: Spring sag, not a simple answer
Yellow Scout 04-27-2002, 04:50 PM OK here are the stats. '79 Scout II 345 4" Skyjacker Softride springs.Body mounts are perfect from a body resto a year ago. The spacer block is used to level the truck origionaly. Only "extra" stuff on the left side is a Hi-Lift but tools on the right side more than offset the weight of the jack and the battery. The truck leans 1.5" lower on the left both front and rear measured at the wheel well tops and at the marker lights to get a different reference point and the differences match. Also the angle of the shackles show the left side springs being flatter.
Front and rear springs removed. Front spring free height the same between packs and rear springs are 3/8 difference with the left spring being lower.
An engineer friend of mine states that the "spring rate" never changes only the springs "seem" to loose strength because they yield and just sit lower but will still flex the same amount as a good spring under the same load.
So, with that said with the front springs the same height and metalurgicaly speaking still having the same strength why does the front sag so much? The same goes for the rear except only a 3/8" difference not 1 1/2".
Can anyone shine any light on this perdicament? I am puzzled big time.

Scouttoo 04-27-2002, 07:41 PM Yellow guy, Orange guy here, There's a spring spacer that IH uses for reasons unknown. Go o www.binderbulletin.com & ask for more info, this subjest has been covered before.

You wheel it to much, lift springs are made for looks, not wheeling. Go SOA:smokin: :D :smokin: :D

From one newbie to another "Welcome" :flipoff2: :D:
now do what I was told to do when I first posted here and go do a search :D: (j/k)

Waking up a very old post.
So did you ever figure out why the Scout leans to the drivers side?
ihochad 08-22-2006, 10:11 AM Wow talk about bringing back the dead? I can not answer for this paticular truck but EVERY skyjaker softride spring set I have seen sags whether it is wheeled or just for looks.

EDIT::::
even more so after they have been cycled hard...

corncrasher 08-22-2006, 11:27 AM My stock springs are like this. one side is flater than the other. I removed the springs and swaped them side to side and put them back. the measurements did not change at all drivers side still lower. It's just a scout thing. I have measured everything on the frame and scratched my head over this and looked at other scouts and it is just one of those things.

That would indicate to me that it could be something more serious than sagging springs. Body mount / spring hanger??? Lots of things could cause this. It really isn't just a scout thing.
I put Rancho 44044 on my Scout and it leans to the drivers side, like a mo fo
I did a search and figured what the hell and wake up the dead:flipoff2:
The front springs are new and have only been on the ramp once to check to shock length. I will post a pic later. But I flexed both sides.
Re work a new spring pack:confused: I took the pack down to flat, but that was it.

Edit: I let it sit a few days and it levels out. Drive it around the block and it leans. At first I thought maybe the locker in the rear was binding the springs or something? or the rear springs (JY) were bent. But the front can't be that far off. As for fab mounts and hange lengths, everything is with in 1/16 if not spot on.
ihochad 08-22-2006, 02:22 PM what i would do it check to make sure that it is for sure a sag. it could be that something in the suspension is hanging up and causing 1 side to sag or possibly lift. I know that most of your underside is new so it could be something is too tight and binding then releasing as it sits or pinching it down and again releasing as it sits???? just a guess. I can't think of anything else that would make it do that off the top of my head.
binderbound 08-22-2006, 02:26 PM Are you a fat ass? Maybe its you breaking down the springs. j/k. A buddy of mine has been having this same problem lately. Stock springs in an SOA. Engine torque twisting on the frame? I dont know, I have a 4 cyl.:flipoff2:
nooblet 08-22-2006, 03:20 PM My scout leans driver also, with a SOA on stock springs. When I did the SOA I found it had spacers between the springs and the u-bolt plates on the driver side front and rear. I see now why there were there. Mine is not street legal and prolly never will be, so it can lean on for all I care! :flipoff2:
budget76 08-22-2006, 09:23 PM i like chad's idea. Maybe the driver side shackle bolts are so tight they need the force from turning to shift, and they very slowly even out as it sits. other than that, damned if i know. all i know's my rear skycrappers sag like a mofo, and i'm going SOA in the rear soon. yeah i know you're all way past SOA:flipoff2:
Mechanos 08-22-2006, 09:34 PM ...rear skycrappers sag like a mofo...
My rear skyjackers lasted 3 days on the 'con.... junk.
corncrasher 08-22-2006, 10:17 PM A lot of 80 somethin dodge pickups saged on the drivers side to. I have seen numerous SOA scouts that do it and talked to quite a few people that have had the problem. I figured thats why international put the spacer block in there because they couldn't figure it out either.
Sand73 08-23-2006, 09:21 AM That would indicate to me that it could be something more serious than sagging springs. Body mount / spring hanger??? Lots of things could cause this. It really isn't just a scout thing.
my 73 with SOA on 2.5 ranchos sags to the passenger side not the driver.
RustoleumWhite 08-23-2006, 09:45 AM Even with new mounts, new springs and all that jazz, when i first did the 44044's mine didn't sit right. Like was said, it just appears to be a Scout thing.
I installed (1) spacer in the back, and it fixed everything within a 1/4" or so. It weird that juts a little spacer in the right place can fix some seriously lopsided shit.
Course now that it has been wheeled/beat/tweaked/different tire pressures, bent springs... it never sits right now unless I want it too :D
My advice, for what its worth, if its a "pretty" Scout, and you want it to look good (i.e. level) make sure everything is Kosher as best you can (not bend mounts, over tight shackles, whatever) then add and subtract spacers to get it to level out and look good. As things settle/sag you might need to do it again in a few years, but hey if your after the looks, you got to do the work :D:D
Rock Tractor 08-23-2006, 10:39 AM When it's parked in your drive way, just have the tires on one side aired up more then the other and the rig will sit level:flipoff2:

Ok, that one hurt:( :flipoff2:
Yes Fawkin today! I am driving my chit over to IHOnlyNorth for some engine work and maybe a few other needed items if Jeff has time. This mo fo is getting on the trail. I might be walking home, but this bitch is going to the CON in Sept!
Nice tip on the shackle bolts tighter on one side than the other:D
Snoopy 08-23-2006, 11:21 AM Go with coil-overs, you can adjust them so they don't sit heavy on one side.
A buddy of mine has been fighting this 'sag' for years. He finally took it to a frame shop to see if the frame was bent. After they got it on the rack, they said it was, and they straightened the frame. This cleared the lean up. The buddy asked how the frame got bent and the answer was it was probably bent from the factory.
They said that the way the frame is welded together, it could have had some heat distortion which would cause it to twist one way. I'm sure we've all got some experience with metal warpage after some welding.
Now, that got me thinking but I'll say that I believe that most sag is due to the front perches not being at the same level. Meaning that when we do an SOA one sits on the housing, and one sits on the tube. That creates a 1/2" gap and when you consider that gap is at the frame rails, you could have a much bigger gap at the fender lips.
Just my .02

I will measure everything again. I went with a Stock Chevy SOA axle to avoid all that pumpkin grinding:grinpimp: As for bent frame I can just add a leaf to the pack to make it level too.
My dad has been watching my build up and about a month back he commented that I could tip over and still have my wheels on the ground. :eek:

What time are you heading over to Jeffs, I was thinking I would swing by and pick my frame up today so I may see you there.
