Power Steering Whine...

[snowman74]

Howdy to all,

Took a drive in the Bronco yesterday...haven't started her up for a week or so. While I had the windows down, I noticed the power steering whine was getting pretty loud, and was almost constant. It would whine more, of course, when I was turning the wheel...but it just seemed louder than normal. Fluid level looks fine to me. How do you know when one is going out? I'm gonna stick a Sag in it when it does...but don't want to tackle that problem today. Any ways to get a few more miles out of the one I've got?

Thanks!

They wine :lol: . Sounds like it is almost time to make the change. For a serpentine system it is pretty easy. All you need is to find a E250 and take the bracket and all including the high pressure hose. You may want to get a new hose. I fabricated my own including the bracket to hold it. It's harder to find V-belt stuff, but basically it is the same. I got a rebuild kit and for mine which was an easy job also. The only slightly difficult and impossible if you don't have access to a hydraulic press is replacing the shaft bushing if it is scored up, (the spiral grove is not a score mark, it is for lubing the shaft).

Good luck,

Two questions.... Where is the shaft bushing you are speaking of? I've never replaced a PSP, so I know next to nothing about how to do this one. I saw Boss's post on installing a Sag, and while it looks great, doesn't go into detail.

Second, what would score up this shaft bushing? My Bronco has seen lots of dirt, but no mud....and I haven't ever run larger than stock tires. I know running larger tires is rough on the PSP, hence people upgrading to the Sag...but I haven't really done anything that would have abused mine (I think).

Any links to a full "how to" on this....or just tell me where to look....would be greatly appreciated. Damn....I really didn't want to tear into this deal before winter, but it looks like I might have to.

I just found a good article on Hydro Boost braking systems if anybody is interested. Follow this link:

I may just wait on the PSP until I can do the hydro boost at the same time. Again, Boss has some great pics, but not much detail, so if anybody that has done this could show me how to get started and what I will need, I'd appreciate it greatly. Thanks.

You will need to remove the PS pump and the bracket that holds it. Get the items I mentioned before and put them in in place of the existing one, (4 bolts). If you have A/C the compressor mounts on the new bracket just the same as the old one. the only difference between the stock Ford Bronco bracket and the Saginaw (stock Ford E250 bracket is the mounting holes for the PS Pump).

In reference to the shaft bushing, I was referring to the one in the Saginaw pump, but only replace it if is is scored up. Scoring is caused by wear and a piece of metal shaving getting into the shaft area which could get pulled around by the shaft rotation. You can not replace the bushing by with out a press due to the tight fit. However, the rest is a 1, 2, 3 process following the instruction sheet that comes with the kit. I was referring to the Saginaw rebuild process for an old one. The Saginaw pump is pretty free of that stuff because it has a magnet inside to collect metal if it goes by. Metal particles can come from the gear box if it is worn, it only takes one tiny piece to score up a bushing. With a Saginaw it would probably go on for years without making a noise, but the Ford pump isn't built as well in my opinion.

It is not necessary to rebuild a Saginaw if it is running fine, I just do stuff like that so I know I'm at ground Zero with a junk yard part. A new one is also an option.

I need to process some pictures on rebuilding, I'll try to post them within the next few days.

Good luck,

Thanks Fred. I'm looking at buying a new pump, and a used bracket. I've seen so many pics of these E250 brackets on FSB... will the only modification be drilling out larger holes on the AC compressor and using larger bolts to mount it...or is there more to it than that? What I mean is, does this pretty much just bolt right up, or do I have to fabricate some stuff? I'm running a serpentine pulley system.

Thanks again!

It is pretty much a drop in for the serpentine system. You may not even have to drill out the holes for the A/C, check before you do it. I have heard that some people have had to change the size of the serpentine belt. can't remember if it is increased a couple of inches or reduced. That should be easy to determine based on the pulley. Oh yah, the pulley - you need the pulley off the E250 because the shaft size is different than the Ford. Grab the whole thing and then you will have an extra pump laying around.

I had to fabricate the mounting plate since I have a V-belt system and didn't have access to the E250 V-belt mount. It was easy though.

Good luck,
