I have had a few f250 and 350s over the years although nothing as new as what you have. Some of the things I have encountered: When changing brakes just assume you will have to buy caliper mounts. I have never had so many caliper mounts go bad on vehicles I have changed brakes on. They constantly sieze up and you will wear one side down bad. While the other pad looks fine. This could be relevant because right after I got my 2005 the outside of the rotor looked good but the inside pad had wore down to the metal backing pad. If I backed up the metal pad would slide out of the caliper mounts and would get lodged locking that wheel up. I have greased these slide pins up more than anything else and it doesn't seem to matter after a few years. My current 2005 had terrible ball joints on one side but it just pulled one way. It didn't feel locked you just had to counter steer or it would pull to one side. I had an older f250 and the front u joints went out on it. This was bad because if the ball joint was just right the steering would be fine but if you rotated the ball joint say 90degrees it would lock up the steering. The ujoints had 2 bearings locked and the other 2 had the rollers missing so in one direction everything was freeish and the other you couldnt turn the wheel. Or what was really fun was if the axle started spinning while driving it would violently crank the wheel left and right. I thought something was broke. Thanks a lot for the insight. Fingers crossed. Hasn't happened again. Still I appreciate the advice. More to consider when it does happen again

Put it back in 4WD and drive it and see if that changes anything... or if it keep doing what your saying happens Did exactly that today as it was moderately pulling to the right. Created the same results. Wobbly front right tire and pulling to the right hard. So the 4wd engagement is the trigger. It is at the dealer now. Thanks!

I once had a similar experience with an International Scout that had a Detroit Locker in the rear differential as a factory option. One of my back tires went flat on the highway on my first western trip, and I put the spare on. The spare was about an inch less diameter than the tire that had gone flat, and when I got up to speed after changing tires,the steering suddenly felt like it had somehow "locked up" in a hard right direction! Took about all I could do to wrestle it back into my lane and keep it there until I could get of the road. I crawled under and looked over the steering, tie rods, springs, whatever else I could think of that might cause a sudden extreme right pull, and found nothing visible. When I fired it back up and started forward again, the Scout steered normally on the gravel berm and as it got back up to speed, and just when I thought it was some sort of fluke, it did it again. The second time, just as I got off onto the berm, I could feel it "unlock" and the steering return to normal. That was the clue that told me it wasn't a steering system problem at all, but was the locker in the rear that just couldn't handle the different sized tires. The locker would come around to the next spot where it could engage and lock both sides of the rear axle together, and that old short-wheelbase Scout would almost swap ends and head back home, and since it didn't have power steering, it was a real handful until it got onto a lower traction surface and unlocked itself. I noticed your year of F350 4X4's has the Electronic Differential Locker. Sounds like that could be doing something similar in locking and releasing randomly, maybe as a result of a faulty control switch or sensor? I googled "2013 F350 4X4 problems" and found a few other guys had some trouble getting them to unlock with the EDL. Seems like most owners like the system, but it does a slight tendency to have some control quirks. Russ, I believe you are right. Please note the previous post. Thank you

A quick Google search says it's most likely a bad u joint. You are right. Evidently there is a u joint associated with the axle that engages 4wd and mine is not releasing. Just got the call from the dealership. Thanks for the insight
