower speeds (55) which was the coil packs and leads failing. once the torque converter locked the engine was under a heavier load and the poor spark caused the vibration as it was only running on 5 1/2 at low speed you didn't notice it , only under load.
 
i haven't yet had time to get the wheels balanced, noticed today that its does it when off the throttle to so may well be just the wheel balancing *fingers crossed*
 
wellllll i think i have found the cause, after checking the tyre pressures and still having the issue i popped it into the tyre shop to balance the wheels, and the guy showed me the tyre spinning on the machine... seems the very dodgy remoulds are out of shape, could see the thing wobbling all over, explains everything, needing 4 new tyres it would seem :(

I've even known new tyres do that occasionally. Still - good job you found out. Better safe than dead.
