    Use a gear wrench on it and the process is quick, easy and safe. Pretty much the same design that is in the factory manual.
    The tool I like allows a impact wrench to be used to through the top (with the shock tower cap removed). I think this beats the heck out of cranking a gear wrench or whatever between the turns of the coil.

    Now you're talking! IMO, this is the right way regardless of whether you elect to use the single set of hooks and fork type or the double set of hooks type.

    You should "never" use an impact wrench on a spring compressor or gear puller. Turn it the opposite way and using a socket and ratchet thru the shock tower hole is OK. The only down fall is it is hard to fit the plate up high enough in the top of the spring to grab enough coils to compress it down for removal. It works for Mark with the short coil springs. fficeffice" />

    In my experience this is the best way to use this tool. (fork at the top and turn from between cols) If you put the fork at the top there is a possibility of bottoming out the threaded shaft on the spring perch then you have to undo everything then reposition the tool and start over.

    Original tool had a ball on the end that engaged the fork at the bottom. Then the tool was turned from the shock hole at the top of the spring tower.

    OK, more fuel for the fire. Besides expensive, what about this one?

    Re: How to? Front Coil spring compression?

    Well went to work today on installing the springs. Ended up going to Autozone and renting one of the ones in the red plastic box. Leaned a few lessons and it took me all day up till eight o:clock tonight to get one spring installed! My arm and shoulder are killing me. Using an open end wrench to boot. I tried to position the compressor so that I could turn it from the shock tower opening. No go. bolt would extend to far down into the spring seat. Ended up compressing and un compressing the spring five times before I got it right. Then found out there was to much friction to loosen it once I had it on the car. Off it came and I struggled to get the compressor back off. Then I greased the heck out of the bolt and the washers at the bolt head. One more time. Springs are seventeen and a half inches un compressed. Had to compress it down to eleven and a half to get it in. The last time with the help of a socket and extension on the fork to hold it I got it in place and released the compressor. If my arm is up to it I will do the other one tomorrow. should only take a couple hours or less this time. If I thought I would have to do this over I would invest in a tool that worked through the shock opening definitely!

    Al that one is expensive. It looks safe and long enough to work through the top though. I like it.

    With the right tool, this is a 20 minute job.

    As bob stated, it's a 20 minute job at best. Get a gear wrench and it speeds up the use of the tool. I'm sure you have now experience how hard it is to get a socket and ratchet in there. Using a box end wrench just takes way too long. I'll be removing the springs on a 67 Cougar project next week. Maybe it's time to make a short video of the process.fficeffice" />

    Re: How to? Front Coil spring compression?

    I found that if you jack on the LCA just a little at a time, it makes turning the bolt much easier. Key word is "just a little at a time". I found that by keping the LCA supported, it seemed like there would be less of a liklihood of that thing flying out. I mean, thats almost what you have to do once you get a little compression on the spring. Once you get it compressed beyond the point where it is touching the seats, it get harder and harder to tighten/loosen the spring cmopressor. If you dont put tension on the LCA, you are fighting a battle keeping the spring in place when you are tightening/loosening the spring compressor.

    I agree..20 minute job..tops.

    Re: How to? Front Coil spring compression?

    People have brought up a few points.

    "I tried to position the compressor so that I could turn it from the shock tower opening. No go. bolt would extend to far down into the spring seat."

    I did cut the end down a bit as I recall, so it did not hit the spring seat.


    "Springs are seventeen and a half inches un compressed. Had to compress it down to eleven and a half to get it in."

    What springs are these? The books I have show most springs at 14' to 15" " free height. I have used the MOOG 8356 with good results. 10.5 loaded 15.036 free height.

    No wonder your having a few issues w/ all this!

    Safety note: You should install hose clamps on the spring either side of the fingers. This will keep the finger from moving during compress/un-compress. MOST important when installing new springs- painted & slippery!

    Again hope this helps!

    This style is the only one you should use in my opinion. We will have a like compressor on our site that you can borrow for free when you buy front end components from us, we will also have them for sale next week. Watch this video to see how easy and safe they are to use.

    Re: How to? Front Coil spring compression?

    A day late Don. I got the second spring on today. Still took me a while. About an hour using an open end wrench to turn the compressor....Boy is my should sore! The springs are original from a 68 XR7 with 390 and air conditioning. I didn't want the compressor forks to move or scratch the springs. I had an old piece of fire hose witch is canvas on the outside and rubber on the inside that I put between the fork and hooks and the spring. This worked out very well and it never walked around on me. Can't imagine doing one of these in 20 minutes without power tools!
