Finally found some time to get under the car and check everything.
Tie rod bushes look like they've been changed to polybushes and are good both sides.
Subframe to body mountings are all solid.
Upper ball ball joints seem OK.
RH lower shocks absorber mounting bolt was loose (no idea how!) so I've tightened that and all seems OK now.
LH Track Control Arm looks to be the problem with a lot of movement on the inner bush. Tried to video but it's the wrong format for the site at the moment. Will have a play and see if I can upload it later.

I've loosened both bolts so good news there but can't quite get the subframe mounting bolt past the exhaust, so it looks like the box is going to have to come off and guess what.......
