4WD caster
I took my 2009 250 4WD Super Duty to the shop Monday for a front end alignment. I spoke with their front end man about what I had read regarding caster, that people were recommending 3-5 degrees as opposed to the factory specs. He told me that he couldn't do that with the 4WD without changing out a cam in the control arm. What do I need to get that done?

I searched the Moog site and the ones for a 250 can be quite expensive. The K80154 allows +/- 2.5 degrees adjustment and costs $114.40 each. The K8977 allows +/- 1.75 degrees and costs $22.30. I didn't see anything that allowed from 3 to 5 degrees adjustment. That first option seems to be quite expensive.

It is likely not listed under the F250. This is common. Tends to mean it's actually for another vehicle but WILL work on your truck. Might have to search the forum, I'm sure it's on here.
Auto parts stores used to hate me when I was younger and modified cars a lot. I would often walk in with a part number, and if I got the guy who knew me he'd just run the number, grab the part, I'd pay and be on my way. But when I'd get a new person, They would insist that they couldn't get me a part unless I told them what the vehicle was...so the manager would have to come over and get involved, and actually train the new person on how to get around their system. I don't know how many times I'd walk in and ask for a part, and get asked 'What vehicle is it for?' "Well, I'm putting it on XXX but you won't find it listed under that because it's actually for YYY." *blank stare* "Just get me the part."

Team TTB decided that running on the ragged edge of absolute minimum caster was a great idea. Some guys never have a problem, others fight DW for months or years before finding a solution.

I don't know if the death wobble is my problem but the truck shudders and rides rough at every speed. 40 mph, 60 mph, 70 mph, speed does not matter. Today I reduced the air pressure to 45 psi on all four tires and it did not help. When I am rolling along on a smooth surface the truck feels as if I'm running over bumps. I may seem as if the obvious problem would be the tires but it did this when I bought the truck and continued after I installed a new set of tires. About 3000 miles ago I replaced the passenger side universal joint in the front axle. Those symptoms went away with the new joint. The problems caused by the bad universal joint were not present while driving in a straight line so I'm convinced it is not another bad u joint. In the video above the death wobble is present after hitting a bump or in curves. The rough ride I'm experienced goes on all of the time. I suppose it could be driveline related.
