My FJ - Moog 'Tall' Spring lift / a comedy of errors

*** Update ***

So all said and done, I spent $40 on springs (got the rear FJ's free) and spent $340 on shocks - so $380 total for ~3 inch lift. It also has been a dramatic improvement over whatever was down there which I would assume was stock springs/shocks.

*** update complete ***

So after much reading and researching on here, I decided to try and replace my shocks and springs on my 3rd gen.

A buddy of mine has an '07 FJ 4x4 and he had rear springs lying in his garage, so I already had the rear springs taken care of for free which was awesome.
I found a pair of 4Runner 'tall' springs on here for $40, all I needed were the 5100's.

So I ordered the fronts here for $100 apiece (#24261425) and I ordered the rears here for $69 apiece (#24-100144)

The rig in question is a 1997 2WD 3RZ, 5 Speed.



Love the truck but with 200k on it, the suspension and brakes were toast. I already did the rotors and pads but the bouncey-ness of the suspension was terrible.

The top of the rear wheel well was sitting right around 34"


I did all my homework and got started early on Saturday



The FJ springs are a perfect replacement: slightly higher and a little beefier



The springs went in super easy with the anti-sway disconnected.

The springs brought the backend up to 37", giving me a solid 3" lift with the stock shocks.



I went to install the rear shocks and noticed that the eyelet on the bottom was wayyyyy too small. There was just no way they were going on without modification.
Gunna have to return the rear Bilsteins.

As any of you that have kids totally understand, you have very little free time for yourself. I really wanted to get this knocked out as this is my wife's daily drivers - wanted it to be done and done well - done safe.

So I was starting to really get frustrated.

At the exact moment the mail guy delivered my front springs!

:girl:

anyways, here is what it looked like with the FJ rear springs and stock shocks.





Here's the Moog 'tall' spring comparison with the stockers





Here's where I get pissed off at myself. I thought that I understood the process behind getting the new springs back into the front end. I wasted about three hours scratching my head about how to get the spring compressors to fit up inside the bloody fender.
I finally sat down in frustration and realized that you need to compress the spring and get it under tension, get the top threaded on, THEN get it back in the truck.
Now the problem I'm having is that my spring compressors are too 'fat' and when the spring is under compression, I can't wiggle the spring compressors out!

:dammit:



My frustration is boiling over by this point!

SO, I did however get the stock fronts to fit with the Bilsteins....



SO, Now I have 4x4 FJ springs in the back with stock shocks and in the front I have stock springs with the Bilstien shocks.

The Bilsteins alone gave me a ton of lift though - here is before and after





You can see the difference in height when I finished one side



So all said and done, here is the result




...and before....



All in all, the ride is a 200% improvement. No more bouncy bouncy in the back - its nice a supple now.

Same with the front. Im very happy with the ride.

It it a higher than I wanted to go as my wife is only 5 feet tall, but I'm sure it will settle.


I still need to get the rear Bilsteins installed and the front Moog springs.

I enjoy learning, but this one was just a PITA

:D

...and I'm only half way done....

*** Edit & and more update ***

for those that are looking for info and don't want to sift the thread, I ended up putting the spring perches on upside down which; a) is dangerous as I found out b) gives you about 2-3 inches too much lift!

so if your shock and spring look like this,

you need to take it apart and invert the perch so that the cone part of the perch goes up into the spring

like this

Long story longer, last night I took the fronts off and inverted the perch so that it was correct.

* copy and paste from last page below *


it was sitting at 37.5" with the perches in incorrectly and now it's sitting at 36 - 36.5" - also im sure it will settle a bit.

Which, honestly is perfect as it was just too high at ~37". Wife was complainin' and the camber was slightly off.

It's good now.

All in all the 2007 FJ springs in the back and Moog 'tall' springs was just right. Sits nice and level and yielded about three inches of lift. ride is SSOOOOOO much better.

Not sure if you tried this already or not but when I was installing my front eibach springs I couldn't get the compressors off either but was able to wiggle them loose after disassembling the compressor while it was still on the springs.
 
The spring perch on the front Bilsteins are upside-down. Don't ask me how I know that, it's definitely not from personal experience.

You should not be able to see the retention clip when properly installed.

I was told by Wheelers Offroad that this is dangerous, and the retention clip can come out.

ohhhhhhh crap - see what you're saying. The cone part of the perch is supposed to go inside the spring....

I'm confident that I did it consistently wrong, too. That would explain why the front end is so high with the stock springs. Putting it back to how its supposed to be will bring it down a bit.

I tired that - didn't work - However if I turn the spring perches around and try this again, it may actually work as the spring wont be nearly that compressed.

Going to have another suspension day in a few weekends.

That's what I had to do, when I used the same springs and compressors a couple weeks ago.

Roger that.

Unfortunately, I cant mess with it this weekend as my kid and I are going camping. I'm just going to have to go easy on it while driving around.

Next weekend I'll tear into it again.

I'm glad you guys are around - I have much to learn...



maybe someone else can learn from my mistakes

Yea, the rear 5100 bushing is too small. I pressed the one it came with out, and you can either buy the correct sized ones, or I just reused my stock shock bushings since they were in decent shape still. Food for thought. And yea, your spring seat is upside down like dude above said.
 
I spotted the headlights of a triumph street triple in your garage! I have an 08 street triple. It's a fantastic bike.

There ya go!

Yeah, it's the most exciting street bike I have ever owned. Not the fastest, not the most powerful or flashy - but for pure fun, excitement and SOUND, it's REALLY hard to beat.

Noted and noted!

thank you.

I'm guessing you used a vice to get the bushings out or something similar?
 
DO NOT DRIVE THE TRUCK WITH THOSE FRONT SPRING PERCHES LIKE THAT!!!

This is seriously important. The c-clip is not retained in that position and you can loose the springs right down off the shock.

Take that truck off the road and fix it right now. Do not pass go, do not collect $200. This is your wife's safety at stake (and possibly kids!?!).

The right way to do this: Buy the 5100's meant for your truck... (yes, they have 4Runner specific 5100's for your truck)

The rear shocks have the right sized bushings and are the right length for the stock bump stops (rear). The fronts will be valved right for a lighter 4Runner (of which you have the lightest!).

will do.

Won't be able to take care of it tonight, but it'll get parked for a few days.

As I recall I just clamped the shock eyelet in a table vice and used a socket and hammer to pound the bushings out, and then used the vice and lubed the bushing to push it back in. It was awhile ago though. If you pull out the bushing in the 5100 you can look up hourglass bushings, and find one that fits the OD of the axle peg and the ID of the shock, assuming there's issues getting the stock bushing to fit--like I said, it was awhile ago I did this so take my advice with a gain of salt, though if you research on here there's lots of write ups of removing/swapping the bushing out; assuming you don't want to return the shock and get different ones.

Since these aren't installed yet, I may just return these and get proper 4runner shocks.

I think the fronts, as they are already installed are not returnable....

:nono:

Ignore what I said, I just looked at my build and I had to turn the stock bushings down on a lathe to get them to fit into the eyelet of the 5100s (these were Tundra 5100s). I wouldn't worry about returning the front unless you don't like them; I really liked my Tundra 5100s when I had them and they weren't "meant" for a 4Runner either.
