The fronts are fairly easy to get off without destroying the ball joint. Hopefully you have a ball joint extractor and not just a ball joint fork. The rears - another story... I used this tool, and had no problem to get the front arms off without damage...

At 135,000 miles, and 22 years I would definitely replace the control arms if they are still the originals - the rubber is going to be hard / shot - or you could also remove the arms and replace the bushings in the arms with something stiffer given you track. If you choose to replace your control arms, I believe Meile is the OEM manufacturer... You can also tug on your tie rods once they are disconnected to see if they or your rack are wearing - there should be no wiggle. Note that if you replace your control arms you should also get an alignment... Also in the area you are disassembling are your shocks / springs - but you must have replaced those already if you are tracking the car. Only other advice - there is a clip and the bottom of the shock that holds the brake wear sensor. Don't be like me and forget to remove it before you pull the shock out of the hub.
