Removing Coil Springs from subframe

I've been given a subframe for parts, and need to remove the coil springs to get the LCA and UCA out. I've done this before - but when everything was still on the car, and I used a floor jack to raise the LCA upwards slightly, then loosened the castle nut from the steering knuckle and lowered away on the jack, undoing the nut further as I went, until the coil was fully unloaded. Also had a safety chain through the coil spring.
When you don't have the weight of the car to jack upwards against (i.e. the subframe is removed from the car), is there a safe way of removing the springs? Is a pair of spring compressors the way to go?

Re: Removing Coil Springs from subframe

Thanks Mike - so basically you use the threaded rod and nuts/washers each end to slightly compress the coil spring, then once the tension is on that (rather than on the steering knuckle), you can undo the castle nuts on the ball joint and gradually loosen off the nuts on the threaded rod until the spring is unloaded? Neat, I like it! Thanks again

Wrap some rope or chain around the spring and frame just for good safety measure.

I run the all thread in until I've slightly compressed the spring, let off a bit, loosen the castle nuts about 1/4" to 1/2" (but still fully on the ball joint threads) and then beat the living #$^@# out of the ball joint to spindle connection with a pickle fork. I like to have the ball joint to spindle connection under spring tension so you can hear it pop when it loosens. Once both ball joint studs are loose from the spindle, you can unthread the all-thread and remove the spring.

Make sure you have enough extra length on the all-thread to allow you to fully decompress the spring. Remember that the spring fully decompressed will be an easy 6" longer. I'd recommend at least 18" of extra length. I use the all-thread in the original 4' to 5' length. Installation is just the reverse.

I'm as safe as the next guy, but I see no need for a separate chain or other spring retention device with the spring held in place with a piece of 5/8" all-thread.

Re: Removing Coil Springs from subframe

Unless the all-thread decides to let loose.
I wouldn't trust it as far as I could throw it.

Re: Removing Coil Springs from subframe

I've found the best way to separate the ball joints from the spindle is not with the fork method, but with a (large) brass hammer smacking the side of the spindle where the tapered fit is. With spring tension on the spindle, nuts loose about a 1/4" but in place and the threaded rod attached of course, ready to catch the separating control arm should the nut come off, smack the side of the spindle and the taper will pop not harming the rubber boot as the fork usually does..
