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?

 

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
more noticable.

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...

blowhole,

As a piece of information...if you look at the top title line of all threads there is a pull down labeled "Thread Tools". Pull it down and you can subscribe to posts you like under that menu item...

Not that your way doesn't work...it is just that you can do it without having to post...either way works so chose your poison.

End of off topic editorial.

I will definitely try this adjustment. I had an 04 HD 250 with this same problem. I just picked up my 05 Ex LTD and same this. Other than the wander this truck is awesome. Hope it works. thanks

 

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!
Thanks!!

 

Yes.

Here are the instructions for you:

Locate the allen head bolt and locknut on top of the steering box (close to the radiator). I believe the locknut is 5/8".

Mark the allen bolt so you can tell the orientation that you started from and then loosen the locknut.

Turn the allen bolt clockwise a quarter turn to tighten the gear mesh. Tighten the locknut back up and take her for a spin.

In reading posts by others who have done this, the allen bolt seems to get turned somewhere between 3/4'rs and 1 & 1/2 times before people are happy with the results.

Be careful, because if you over tighten the steering may be so tight as to get extremely stiff on a tight turn, causing you to veer off course.

Repeat the tighten and test drive until you're satisfied with the performance.

If you over tighten, turn back the allen bolt a quarter turn counter clockwise.

There is a risk of over tightening the box and causing it to wear out prematurely, so I tightened it to the point where the slop was gone, and no further.

Good luck!

Thanks Stewart. Just wanted to be sure before I went messing things up. I bet this will help with pulling my trailer!!

 

More than welcome!

had my steering box adjusted friday, took about a full turn of screw to get it just right, wow what a difference, makes for such a nice ride especially towing.

1/2 turn of the allen head screw tightened up the steering a little. Tommorrow another 1/2 and well see what happens.

 

Go slow on the adjustments...I made 1/4 turns at a time and took test drives in between.

There is a real danger of overtightening this and causing premature wear to the gears...so go slow is the best advice.

It sure makes a huge difference though to get that play out of there.

will this work on my 2wd ex??

 

Yes it will.

 

Here is a picture. Thanks for the great description. Adjusted mine 3/4 of a turn. Worked wonders on the steering.
