Installing Coil Springs Safely

What is the best method to install my new coil springs safely on my '78 Lemans? I searched the archives, and checked the commonly asked questions list in this forum, and didn't see any posts about this.

I have a quality coil spring compressor, which I used to remove the old springs. I have new Moog springs, a bit shorter than stock, ready to go into my freshly powdercoated control arms. The stored and potentially lethal energy in the springs when compressed scares the heck out of me, so I want to do this right.

Also, I am wondering how you can get the spring to sit flatly in the lower control arm? With the front of the car up on stands, the lower control arm will not be in a horizontal, or level, position during the install process. So, how can I get the spring into the LCA pocket when the LCA will be at an angle to the bottom of the spring? I hope I am explaining my question clearly.

I very much appreciate any help you can give.

Spring installation

First put the spring compressor on the new spring and compress it to approx the installed height..Don't worry it is adjustable..

Get your floor jack and your tools in a convenient spot so you can reach them..

place the coil in the upper spring pocket and raise the a-arm by hand until it contacts the lower end of the spring and then slide your floor jack under the a-arm..Pump the floor jack up until you can get the ball joint into the spindle and put the nut on and torque the ball joint nut down...

Then release the spring compressor and the lower end of the spring should just guide into the lower a-arm spring pocket...Remove the compressor and you are done..

Don't forget the cotter keys in the ball joint nut tho..

Should take about as long to do as for me to type all of this...

I have tried most all of it and now do what is known to work..

Also, when you compress the new spring, before installation, note that it will curve a little one way or the other as it is compressed. You can make the spring curve to your advantage so it meets the control arm at a easier angle.

As far as safety goes, handle the compressed spring gently, no banging on it with a hammer and don't drop it! Use lots of grease on the threads of the compressor.

Ok, thanks for the advice. It still scares me a little, but I have more info now than before I asked. OMT, I'm sure it'll take me longer to do each side than for you to type that unless you took 2 hours to type!

I am also wondering about "indexing" the spring, which I have heard guys talk about. What is that? Do you have to seat the top of spring in any particular way in the frame pocket, or just stick it up there? And finally, I know you aren't supposed to block that little drain hole in the LCA, but how can you make sure when you are doing all this that that tiny little hole won't be obstructed? Seems like you'd need to be able to finesse the spring's position to keep that hole clear.

Thanks for your patience. When confronted with a scary job, I tend to try and arm myself with as much info as possible prior to attemtping it.

The spring is "indexed" at the bottom.
The spring's pig tail end should be between the 2 holes in the LCA pocket.
