update

Right wandering was control arm rear bushes fooked,changed and now mint but back to the rear beam.................

Still catching on drivers rear so took a gander, Wheel seems cambered in to much and catching arch liner so removed over xmas as killing tyre. There is no banging etc and drives perfect now and no play when jacked up

Thought maybe was just bad offset wheels so dug some spacers out of garage and whacked em on, FOOK ME she bangs now under braking,the whole back end jumps around and it feels as though the cars about to split in 2!! Still not actually jacked upand got under with a light but are beam bushes/mounts the 1st call of inspection then?? if the beam bearings are fooked surely there will be play. Any other ideas ppl
