I have 2006 F350 single wheel, I got it with a level kit. I upgraded to a 8" Pro comp stage 1 kit. an since I have had it install my pitman arm bolt always comes loose I have used green, blue, red Loctite an still comes loose within 1500-2000 miles.

I noticed my dads 03 and my brothers 01 powerstrokes have a lock washer on there steering arm an I don't.

anyone have this problem?

Mine has a lock nut and Blue loctite Time to go see the dealer as i think it would be hard to find a lock washer that large at one of the Box stores

How tight you getting it? Sounds like you have never tightened it enough to fully seat the arm so your not getting the right clamping force from the nut. You need to order the correct socket (46mm I think) and get a 3-4' breaker bar on there and get'r tight!

There's a good chance that the splines in either the pitman arm or the steering box sector shaft are damaged now. Most like the pitman arm has damaged splines. That allows it to wiggle a little on the shaft that quickly allows the nut to get loose. I would try an new pitman arm and torque it down to spec and then again after a few hundreds miles.

That nut needs to torqued to 400 ft lbs or more if i remember correctly. I had to take mine to a shop. Hard to get that tight with all the crap in the way. I also put a tack with my mig welder on it so it wouldn't come loose.
