I agree- I would not worry about the springs.
Here is what I would do first - measure the distance between the top of axle tube and the bottom Of the frame rail , and compare those measurements, left to right.
If the LR axle-to-frame measurement is the same as the RR measurement , then it
Is probably safe to assume that the springs and their mounts are OK. Same with the front.
Just left to right, not front to back. If the top of the axle to the top of the frame are also equal,
Or to the top of the shock tower,Say, then that is better yet- then your problem would seem to be from the frame up, or in The bed / body mounts.
Then go a little higher, axle tub to bottom of bed, or front axle tube to bottom of cab
Sheet metal, left to right.
Eventually, you'll come across the two inch anomaly . Then you can narrow down what
Is causing it.
If you do not get axle tubes that are parallel to an imaginary ( or actual- a stick clamped there) line across the Bottom ,or top, of your frame rails, then start looking at the frame , spring mounts, springs.
For instance, say that both of your right side axles are 2" closer to the frame rail than the
Axle tube are on the left side. If you swap the springs left to right, and you
Get the same results, the problem is above the springs, or both axles are big
A severely bent frame will often show up in uneven tire wear. Also,
The truck might "crab".It may seem like it drives straight from the driver's seat,
But to a friend driving behind you, you truck might look like it is going down the
Road skewed a little sideways.
I assume that you put new springs in all around to eliminate the lean. A possible scenario: If the truck was traveling along, and drifted off the road, for instance, and both right side tires took a huge Hit, on a square edged concrete culvert, it would be possible that the springs bottomed Out, and the top spring mounts were bent out of level. That would effectively lengthen The spring (since the mount is bent up), which would induce the same amount of droop Front to rear, 2" in this case.
This is all a big maybe, but that sort of event, where the travel is all used up, and a lot of
Force is transferred to the now-solid suspension, is when things can bend. I have no idea,
Of course, but that is something that could have happened in a previous life. I don't think
Twisting it up rock crawling would get the front and rear tweaked the same amount, but
The 404 guys on here would know about that.
