The manufacture of coil springs and leaf springs is not an exact science. Springs of technically identical material composition and identical manufacturing processes will often not respond identically. There are tolerances in their chemistry, tolerances in the size of raw material, heat treating and cooling tolerances, and manufacturing tolerances ... and those tolerances can stack up to where one spring responds considerably different than another that is supposedly the same.

 

I rearched my left rear spring 1 1/4" .. left side sat a little less than an inch low. now measures 45 3/4 both sides rear and 45 1/8" Left front and 45 right front, Full tank.

 

Not sure if its ENTIRELY related but a few weeks ago i watch some NTSB full front collisions and it was intersting to see how the Ram equivalent of the the F250 (2500?) folded so bad the bed collapsed into the cab due to the frame breaking /bending so badly. The chevy pushed into the cab but not as dramatically, the F250 frame with stood the crash test and the bed never even touched the back of the cab. Thess were all comparable model types and same year. So for that and a number of other reasons i stick with ford super duty. Could change at some point, but haven't yet been compelled by anything ive seen. My company uses Ram 2500 pickups for thier field techs and the transmissions seem to need constant servicing or replacement, and that is occurring with 30-60k miles... complete failure on many of them.

 

Has anyone else contacted Ford directly and started a case with them for a solution to the Super Duty Lean? Background: we noticed the lean on my truck a few weeks ago and took it in to the dealership Monday to have them fix it. I pick my truck up today with no solution or fix for the lean. My husband and I bought this truck and had Super Springs installed specifically so we had the set up to carry the new truck camper (TC) we were purchasing. The truck handles the TC perfectly, except for the lean, which is unacceptable. I have read the information on here about the use of shims, replacing faulty springs, new leaf springs, spring spacers, leveling brackets, leaf spacers, and U-bolts to correct the lean. That's all well and good but I have to find a way to convince Ford and the dealership that this is a warranty issue AND it has to be fixed. And another thing, how is it a biology professor such as myself has the where with all to search for a fix but a Ford technician can't figure out how to fix it? SMDH.

After reading the threads on here I decided to call Ford directly and they "escalated my case" by giving me a case number and telling me they were sending a letter on my vehicles situation to the service manager at my dealership and would coordinate with the dealership to come up with a fix for my problem. I'm trying to find anyone else who might have contacted Ford and has a case number for the same problem. Any help would be appreciated.

 

Ford can only cover a lean, when the trucks unloaded. If it's with in 1", it's normal like many trucks. If it's way off, check the body mounts, and front spring length with the truck on a lift. Unless i's off by a foot or something crazy when loaded.

My work truck has a massive lean left, because I have a 400# load bank resting on the left side of the utility body today.

My personal truck looks level, but I won't dare get the measuring tape out. I don't want to know if it's leaning. LOL.

If the truck leans with the camper on, get some airbags to level it. Our camper was way heavier on the left side. Some are heavier on the right side. Due to their oddly shaped nature, I don't recall a camper ever being equal side to side.

Sometimes, swapping left and right springs works out.

 

you need to provide more details. has it leaned since day one ? only since the super springs were installed ? only when the camper is on the truck ? im no professor but figuring out why a trucks leans can be just a matter of good old fashion common sense and process of elimination.

once you find the root cause of the lean, take a look in the service manual for tolerances in ride height tolerances from side to side. while these tolerances wont really apply to after market spring packs, it will still give you a idea what the allowable side lean can be. my guess is the lean has to be over 3/4"-1" before the manufacturer considers it a problem

 

 

Remove camper. Jack up rear of truck by diff and remove rear tires.

Is the front level? Measure fender ht and bumper ht. If it's perfect, then the problem is the rear springs.

 

How do you guys like the ouo levelers?
