Parts in between are the lower spindle support, mounted on the lower
outer trunnion, the wheel spindle, through which the kingpin assembly is
placed, the upper trunnion, attached to the upper loop in the kingpin================= I never use a spring compressor, I use nothing but the floor jack. I think a spring compressor is dangerous, it feels like you have nitro in your hands. First, I have a long, small welded link chain that I drop down the through the upper control arm, center of the spring and the lower control arm. Then connect the ends together with a clevis so that the chain is real loose. Next, jack the car up until you can put a jack stand, (or what ever you are using to block it up) under the center of the front crossmember, (and I only ever do one side at a time), with the bottom of the wheel about 3 inches off the ground. Next, with the jack handle sticking straight out of the front of the car, position the cupped jack pad right under the spring saddle on the lower control arm. Next, jack the lower control arm up until it is just STARTING to take the weight off that front crossmember jack stand. Next, take the wheel off then back the nut off the bottom of the king bolt, and leave the nut on with about three threads holding it on the king bolt. Finally, sloooooowly let the pressure off the jack to allow the lower control arm down until it just stops at the nut that you left on, while ALWAYS still maintaining contact on the jack pad. Take the nut off, then veeeery sloowly let the jack down until the lower control arm is free. About 90 % of them slide right off the king bolt easily. NOW, it might not just pop right down, sometimes it takes a whack from my BIG rubber dead-blow hammer or even a little heat, (remembering of course that you are using the spring to help push the king bolt off the lower control arm). The thing to watch is, never lower the cup on that floor jack so that it doesn't contact or have pressure on the lower control arm! Be careful, you are gonna have to drop it pretty far before it gives you an indication that it's coming off, Sometimes it makes a little "pop", sometimes it just slides off, and like I said, 9 times out of ten, they just slide right off. Watch carefully, if it gets to a place where it looks like the spring looks pretty stretched out and the lower control arm is pretty close to the floor but you still have contact and pressure on the jack, STOP, jack it up just a "titch" to maintain pressure but not push the spring up and go get the big dead-blow. Whack the king bolt somewhere on the body of the bolt and the fitting on the lower control arm where the king bolt goes into it. Do NOT hit the end of the king bolt where the bolt threads are. If you must use a BF metal hammer, use a short piece of two by four between the hammer and what ever you hit on the suspension. Remember, always lower it veeeery sloooooowly, always maintaining the contact between the jack and the bottom of the lower control arm. Oh! Have I mentioned that you always minimize the amount of your body in front of the wheel well that you're working in? Just think of it this way, only put what ever part in front of the wheel well that you won't miss too much if the spring DOES turn into a missile!
