Need help with steering problem

[jello]

Over the last week my truck has developed some steering issues.
First I went to turn left and when I straightened out the truck was pulling hard to the left.

Then when I turned right it wanted to keep pulling right. Sometimes I'll be going down the road very slow speed and it goes from left to right like I'm driving in ruts.

I did a search on a few forums and thought maybe it's the valve in the gearbox. So I've been driving it until it does it more consistently so I can figure out for sure what it is.

A couple of days ago I noticed that my brake pedal would kick back, and now the power steering pump is whining, but not all the time.

So do I have a bad pump? Bad steering box? Or bad Hydroboost?

How do I test these?

I seem to have the same issue, any luck finding the problem? I just replaced all of my power steering lines and am sure there is no air in the lines.

Check the (relatively) easy and (relatively) inexpensive things first:

- tie rod ends
- upper and lower ball joints
- drag link joints

Raise the vehicle on jack stands via the frame or suspension, so there is no load on the tires when you check these items. If any are loose, they can cause steering funnies.

If all are good, then suspect the hydraulic system. Check the fluid level in the reservoir. Then listen for steering pump noise while idling, and then listen for noise while turning the steering wheel from one full lock to the other. Do all this with the front tires off the ground. Last, check the pump and hoses for leaks. If any leaks, these need to be corrected with new lines or new pump or new gearbox seals. If any noises, fill reservoir to proper level and retest. If still noise, pump likely needs replacing.

In my experience, replacing a gearbox is very unusal. The input and sector shaft seals can be replaced in most cases.

I finally had enough and took mine (2006 F350 SD 6.0 4x4) to the dealer. "stealer"
Had the Hydro-boost replaced and the steering gear replaced. After all wheel alignment, it was over $2K My truck had just over 41K miles on it.
