I have a 2008 E-350. It now has 450 miles on it. I have had wandering/steering correction while driving since new. HELL, it is still new! IT IS ANNOYING AS HELL!!. I think it actually takes some out of you by the end of the day. I drive in Maryland and the roads are pretty good, except for the city. It is used as a service van (tool boxes, parts, etc.). I have had Ford E-350s in the past with the same issues new from the factory. I had a few Chevy Express 350 and they drove way more smoother and No steering wander. But I have no choice in the matter when it comes to purchasing. I have tried adjusting the tire pressures up and down. 80psi front and 80psi rear has given it the best so far. I am thinking of attempting of making this gearbox adjustment to see if I get any more stability. Any other suggestions I might try before doing this?
All the feedback I have gotten is that new factory boxes are hit and miss if you get a tight one or not, and I think that is evidenced by the fact that mine was awful at 16k miles (as were many others around the forum).
I have a 2005 EB 6.0 4X4 with 315/75/16 tires on factory rims.
I off-road pretty seriously very often. I have a four-inch lift.
I tow (not heavy) a lot, down to loreto with my boat, etc. often.
My box is tight despite the "abuse" after 70K miles.
Big off-road tires like mine (BFG KO AT) plus a lift make slop/wander
I think I just happened to get a good box.
I also installed LandYot radius rods, after already having a rear sway
bar and bilstein shocks.
The radius rods made an enormous difference
in steering response, so much so that the first time I got on the freeway
by my house I turned in too much and had to saw the wheel back
the other way to avoid hitting the inside curb.
My truck seemed to "dart" into the corner, and after the mushy feel
of driving with the back axle not solidly controlled by radius rods, I
had to re-learn my newly responsive steering pattern.
Just another data point for you all...

So what do you have to do. I was out looking at mine, and it lookes like the nut is under the allan screw?? You have to loosen the nut, then make the adjustment with the allan, then tighten the nut, test drive and make more adjustments?? Just want to be sure before I start messing with the steering box!
