the pics show it. the shackle out at 35 deg is the passenger and it almost never moves. the one folded up against the frame is the driver and it bangs around constantly. audibly bottoming out on the frame then sometimes flexing back down to about 25 deg. as the other side does not move it screws up not only ride height but steering as the passenger side is now toed out severly and pulling. both shackles are tight to the point of being folded inward. loosening the pass side does not much for it moving up or down. any suggestions.
thanks

springs that are supposed to be different the same, or a spring made for one side on the opposite.
 
why don't you give us as much detail as you can, that way we're not speculating b/c we don't even know what your setup is...

also possible Hardcore Corner...
 
Move the rear shackle hangers back (towards rear of truck).

This is so obvious. Am I the only one that sees this?

hey

i bought the rig this way couple months ago. professionally built apparantly. dgangle it came as a kit and the other side works fine in it's location not saying that is the right spot or not just that it works and the other does not and they appear the same. dunno if the springs are the same they measure out with a 3/8-1/2" difference in length but i cannot force the passenger up to get 25 deg to take up the difference. BCC in vancouver said 25 deg is where they should be?? the same shackles are on the back but they are practically vertical. if u turn sharp to the right the shackle will hit the frame but if u turn sharp to the left it will not usually uncompress. same as a large speed bump it will compress over it and sometimes not always decompress after it. Large dips especially at speed are spooky as it hammers into the frame putting out the alignment and diving u for the passenger lane / ditch. both bushings are cracked the same, same tightness etc.
Maybe some pics from other setups.....

thanks
 
Something's off. If they were symmetrical at one time, perhaps one of the springs has been bent (and opened up) which would allow the spring eye to eye to stretch. How are the bushings? The length between the hangers could be off too.

This is the solution. Your shackle angle is way too horizontal.

totally agree

most sas's are done with a slug threw the frame who ever did the sas on this messed up. your truck must ride like hell, once you fix this it should ride alot better

you might want to go to trail gear or marlin and order a slug kit ad get it done right.
do you have any photos of the front hanger?

nat has the idea.

start over.
check the springs, the middle pin, the front welds, the frame, put the mounts in the correct spot.
that is so jacked up that I bet something else is also bent or damaged.

the way the spring mounts are in the rear is putting alot of twist on the frame when you turn. I would check for cracks along the top and bottom seams in the frame all around that area.

also make sure the springs are correct front to rear.
just about looks like you have one in back wards. not knowing what type or who made the springs it is hard to tell.

and DON'T EVER take any thing back to that shop. They have no idea of what they are doing and created a death trap right there.

thank goodness you have looked for help in the right place.

don't worry this can be fixed... just do it over and do it right.
lets see the front mounts as well.
 
front shackle pics

so the general consensus is this is kinda pooched eh. i have never seen another sas up close so did not know if it was done right or what. there are no cracks yet around the frame as it has only had a couple tanks of fuel thru it since this was done. i rreally appreciate all the help and input here as i do like the little red truck and she gets lottsa looks. lets hear what u all think of the front.
thanks

...looks like a drop front hanger. Nice. They must have done that because they didn't want to put the shackles through the frame. This -MAY- mean they know what caster is and didn't want to screw it up.. but I doubt that. More likely is they used the wrong springs and moved the mounts down to get the needed lift to keep the axle out of the frame.

btw that shackle resting on the frame is a quick ticket to a broken spring.

IMO you should get a front hanger, frame tubes, and jigs from one of the big vendors. Note that this will reduce your lift a few inches, which means you may need springs as well. I'd absolutely be calling that shop and letting them know how bad they screwed this job up.
 
IMHO Davez offroad has the best shackles for your toyota (View topic - SUSPENSION (leaf spring)). Buy that with a TG (or Datin: Frame Tubes and Jigs) kit to put the shackle tubes through the frame.

But you will need to measure the distance from the bottom of the frame to the spring eye. Stock height is about 1.75". If you run a 5.5" shackle, that distance should be 3.75". If you run a 6.5" shackle, it should be 4.75".

If you find that your distance from the bottom of the frame, to the middle of the spring bolt is greater than 5", you really need to replace the front spring hanger too.

Sorry for the bad news that the SAS on your truck is pretty much junk.
 
The passenger side isn't good either. And the drop hanger is way to low. Looks like they really went overkill on the front hanger, and it will not be easy to remove and replace with a better design.
 
thanks all

at least i know what to do now. hey GRM thanks for the link in there is the picture i wanted to see. i do not now who the shop was but i do know the guy i got the truck from and will let him know.at least the truck was cheap i should know better by NOW...........
 
While you're fixing the SAS, be sure to take off those ridiculous spacers on the front wheels, before the knuckles/spindles are ruined.
 
I have to agree with the others.
also need more of a side shot along the drivers side going across.

from the one drivers side picture it looks like your steering box arm and the cross over rod will hit your lower tie rod if the suspension is compressed. that breaks your steering box.

don't worry to much, this can also be fixed when you re do the mounts.
 
Agree

I agree with what has been said, mount it through the frame, get some new springs and front mounts and call it good. Here is some pictures of my 1991 4runner SAS, this is the perfect shackle angle, even though i wish i would of moved mine a inch more forward, it turned out great:), won't let me post the pic try i"ll try again later
