these things scare the begebus out of me. I've restored cars and have no issues working on any part of a car but struts, i'll leave it to the pros.

I've even taken the struts off and took them to a garage to replace the bearing for me and watching the mechanic use one of these gets my stomach in knots. even watching that video i had to turn away

Used these many times. Of course point the spring strategically when it’s compressed (I.e not towards you). I do add small “ubolts” to prevent the hook part of the compressing tool from sliding down on the spring as an extra safety.

To replace the strut, the spring needs to be compressed release the pressure from the big nut on top. Then the strut mount and spring can be removed and the strut replaced. Since the spring is intended to carry the weight of the car, it takes a lot of force to compress, even slightly. If that stored energy is released suddenly, it can do major damage

Lol reminds me of the time my mechanically-experienced friend took a look at my vehicle and told me someone "stole my springs!" since he couldn't see them on the struts.

Actually that vehicle had a modified MacPherson strut system where the springs are positioned between the lower control arm and vehicle frame, not attached to the struts.

In the dealership I work in, no mechanic uses the wall mounted spring compressor. The 6 mechanics I work with uses this type of spring compressor when changing struts, springs etc.

Hi everyone. What brand of full strut assembly would you recommend. I installed Monroes a few years ago and was not impressed. Have to replace the rears now.

Thanks!

We're the opposite. We only use the floor model. Though I do have a set of spring compressors similar to this and must have put about 200+ sets through them over the years. Even had to weld a new nut on one after the end gave out.

I wouldn't recommend the average diy'er use one of these though. Saving yourself 60 bucks isnt worth the risk of crushing your fingers, knocking your teeth out or worse.

If you want, remove the strut and take it to a professional and have them change the bearing, spring, strut, etc. For you.

And this is exactly what I did. Took out all 4 corners, and had an old work colleague do all 4 springs for 50 bucks... I'll gladly pay 50 bucks any day, not like i'm changing suspensions every 6 months.

Why not? If it's there, isn't it safer to use the wall mounted compressor?

Probably save time by not taking the whole assembly out and these can be used in tight areas.

I know techs are all about time because they're flat rate, but how much total time can you save on 4 shocks? Genuinely curious. I can't see it being more then half hour, max 1 hour. I could understand if you're doing shocks all day, then 0.5 or 1.0 adds up quickly, but in my time at the dealer over a few years, I can't recall shocks being replaced once... if I were a tech, i'd be using the proper wall mount compressor, I just don't see the risk vs reward to make a little bit of extra cash, but of course to each his own

Bilsteins, Tokicos are a couple of good brands but it depends on application. Monroe's are crap. Not worth the time to install them.

If you're working on an older vehicle that's seen a few Ontario winters it could be quite substantial considering time to deal with seized/rusted fasteners.

And that's why my vehicle has not been at the dealership since it left the lot at purchase. Not all failed shocks leak(valves could fail internally) and with our roads and potholes they're usually pretty much done in 3-4 yrs or less depending on driving habits. Most folks won't know what to feel for so they keep driving with worn out shocks and never think to have them checked out.

Yup it is so scary. It seems better to replace the entire assembly with the common Monroe Complete Assembly. While they aren't as of high quality, you get a bunch of brand new rubber pieces and bushing, etc so it kinda balances out. I myself am too scared to compress it myself even though the tools are free to rent.

Good price nonetheless.
