Anyone ever use the strut compressors that are 2 piece and independently compress the spring. I've used the wall mount style when I worked in a shop but never these. I've heard the horror stories of these flying around shops and decapitating people etc.



I've got to do rear struts on the old lady's car and everyone is asking 600$ plus which I think is nuts.



Recommendations? Warnings?

Be careful with them. I've used them a couple of times, and I can easily see how they would come loose.

Go to AutoZone or Advance , and they'll rent you the compressor for free(they cahrge your credit card, but refund the charge when you return the tool).  It's been awhile, but I remember the compressor I rented from Advance was pretty stout and compressed the spring easily.  At the very least, you'll be able to check it out before you rent it.

If you use them correctly, they are safe and work fine. I've used the one's from Autozone before with no issues several times.

for added insurance when using the compressor use a ratchet strap or 2. in the event the compressor or spring slips
this will prevent your compressor or springs from becoming missles.
if your renting the tool
make sure it is in good condition one worn corner or bad threads can result in some serious accidents when under that kind of pressure.
was witness to a  spring almost take a guy's nose clean off. and knew of a guy that took a strut to the chest.

follow these 4 rules
1. dont get in a hurry
2. keep your fingers clear
3. slow and steady dont jerk around on it.
4. bigger hammer rule does not apply here

When I had a VW I made my own set from tow pieces of allthread, four nuts and some old leaf spring.



Worked like a champ.







Now Autozone will loan/rent them to you.

not a great fan of those; i've used the wallmount shop ones and they are safer


i'd even go to a shop and offer the guy 10 bucks to spring up the shocks

I have a set of suicide sticks.  Used them a couple of time w/out drama.  Don't be stupid & you'll be fine.

ETA:  They work best with an impact gun.  If you're thinking of using hand tools to crank them down, take the parts to a shop & pay $20 to get the springs swapped.

Ditto on the impact gun.  Twisting and pulling with a ratchet can cause things to slip loose.

make sure they are exactly 180 degrees from each other on opposite sides of the springs.

make sure you use the retainer pins so that it cant jump off.

as you tighten down each side, make sure not to let one side get too far compressed than the other, try to keep it kinda even, a little on one, then a little on the other, so the spring doesnt get all crooked and pop off in your face.

watch fingers and wear eye pro.
