Power Steering Locking Up and Brakes Failing

Posted

Hey guys I’m having a pretty scary issue with the truck recently that got pretty bad yesterday after a long trip. 
 

This issue or one similar seems to have occurred to the previous owner only 13k miles ago. This is the invoice for his repairs at 198k (212k now) Invoice

I also have a synergy steering box brace. 
 

Whenever I’m not on the gas or the truck is decelerating the steering will get very heavy, if I’m on the highway I can tell there is no power assist when I’m on the gas. If I’m pulling into a driveway or pulling up to turn at a stop sign or something, the steering will usually lock up completely. Taking my foot off the brake and turning the wheel the other way and trying again usually frees it up then it acts normal until I slow down again. No groaning like it does when I’m not moving just silence and locked whee. I flushed out the nasty ATF  yesterday and replaced with straight Napa PS fluid. No real difference. The ATF was bad, smelled burnt and had a lot of deposits in it. Way more than it should have if everything was flushed and replaced. 
 

Where do I start?

    It sounds like something in the steer box is binding. If the fluid has been in there for a very long time, it will start wearing the metal parts as contaminants build up.   PS pump may be we

    How does temp affect it? Both ambient and first start versus up to temp.   I have a Borgeson steering box that is the larger than the original, and by their own claim, a newer design. It is

Ok guys bit of a bittersweet update. Long story short, the guy with the used pump and box tried to scam me. Unfortunate but I decided to just say screw it and ordered a redhead and a psc hi-flow pump for the truck. Praying it isn’t a hydroboost failure. Also getting the PS filters and looking into the cooler. Next week Saturday the truck goes on the lift for a whole lotta fun stuff and it needs to be dialed in by then. Will keep y’all updated if I get it fixed. 
 

Was thinking about opening up the HB and seeing if there’s any crap in there, any tips or advice for being sure that sucker is clean?
