My g has started to shift really roughly, can anyone help. It is auto and I have heard it could be the vacuum lines?

This might help, if the symptoms sound the same

Cheers for that, just took it for a run again and now the diff red diff light is on and the abs light? Hopefully this is all related!

lol, it seems the problems get compounded. I'd check the diff oil reservoir (near the brake booster, closest to the fender, same side as washer fluid filler neck) the caps often crack, but I haven't heard of them leaking, but you should be able to check the level from there.
Oh wait, when you say diff light, do you mean the one above the ventilation controls, or in the instrument cluster? Two different things, if it's the one in the center console, the ABS is switched off (hence light comes on) when any of the diff locks are activated (yellow light = activation in progress, red = locked.

The diff was locked in! Did some reversing for a bit and it soon unlocked! However the car has just been taken on a 1000 mile journey and aparentely the abs light keeps coming on and off and the brakes are coming on and off by themselves!

I started to read your quiery with a g/box clonking problem ending in abs lights coming on intermitently.

Obviously you have more than one greamling.

The g/box clonk sounds like a faulty modulator valve, naturally, the vacuum line to it, should be checked first, even to the point of checking vacuum to the injector pump. It would be useful to have a vacuum gauge to make tests, otherwise I would recommend that a professsional checks this out for you.

As for the brakes applying themselves, you need to ascertain what is the cause? I would initially check the brake pedal does it push on to the servo rod by its own weight? Likely hood is very low probabilty. Are the front wheels bearings o.k.? I would go as far as dis-connecting the ABS electrics to isolate any fault that may eminate from this unit. Compare the results by re-connecting the ABS again. Does the fault dissapear and re-appear?

Check out the ABS relay, and finally, I would suspect the servo its self.

I have not answered how but, point to the sort of areas your problem could lie.

Contact me back on 'anarake@aol.com.' with more precise faults conditions and problems, hope fully we can work through this.
