Does it feel like the engine? Mine has a similar fault, but it feels more like its running on 3 cylinders.

Also not all the time, can be great one day then not so great the next.

I have started to avoid supermarket fuel which seems to help.

No it doesnt feel like the engine it feels like something is out of balance,its fine when you back off or going down a hill.

prop or output shaft. most likely prop when you say you've checked em. was vehicle in neutral with handbrake off?? and have you checked that they're well greased. ??

Ye checked them in neutral with the handbrake off and there wasnt any play and looked well greased but i will grease them and see if there is any difference, is the output shaft the one that comes out the transfer box to the prop and is it a big job?

You need to take the propshafts off to check the uj's properly sounds like one is starting to sieze up.

I just did my tappets and that smoothed out my Discovery no end.
They were a bloody mile out, one valve cap missing and one turned into a polo.

Did the engine sound noisy or was it just running rough?

The engine sounds fine but does lack a bit power.
