I am no mechanical guy, but I am learning. So I am counting of the Forum to share their mechanical wisdom. Here is how my living posts work. Everyone is encouraged to post their comments, suggestions and improvements to my root post. I will update the root post with everyones improvements. Hopefully this will save readers from having to read and decipher hundreds of posts.

__________________________________________________________



TOOLS
Air Tools are VERY helpful
12mm socket and wrench
14mm socket and wrench
17mm socket and wrench
19mm socket and wrench
Torque wrench
Long stout flat head screwdriver
Spring Compressors (Air tools are a must if you choose this approach)
At last 2 floor jacks
2 Jack Stands
1 or more very strong buddies

Front (Approx 2 hours)

Step 1: Put Car on Jack Stands and Remove Front Wheels.
There is a good jack point at the base of the front skid plate

Step 2: Remove the nut and disconnect the swaybar link from the steering knuckle
HINT: Requires a 17 mm socket and wrench
Image

Image



Step 3: Remove front skid plate
HINT: Requires a 12 mm deep sock or extension
Image

Image





Step 4: Remove the front swaybar brackets.
HINT: The front of the bracket has a slotted hole. Remove the bolt on the back of the bracket on the RH and LH side, and then just loosen the front bolt on the bracket on RH and LH side. Now you can slide the brackets back and remove the stabilizer bar. If you take the front bolts out all the way, the stabilizer bar is unsupported when you take out the last bolt making the job more difficult.
HINT: Requires a 14 mm sock
Image

Image

Image




Step 5: Remove the lower bolt on the front shock absorber and coil spring assembly on LH and RH side of vehicle
HINT: Requires two 19 mm sockets or wrench. When you reinstall the torque specifications for strut bolt is 52 ft*lb
Image


Take note of the direction the strut bolts were installed. The picture below has the bolt in backwards
Image



Step 6: Remove the 3 nuts on the top of the front struts on LH and RH side of Vehicle
HINT: Requires 14mm socket or wrench for the front 2, the rear can only be reach by a wrench
Image

Image




Step 7: Remove the front strut assembly
HINT: To make this job easier you can remove the 2 spindle bolts where the spindle connects to the Lower A-arm. Requires a 19mm socket or wrench. The lower A-arm can now be moved out slightly to make room for removing the strut. This will allow the strut to be "un-screwed" through the steering arms. Line up the coil spring and gradually "un-screw" it down through the steering arms. Installing the new coil-over strut using the same technique. Be careful not to pull out too much on the lower A-arm or the half-shaft will pull out of the wheel assembly. When you reinstall the torque specifications for these bolts is 100 ft*lb
HINT: You can use a 18" crescent wrench and open it up to the thickness of the lower A arm and push down on the A arm while getting the bottom of the shock into position
Image

Step 8: Changing springs
HINT: You shouldn't stand over a spring compressor (see pic below). If it breaks pieces are going to fly and YOU'RE going to get hurt. Recommend throwing a moving blanket over the strut as you compress the springs. If the spring compressor breaks, the part will go into the blanket and not you.
HINT: Make sure the alignment of the strut bolt hole and the 3 bolts on top are the same old strut.
HINT: Air Tools and at least 4 good spring compressors are critical for this step.
HINT: You can choose to skip this step by taking the old Struts and the new struts and springs to a Tire Shop. The will normally setup the new OME Struts for $20 to $30.
Image



Step 9: Install the new shock absorber and coil spring assembly.
HINT: Initially mount the strut with one loose bolt at the top
HINT: You may need to use a large screwdriver to help pry the strut in place
HINT: Torque specifications for the strut mount nut is 52 ft*lb

Step 10: Re-install stabilizer bar

Step 11: Re-install skid plate

Step 12: Re-install wheels




REAR: (45Min-1 Hour)

Step 1: Put Car on Jack Stands, Remove Rear Wheels.

Step 2: Support the rear axle housing:

Step 3: Remove Shock Absorber bottom bolt on LH and RH side of vehicle
Image



Step 4: Remove the nut, cushion retainers, cushions, and shock absorber on LH and RH side of vehicle.
HINT: A strap wrench around the sheet metal dust cover of the shock worked great and immobilized it much easier than trying to hold the top of the shock stud.
Image

Image




Step 5: Remove rear stabilizer link by removing the nut and disconnecting the link from the stabilizer bar on LH and RH side of vehicle
Image

Image




Step 6: Start to lower the rear axle, be careful of the brake lines

Step 7: Remove the coil springs.
HINT: You may want to use a jack to apply upward pressure on the opposite side axle making it easier to install the coil spring.
Image



Step 8: Install the new coil springs.
HINT: You may want to use a jack to apply upward pressure on the opposite side axle making it easier to install the coil spring.
Image

Image


Step 9: Re-assemble the stabilizer link. Torque: 52 ft lb

Step 10: Install the new shock absorbers, the nut, cushion retainers, cushions, on LH and RH side of vehicle
Order of Rear shock assembly Torque: 72 ft lb[/B]
1. Nylock nut
2. Washer
3. Yellow poly bushing
4. Frame of truck (shock mount)
5. Centering washer (black)
6. Yellow poly bushing
7. Washer


Image



Hint: Use a Vice to insert bushing into the shock. Jump on two blocks of wood work if you have nothing else J
Image

Image




Step 11: Install rear wheels



CRITICAL: Get an alignment soon, allowing time for the springs to settle


Code:
2007 FJ Cruiser 4x4 Alignment Specs.	Min	Max
Front	Caster	Left	2.32	3.32
		Right	2.32	3.32
	Camber	Left	-0.35	0.65
		Right	-0.35	0.65
	Toe	Left	0.03	0.09
		Right	0.03	0.09

First off, great post.

You shouldn't stand over a spring compressor (see pic below). If it breaks pieces are going to fly and YOU'RE going to get hurt. I recommend throwing a moving blanket over the strut as you compress the springs. If the spring compressor breaks, the part will go into the blanket and not you. If you've never used a spring compressor before, spend $40 at the local tire and wheel shop to have the struts setup for you.


I disagree with getting an alignment within a week. You need to let the springs settle a little before getting the alignment done. I waited about 2k miles then had it done.

CRITICAL: Get an alignment with in the next week
All in all a great write-up that will help many folks.

There's a big gap not explaining how to "unscrew" the stock coilover shock assembly between the steering arms and also the other way to install the new assembly.

Otherwise looks pretty good. I also think you need to verify the torque values.
 
#8 ·
Nice detailed instructions.

Torque values should be given in foot-pounds not "PSI". Pounds per Square Inch is a pressure measurement not a torque measurement.

Everything you disconnect has a torque spec when you re-connect it. The FSM has a complete table (page SS-48, pdf attached).

Maybe a Modulator already changed it for me??? Here is now it currently reads.

Step 7: Remove the front strut assembly
HINT: To make this job easier you can remove the 2 bottom bolts from the lower A arm. Requires a 19mm socket or wrench. When you reinstall the torque specifications for these bolts is 100 ft*lb

Where the *bleep* was this post when I was trying to do my install?

Anyway - great write up! I'll use it when I swap my 886 springs for 885's. The 886s are too heavy for the FJ even with the Road Armor bumper and winch. I was not able to do a couple of trail obstacles without a little "human ballast" because the front springs wouldn't compress all the way.

Great post. I'll use it when I get to my lift. Thanks.

Doing my lift tonight, thanks for the write up. Question: How long does it take?

Cheers!

Disregard, I learned how to read.
Let me know if you find an errors in the documentation or any impovement suggestions.

oh man, I took 2 vacation days from work next week, i'm gonna go this alone!!! Haven't done any suspension installs ever. I have air tools though and jacks. The extent of my wrenching is adding the trd exhaust and cai, as well as doing oil changes.
 
#22 ·
Good luck.. I am sure you can do it. I would say what we are all here to help, but many of us will be on the summt slopes in the next comming weeks. Besure to post before and after pictures. Let me know if you find any flaws in the documentation or suggested improvements.

Thanks

Just a rookie observation from doing installs on an older vehicle.

Spray bolts with WD40 the night before. The years can make them hard to break.

While you're at it, spray the area for mosquitos. There's nothing like getting yourself into a really tight spot to get to a bolt and having to swat at eleventy billion mesquitos at the same time.

Last but not least (real rookie mistake) keep in mind that when you jack something up that allows the suspension to hang, if you need to crawl/lean up on your rig to get to anything, you're going to put that much more weight on the frame and whatever you're jacking is going to seem to rise. (I did that to an exhaust manifold where the bolts were just sitting in the holes. The bolts fly off at a high rate of speed)
 
#24 ·
Bit of a stupid question but where should I be jacking the vehicle, and also placing the jack stands for both the front install and the rear install respectively? The instructions with in this post reference additional jacking in certain areas to ease in certain portions of the install, for instance:
"Step 7: Remove the coil springs.
HINT: You may want to use a jack to apply upward pressure on the opposite side axle making it easier to install the coil spring."
Wouldn't jack stands be under the axle to begin with? I was under the impression that it was a jacking point.

Sometimes auto stores will have two different types, usually one more expensive. Get the one that you can secure safety restraints on, so if it does slip off it doesn't destroy your face. I'm glad I had the safer one, as I've had one slip on me before.

If you are really worried about doing this part, you can take it to a shop and they can have it done in 10 mins for you at a reasonable price. Usually fairly close to what it costs to rent a compressor for a day or two.

Great instructions.
x2!!

Question: Apparently my installer forgot to replace (and subsequently lost) the bushing and bushing retainer on the top of my right front strut. This obviously resulted in a clunking noise up front when hitting potholes, speedbumps, etc.

They're re-ordering those missing parts as we speak. However, where exactly on the strut are they talking about, so I can be sure the job was done correctly this next time?? And, is that a Toyota bushing that they forgot to replace, or a replacement one that came with my OME kit?

I am very happy to hear that this thread has been helpful. If anyone has improvement suggestions or tips to make the installation easier, post up.

Thanks

Saturday I installed new OME coils all-around on a friend's FJC; I've done the front now three times but that was my first go at the rear. One thing I noticed on the rear - the angle/access to hold the top stud on the rear shocks is very bad; it's difficult to get a wrench on it straight enough to not strip it, even after soaking the threads in PB Blaster. Solution: a strap wrench around the sheet metal dust cover of the shock worked great and immobilized it much easier than trying to hold the top of the shock stud.

bump...to keep it alive:)

the one thing on the post that was not clear to me was how to get the front coil/shock into the lower mount....what i found useful was to take a 18" crescent wrench and open it up to the thickness of the lower A arm and push down on the A arm while getting the bottom of the shock into position....hope this helps....RR
