Problem

[Guest houghton]

i have a citreon ax and it has a problem it has a lean towards the rear back drivers side.plus when you start to drive it the body drops very low over the wheel and when you stop the body goes back up again.but on the passenger side it does not drop.it has shockers on the rear not springs.so if their is anybody who has a ax could they tell me if they have had the problem or is it something that goes wrong with the ax.it is a m reg vehicle.i have had it to two mot stations and they say that there is nothing wrong with it.but you can see it leaning to the back right.so can anybody tell me what the cause is cause i wont drive it.the passenger side does not drop but i have noticed that it has dropped a bit.thank you.
