No compressor. no long bolts, no special tools.
I know the tricks too /ubbthreads/images/graemlins/smile.gif
Jack up the car sort of high, remove the road wheels, Unbolt and support the calipers, don't let them hang by their hoses,
Unbolt the steering arms, or pop off the tie rod ends.
Now unbolt the top shock trunion nut, raise the trunion clear of the king pin and pivot the king pin down as far as possible.
Have a friend hold back on the body of the car, remember it's jacked up quite high, sit on the floor, place your foot on the car frame, grab the spring with your hand and pop it out. It goes back in with a kick of your foot.
As long as the A arm is as far down as possible, the spring has hardly any tension on it. But pulling it out by hand while bracing yourself against a jacked up light weight car could push the car off the stands, this is the only serious concern. I do this all the time. I have removed a spring in a parking lot due to a broken A arm this way, others have seen it.
