Front struts; what internal spring compressor did you use?
Hey all so i got these front springs and struts sitting in my garage waiting to be installed for months now... i want to do it!! i got my rear suspension in and it feels good. Well i want to get the front refreshed before i get my subframe connectors welded up so.... lets do this
What type of spring compressor did you use? (link?)
What else did you replace at the time? Im going to replace front struts/springs and sway bar bushings.
Other special tools needed?
Things you wish you knew before starting the job?
Is this do able with hand tools and floor jack?
How scary is it to do this job? The thought of the spring un compressing in my face is nerve racking...
How did you 'index' the springs? How crucial is this?
Any information/advice is greatly appreciated!! Thanks all
EDIT: ops if a mod sees this the thread name was supposed to be front springs... not front struts.... lol

Re: Front struts; what internal spring compressor did you use?
This is what I used
http://m.ebay.com/itm/400993435820?_mwBanner=1
I did it on a lift however if you jack it up enough to have space where to insert the compressor I guess it will work. Just make sure you skip two coils per side or else you wouldn't be able to take it out.
Also cut a piece of pipe 1" long and slide it on the thread. This allows the compressor nut to stick out further.
Indexing is easy. There is a hole in the bottom of the A Arm where the end of the spring needs to be visible.
Just do a search on TGO as there is a lot of information and links to YouTube videos

Re: Front struts; what internal spring compressor did you use?
I used a loaner tool from Autozone for free. It was the OEM brand. You will also need a 5" spacer tube cut out of 3/4" water or gas pipe.

It worked fine but man it gets tight. You do not want to mess around with half-*** compressors.
I only needed to compress mine to get the control arm out of the way to do the motor mounts.

inspect your strut mounts carefully and replace if needed.
an alignment is recommended after replacing springs as it will change ride height. you may want to consider replacing centerlink and all tie rod ends while you're there if their age and condition is unknown. may save another alignment down the road.

Re: Front struts; what internal spring compressor did you use?
We have just done ours with a floor jack as far out on the a-arm as possible.
Its good to take a piece of chain and a bolt to chain the spring to the arm though to prevent it from flying out if something was to happen.

Re: Front struts; what internal spring compressor did you use?
i did not use a spring compressor either good safety step with the chain just incase the jack slips or clasped all at once 😲

Can you guys also explain a little more what the 3/4-1" 'spacer tube' is used for?

So i was actually thinking about dropping the a-arm and getting a shop to press in some new ball joints and bolt bushings. Are the bushings that hard to do by hand? same thing with balljoint? i was reading some people had trouble trying the moog as its 'oversized'.

Re: Front struts; what internal spring compressor did you use?
Yep. Put the jack as far out on the a arm as possible. A good ratchet strap works good too to hold the spring to the A-arm.
Works like a charm on lowered cars. Stock height and/or heavy springs can be more difficult.

Re: Front struts; what internal spring compressor did you use?
A jack under the a-arm is still helpful to move the arm up and hold it in place while you get the strut bolts back in. You would just be having the force of the spring being held by the compressor not the jack.
Its not a scary job, but it has the potential to be dangerous. That spring has a LOT of stored energy when compressed. Get in the wrong spot and let something slip and that sucker will fly out.

Re: Front struts; what internal spring compressor did you use?
Replace the strut mounts. The rubber and the top bearing only lasts as long as the struts do and should be replaced at the same time as the shocks. They are a wear item

Re: Front struts; what internal spring compressor did you use?
I suggest Founders mounts if you want aftermarket. I run Delco OE though.

Re: Front struts; what internal spring compressor did you use?
I just did this 6 weeks ago since I went from old stock a-arms to awesome tube UMI arms. I used an internal spring compressor that i rented from Advanced Auto Parts. I ALSO used a floor jack. you have to figure out the "sweet spot" of where to line up the 4 arms (hint, there is a stickie/thread containing photos of this). I compressed the spring with the compressor out of the car in a diffeent room so in case it blasted loose it didn't hit the car. once the spring was compressed I delicately positioned it into the upper pocket and used a floor jack to bring the a-arm up to mate the two together, MAKING SURE to index the spring properly. It was a balancing act to do, but it worked. those springs can be dangerous. for removing them I used the safety-chain method as well.
