Larry,

If you have B'laster (and I hope you do)... I'd spray the large retaining glan nuts located inside the coil spring at the top of the strut tube a couple of times a day ... a few days in advance. Those SOBs can really be tough to break loose if corrosion has welded them to the top of the tube. Be careful with the spring compressor ... crank each side down evenly a bit at a time ... make sure everything stays in place ... if the compressor comes loose ... or breaks (don't use a cheap tool here) you could end up in the ER or worse. Don't remove the top strut nut until the spring is compressed enough to take all the force off the top cap.I hope you have Bentley or Haynes manual for reference. Good luck. Be careful.
