Well that is the best way i can think of describing it.

When, erm, making progress the rear axle seems to shunt as if its bushes are knackered when you change gear, erm, enthusiastically.

I presume there are rear subframe bushes, would these cause the problem and are they a bastard to fix?

Olly

Back end will feel 'floaty' if the rear subframe bushes are knackered - they can be a ball ache to replace.
Also check the rear trailing arm bushes and top mounts for the rear shocks.
If you need to replace either the subframe or trailing arm bushes, do them all at the same time.

If it does it when you change gear or are on/off the throttle, Id have a look at the rubber donut thingy between the gearbox and prop.

This.

Tell me more about this doughnut thing?

It connects the gearbox to the prop and acts as a kind of shock absorber for the driveline. If its knackered/loose there will be slack between the gearbox and prop.

thanks, is it easy to change?

Easy enough,more of a pita.

checked out the guibo and it doesn't look kneckered and the shunt feels to be coming from the back of the car.

Any ideas?

Jack one rear wheel up with the car in gear, then see how much the wheel rotates back and forth.
If its more than about half an inch then its probably due to wear in the drive train.

It'll require a bit more effort if you have a limited slip diff.
