Have you looked at your rear trailing arm bushes yet Reggit ?

I did mine last weekend, not easy on your driveway ! They literally fell apart when I unbolted the old ones.
And changed the lower rear tie bars, difficult as the outboard bolts were seized in the bushes, one came out with a bit of force, the other I had to cut off with a cutting disk on my angle grinder.

I also changed all four springs (Eibach -30mm) and all four shocks (Bilstein B4) - the steering / handling is noticeably improved, they were all shot at 118,000 miles.
