Hi Keith [my middle name by the way]
best way is to jack her up high, place some floor stands or big wooden blocks under the body, just in front of the bolt that fastens the lower control arm to the body..loosen/crack the the wheel nuts before you jack her up, because you need to remove both back wheels. Once you have her up and safe enough to crawl under and apply a bit of muscle to all the joining points..use a pinch bar or similar on every moving joint [seven of them]. One of the most common is the ball joint on the upper control arm, where it connects to the top of the diff housing..if the rubber boot shows any sign of contact wear or the joint itself moves about..replace it. It's around 70 pounds for a Crown brand, which I find very good. Any of the bushings in the other areas which show signs of wear[movement] are around 16 quid each. If you are into serious off roading activities [I'm not] then you will pay a lot more for these replacement parts, but I use Raybestos bushes and Crown parts whenever I need them and get a very good result from both brands. When you get to stage of deciding what you might need, just give me a PM and I'll point you in the right direction for parts..all in the UK.
Just make sure the vehicle is solid on the jack or blocks BEFORE you crawl under there and start wriggling around.
