I'm stumped! My truck is slightly leaning!
 
My truck is slightly sloping or leaning on the left side.
The left side rear wheel well is 1inch and 5/6 shorter than the right wheel well.
and the front end is about and 1inch and a 1/4 difference

What puzzles me is that my left torsion bar is raised higher than the right side torsion bar by about 1/2 inch yet the ride side of the truck still sits higher!

What the heck is the problem??

The tire pressures are very close to the same psi
So I cannot tell and difference from the tires and the leafsprings look fine so do the shocks so whats goin on under my truck???

Ahh...the beauty of the elusive gas tank :lol:

It's normal...no reason to fret dude :thumbsup:

Ahh! damg didnt think of that But!!
It never leaned until I got my body lift and tires but just lookin at the right side it deffently does look like it sits higher

And I dont think my gas tank can cause my torsion bars to be set different and still have the right side sit higher!!

Wandell I need some input

not as much a problem as you think
 
I have a 99 Expedition, and now a 97 F150. I have played with both trucks torsion bars. And I can tell you that the keys do not set on the torsion bar at the exact same amount of threads on the adjustment bolt.
Since I was lowering my truck, it is much easier to see. Once the lowering keys are installed, I lower the truck without bolts in the keys and measure the distance on both sides as you have. Once raised again and adj. bolts installed, one side adj. bolt makes contact befor the other. This makes sense, seeing how the truck sat unlevel. Count the difference between sides. Use that number as a rough constant. When you are at the height you desire, fine tune by measuring height as you origionally did, turning only half a turn each max to balance.
If I was trying to balance a stock keyed truck, I would do as follows.
1. Measure both sides while truck is on level ground.
2. -the higher, and + the lower adj. bolt one turn
3. remeasure
take it from there, but only do a balanced amount of turns to level.
A bad thing would be to try to crank one up or down several turns and letting that be it. Chances are you ride would feel like crap. The truck would torque to one side in a twisting motion ,when you hit bumps. Thats because one side bar would be softer that the other.

My issue is a rear bed not being totally lever. I think I'm going to unbolt it and shim it from the chasis.

I've never had a vehicle that's had a visible lean to one side because of gas tank location.

:confused:

It's not something you would normally notice- you usually have to look for it. I've seen this come up on a few forums over the years- it's quite funny because people track it and notice it's worse with a full tank :lol:

True, full tank =more lean
 
I took that into consideration looking at my bed. But, Looking at the bed end to end I can see it's straight at the cab, down slightly on one side (driver) at the tail. So since the frame is not bent to my knowledge. I can just shim the bed to compensate. It's just the same as when a fender or door is shimmed.
The truck had a hard life for the last 208kmi. before I got it. I'm resurecting it.
As for the front torsion bar question I replied to. The tank offset would not come into play, since with the front wheels off the ground you can check the torsion bar key discrepancy side to side. It's about a 1/4" differece in adj. bolt to correct.

I don't think a major corporation like ford is going to develop a truck that leans and is noticable when the gas tank is full.

The difference in the wheel well clearence and space is noticable when looking at one side to another.

And plus I doubt anything could be to worn out on my truck considering there is only 62,000 miles on her.

Also how could my left torsion bar be torqued up more than my right side key by about 1/2 an inch and still the right side sits higher??

Jack the truck up by the frame and see if the lean goes away. If so it's in your leaf springs or torsion bars. If the lean remains then it's somewhere in the body mounts or frame. Pretty typical for the driver side to lean on a truck because there's always a driver and people also load down the driver side in the bed without even thinking about it. I see this every week and usually you just need to replace the springs or have the one side rearched. Best way to tell if it's coming from the front or rear is to put the torsion bolts at the same position and then measure from the rim to the fender and see if it's more on the front or rear.

lowflyingbird Apr 6, 2008 06:21 PM

1/2" on the adj. bolt & still lower?
 
WOW!!
That is more than I'd expect. Like I mentioned, it's usually like 1/4" diff.

Quite possibly possibly springs, but with your mi. that doesnt sound right.
My 97 has 208kmi. on it. The rear leafs were toast, I installed a set of 04 Lightning rears+ 2" drop shackles. My front bars are orig with the lowering keys adjusted evenly.
I did notice that the origional rear leafs were pretty crappy, only 3 long leafs with alot of arch to them. The 04 Lightning ones had a nicer leaf pac. with more slightly thinner leafs. Much less arch to them, but they held the truck up almost to the same hight. My 97 definitly sits better now with out a doubt. I just want to fine tune the bed as I mentioned.
Not the same issue as you have.

check your body mount bushings... make sure the factory ones are still lookin good... the factory ones could be just plain wore out! my ranger's body lift sat on top of the factory rubber bushings and when they started getting bad it leaned!
