!HELP! Steering Pulls Hard Left, Than Right...

[killacal]

I've been recently experiencing a very odd issue with my 2005 F250. Sometime when I turn (left or right) the truck starts pulling hard one way. When I correct it the truck starts jerking hard the other way. The most recent incident left me fighting the truck for almost 7 miles until I got it home.

I've not had a chance to jack the truck up yet, but when I did ball joints about 8 months ago everything seemed nice and tight.

Has anyone experienced a similar issue? This is the first time I've ever experienced this type of issue.

Update:

Just went out and took a look at the truck's front end. The passenger's side tie rod has seen it's better days, and the driver's side is borderline. I'll replace them both, and maybe a steering damper (seems like this is a common failure and mines original still). I will advise if this solves the problem.

It sounds like something is getting "over center" when you are turning the steering lock to lock. You will need an alignment after the tie rod ends are replaced, maybe something will turn up on the alignment rack.

Replace the front ujoints. That fixed mine. Those ujoints are the only greasable joints on the truck.

I assume you're talking about axle joints? I checked those when I did the ball joints and they were in good shape. I'll take another look this weekend when I have it back up in the air.
