Thanks for info, Simon!
Compressors are safer, no doubts. Anyway I don't like them always, as it is often hardly possible to avoid injuries of the spring coating.
Am I right supposing, that getting the stuff back in with the jack, the weight of the car is too less to compress the spring fully?
How about to "tie" the lower cross-tube of the suspension to the garage bottom (e.g. a screw with a ring anchored to the garage bottom)? Then it should not be a problem to compress the spring the last few milimeters to get the kingpin assembly in?
