When you put the new ones in the Front, make sure the Springs Pigtail sits inbetween the 2 Holes that are in the A Arms Spring Pocket.
Thats the best advice yet. The very first time I lowered something (a long time ago) I didn't know anything about that. Ended up having to do it twice.
I have used the spring compressors (rented), jacks and ratchet straps.
The spring compressor main bolt stripped out and made the spring bounce around inside the fender for a few seconds.
The jack worked great as long as u have a good quality jack with a wide base that won't tip over and take your time and be very carefull.
The ratchet straps were great but a little trickey to position correctly so you could get it back out w/o cutting it.
The above suggestion to use the hose clamps (multiple of course) is what I will try when I replace the springs on the new project.
Overall, a pretty simple task as long as you have the tools and some patience, common sense doesn't hurt to stay safe. Best bet, when removing the spring once u get the jack all the way down, use the longest pry bar u can find to get the spring the rest of the way out. It will have some pressure to it but not enough to shoot out. I will pop and scare the chit out of u, but not go anywhere. Just watch ur fingers.
This is in my opinion hardest on foxes. SN cars, especially new edges have more room and are much easier to do springs on. Maybe it just easier b/c the new edge's are newer and the bolts don't have 20 years of chit on them.
Just my 2 cents from many past experiences. Don't be afraid of it, pretty simple job. Don't forget to get the car alligned after.
