Anybody who has ever tried installing coil springs on a car with no engine in it knows that putting them in can be a real challenge due to the fact that there isn't enough weight to hold the front of the car down. Here is how you do it easily and safely.  Cool

#1  PREPARE YOUR WORK AREA
You want your control arms mounted to the frame and swinging freely. You want to have all your ball joints in and ready to go along with the nuts that go to them. You want your steering knuckles clean and ready to mount. You want to have a large chain to use as a safety chain. You will also need a coil spring compressor and a large socket wrench to turn it. Don't forget a floor jack and a pry bar.....and of course, those crazy coil springs. My coil spring compressor was purchased from National Parts Depot under part # 988-1 for $35.



#2   DROP IN THE COMPRESSOR AND MOUNT THE SPRING
A spring compressor usually comes with two ends that have hooks on them. One set of hooks slides freely up and down the long threaded rod and one actually screws onto the threaded rod. You need to remove the hooks that slide freely and set them aside. You want to use the hooks that screw up and down the rod.
Drop the threaded rod down through the upper shock hole in the subframe. Make sure you have a couple stout washers underneath the head of the bolt. Screw the threaded hooks onto the end of the rod.
If you are using the rubber spring isolators, attach them to the top of the spring now with plastic wire ties. Now mount the spring up into the subframe with the spring compressor going down through the center of the spring. Use the hooks to grab onto the spring at the lowest possible point. Make sure the threaded rod is centered in the spring. Make sure that the bottom end of the spring is rotated to the right spot so that when it's compressed it fits into the little pocket in the lower control arm correctly.  Now begin to tighten down the big long bolt just tight enough to hold the spring in. Once the spring is supported, use the safety chain to wrap through the bottom of the spring and around the subframe. This is a safety precaution just in case the spring compressor breaks or some other failure happens. These springs are very dangerous when compressed so do this EVERY time.




#3   COMPRESS THE SPRING
Once your safety chain is hooked up, you can begin to tighten the big threaded rod and compress the spring up into the subframe. Once you have it compressed enough to swing the control arm up high enough, attach the steering knuckle to the lower control arm ball joint. At this point you should slide the floor jack under the lower control arm and use it to hold the control arm tight against the bottom of the spring. Use a pry bar to pry the bottom of the spring into the spring pocket on the lower control arm. It will pry in very easily and pop right into place. Now use the floor jack to jack up the steering knuckle high enough to attach the upper ball joint. Once the ball joint nuts are tight, you can remove the safety chain.



#4 DECOMPRESS SPRING AND ADMIRE WORK
Once your ball joints are all attached and your steering knuckle is in and the safety chain is off, you can take out the floor jack and then loosen up the spring compressor to let the full tension of the spring out on the control arms. The spring compressor rod just pulls out the shock hole and the hooks just fall out the bottom hole. Pat yourself on the back....you got your coil springs in without maiming anybody!  Very Happy

What brand of internal spring compressor did you use ? I have broken 3 internal ones . and I bought a set of the external ones but the spring will not go up in the frame pocket with them on the outside. I have tried to do it as you have shown and the threaded nut strips out after I get about 2 3/4 inches compressed . I have tried to compress the spring as shown by the tool maker with both coil ends on , and as soon as i get down to around 3 inches it broke . I need to get them compressed down from 16 inches to about 12 1/2 to fit in . The motor is out of the car so I can't use any jack under the a arm method .  I'm starting to wonder if the springs are to stiff.   I purchased them new from Ames and they were made by moog for a 78 with a/c , and with performance suspension (WS6) .The springs are about a half inch longer than the old ones , have the same outside diameter , the same coil thickness .  But the new ones have one extra wrap of coil versus the old .

i used the spring compressor from napa and it worked realy well. Thank you for the post. It saved me alot of time and headache. My springs were only compressed down to 14 inchesand pry in the rest of the way.

Great info, but I wish I would have known about this last year when I did the suspension on my 71. Installing the coil springs was by far the most p.i.t.a. part of the install. I did it the old fashion way by compressing the spring with the same spring compressor you have but hoping the spring would not kill me! I also did not have the motor (or any front end sheet metal) in the car so the car would raise if I used the floor jack method.

Again, great post!

just had to say, great advice! im currently restoring my 1970 lemans sport and was kind of worried about installing the front springs. i was able to rent for free a coil spring compresser (thanks to living in a small town) and installed them just like you said. i did have the motor and trans in the car so that helped with the spindle install, but it still would have worked without it. i was able to get them in by myself, and yes without killing me! thanks for helping us shade tree mechanics and now my car is ready to rock!

Great info Jason. I would like to share a tip that I used when I installed my springs. Instead of prying the spring into the lower control arm and using a floor jack, I used a couple of ratchet straps. One was hooked onto one of the lower coils and to the opposite side of the subframe and the other was on the lower control arm to the upper control arm once the spring was in position on the lower control arm. As I compressed the spring I tightened the ratchet strap attached to the spring to keep it inline with the lower control arm. Once the spring was compressed and the ball joints lined up the other strap was tightened to bring everything together. Worked like a charm!

Few questions:
how hard is this exact method with the inner and outer fender still on?

also say i didnt use a compressor (my engine is in also) could one use the jack method with a safety chain of course to remove the springs?? Basicly when the lower arm (LCA) is supported and unbolted from the spindle (at the ball joint) does the LCA swing down far enoght to let the spring come out without it being compressed 1st?

I admire the amount of safety used in the pix and this tread. I was no where near as cautious when I did the springs in my 75 and 76, looking back I guess I should have been safer then using a gorilla bar and letting the springs fly(won't even mention the beer). I did however use the correct compression tool. I'm glad to see a safe instructive proceedure on removal and installation of coil springs.

Installed both springs today in under 30 minutes, worked great, thanks for saving me grief. It's unreal how that shaft just fits in that hole, like it was made for it. I also used a plastic washer under the steel washer on the top so it didn't scratch the subframe at all. I did a 69 Camaro a few years back, and I don't think the hole was big enough to do it this way, and man was that rough. Thanks Jason, great stuff.

I tried it this way just the other day and wow, it was so much easier than the prybar and dual spring compressors... great tip  and use the strap too, just not the small one in the pic... use a big one as these things are under pressure

I just used this method last night.  It work very well!!  Best $35.00 I have spent yet.  I used the jack to lift the lower control arm and the spring popped into the pocket.

Same way, but reverse order, I just did this on my car. Put the bottom arms on the spring about 2 coils from the bottom so when you decompress the spring, it should be out of compression when the jaws reach the end of the 'jack screw'.

I would also buy some decent grade 8 washers for the jack screw. The ones that came with it are cheap and mine tore up.

Honestly, I don't recommend removing them the way I did.   Any hoo, I used an 8 foot section of rebar and threaded it down through the shock mounts in the frame and the lower control arm.  The car was in the air a few feet and the front clip & motor were removed.  I chained the spring to the frame & lower a-arm.  I stood inside the frame and removed the lower ball joint nut.  I believe I used a ball joint puller and seperated the ball joint with a long extension and a long handled ratchet.  It made a lot of noise when they popped but no drama.  The chain and rebar combo restricted the spring's motion.  It helped that there had been a coil cut off & flattened previously so the spring length (potential) wasn't as long.   Again I was in a hurry to pull the front end apart, it was late and I didn't have access to a spring compressor.  Stupid?  Yes.   Don't do it.

Ok, getting ready to do this in about an hour, here are the steps I'm thinking

Removal:
chain on spring
install spring compressor, tension lightly
jack under a-arm
break ball joint
slowly lower a-arm - drop
spring is still tight against top - slowly loosen compression tool.
remove spring

Sound about right?

Don't know why I'm so nervous...

sounds good...make sure that safety chain is in there and wrapped around the chassis. Watch your fingers, use pry bars if you need to, do not get your hands near these things......

Good info. I'll know what to do when I put them back in. To get them out I removed the ball joint nuts and then whacked the outside of the upper ball joint portion of the spindle a couple of times and it let loose with a bang. Spring still can't get out though. I then used one part of the spring compressors that fit on the out side of the spring to compress it enough to slide it out. Gets the adrenaline moving, just stand inside the subframe and the spring can't get you. LOL

Yep! The springs in my 70 wouldn't come out without compressing them even with the LCA all the way down. I won't be doing it that way again though! Smile
