I have 2 F-350 4x4's and they both wander back and forth when driving. They feel like they don't have enough caster.
One is a 2000 V-10 extended cab with 8 foot bed. The other is a 2015 6.7 diesel crew cab with 8 foot bed.
I have driven the 2000 for so many years that I have grown use to the very slight sawing of the wheel to keep the rig straight. When my wife got her 2015 it does the same thing. The 2000 is leaf spring and the 2015 is coil spring. This bothered me when I first got the 2000 (used) but I just figured it was part of the charm of a big truck.
I know I could put a caster shim in the 2000 but there must be a better way to solve the problem.
Both are stock, no lift and no heavy winch or stuff.
Any ideas would be great.
thanks

 

I would assume the 2015 has a warranty and would take it in and have it looked at, the 2000 just might need a redhead steering box to replace the old steering box.

The 2015 is in warranty, only has 5000 miles on it and its bone stock.
I don't know if this is the way the F-350's are of if I have two goofy ones.
I live quite a way from a Ford dealer and would rather fix it myself if possible.
Thanks

 

What is the toe set to?

 

My 14 cclb is the same way. I had it aligned at a friends shop at 3000 miles as it was cupping the tires already. The toe was out and the caster was barely out of spec. I lifted it shortly after and everything remained the same. You can try a set of caster bushings to push the top of the spindle back but it needs aligned to know where you are at. If you are cupping tires you could probably try a set of 2 degree bushings and see if if helps. I'm going to guess if the dealer aligns it and it's in spec they won't make any changes reguardless of drivability.

 

I never thought of toe, I will get an alignment and will also look into some caster bushings.
This may just be the hot ticket.
Thanks for the thought

 

Looking forward to a reply from Red-Head for a custom box idea.
Thanks
