    Has anyone experienced this with their truck? It's an 86 with 4" Rancho 86206 springs in front, 4" blocks in rear, dual ProComp ES9000's front and rear, ORD H.D. front shackles, ORD swaybar disconnects. Noticed it listed on the left a bit when i went to the garage. Got the measuring tape out and started with the axle tubes to the ground and all 4 points were fine (tire pressure is all even). To the bottom and top of spring packs at the axle, fine. Now at the front and rear points of the front springs there's a 1/4" height difference, lower on the driver side. The rear is also about 1/4" lower on the left (original springs). The lift was installed the summer of 1999. Most of the driving is done with myself as the only occupant and I commute alot. Is it possible that the left spring settled faster due to the weight being on the left all the time or that the left will settle more. Any insight would be appreciated.
    Sorry for the long post.
    Thanks.

    Mine did the same thing. It's not uncommon for the springs to settle or sag at different rates. I corrected mine by taking off the spring packs and swapping a couple of the leafs from one side to the other. Depending on how many leafs you move, the ride height can be evened up. jt

    The driver's weight can cause this. I've got an uncle that used to weigh over 300 lbs. He had a stock Scout that he drove every day. After about 5 years that thing sat at least 1.5 inches lower on the drivers side! [​IMG]

    "Frankentruck" has the same problem...but its the drivers side rear thats low, maybe 1" or so, or else all three other corners are too high. I swapped springs from side to side, no change. I measured as you did axle tube to ground, same height all around. I'm betting my frame is tweaked, since i bought it seperately from someone.

    Amazing, but on flat ground, that 1" height difference is EASILY seen, and really pisses me off. You might call some frame shops as well, some will look at it for free. Local spring shop also told me they would even it out for $275. Personally, I could care less if the rear of the frame is bent, as long as the body/bumpers/axles line up, which they do.

    Maybe If you just add a couple of sandbags to the side that sits high. Check first with the weight of a person how much you need, It shouldnt take much to even it out. And if you drive around that way for a while it will finaly fix itself..

    I was getting a decent amount of rear sag until I took off my custom bumper, spare and swingout tire carrier... I had the spare off to the drivers side and that side was sagging pretty good...

    Do you have anything up front that weighs alot? Extra battery, etc?

    Jeff - I was thinking of switching the springs for drivers to passenger side and have it even out that way over time. Probably have to switch it every year or two. Good way of checking the undercarriage thoroughly. Is that a Superduty that you own? How do you like it?

    Harry - That makes sense that the drivers side would sag if the weight is on the left all the time. 1.5" must of been noticable, 1/4" was just detectable.

    Dorian - Sounds like yours may be the frame. But would the tweak maybe affect the opposite corner also?

    Espen - What I might do also is any tools/misc. stuff in the truck could go on the passengers side and switch the springs ( when I get the 4" ORD shackle reverse kit).

    Michael - Congrats on the truck of the month. That's an awesome rig. When I build my rear bumper/tire carrier, I'm going to centre the tire so that it's even. The only think that weighs alot on the drivers side is ME, 260 lbs.

    Thanks for the suggestions guys.

    Thanks!!!!

    Ya, I was going to build my tire carrier that way, but I got the swing out tire carrier part for free that my friend made. He smoothed all the welds and everything and it looks great... So I figured, why not, and bolted it up...

    It was VERY noticable! That Scout always looked like the drivers side was parked in a hole! [​IMG]
