Purchased a new 2012 F350 and it drives great in the city and highway but when the highway starts to bank, the truck likes to drift downward into the low side of the bank and it takes at least 20 degrees of the steering to the other direction to hold the lane.
I didn't have this problem with my 2006 F350. Is anyone else out there having this problem or have a solution?
Similar problem with my f550, if the road crown is just right it seems to have a mind of its own when it comes to where it wants to go.
First time it happened I though I had a tire go out, plus I probably would have been in the ditch if it wasn't for the fact that I'm use to driving a '99 that had shot ball joints and a loose steering box....

Try adjusting your air pressure, I notice mine pulls a lot more when running 75psi tires when empty. If I air down to just above the TPMS when empty the problem goes away.
Since I tow so often. I typically put up with it, since I don't want to air up/down almost daily.

how far down can you go without the tpms light go on, I know what the door says, tried 65 once and light came on am running 75 like you said, which is better, usually run 80 when I have have the camper in the bed. But you are right better a 75 than 80, had the same issue with my 04 F-350
That is a great idea. I will try it tonight since I have 2.5 hours of highway driving to go home. Also, I was thinking about different tires and a tighter ratio steering box might help the issue. What is your opinion on better tires and a tighter ratio steering box? I want BF Goodrich KO's.
I checked the tire pressure last night and had 60 PSI in the front and 80 PSI in the rear. I set alll 4 to 70 PSI. Changing the tire pressure improved the handling. Thank you for the information. It is amazing how changing the tire pressure can change the handling.
I run mine at 65psi when I'm unloaded. My understanding is the TPMS is set for 62 psi by default. Of course your tpms or your pressure guage may have some differneces in their readings. If you trigger the TPMS, Just air back up to 80 psi, go around the block and try the next higher pressure.

Add sone Castor shims...that will also help as the '05 up trucks have 1/2 the castor they need.
