Power steering failure

I went out last night to put the truck in the garage, I needed to turn it around and since there was plenty of snow on the ground I cranked the wheel and popped the throttle to spin it around. Went to straighten out the wheel and… no power steering. It was a spirited maneuver but nothing to aggressive, the wheel was at the lock and I heard the PS pump strain a bit.

 

Belt is good, fluid level good, no fluid loss and no odd noises. I tried to bleed it (jacked up, turn wheels back and forth), no luck. The pump is very quite, like its not pushing any pressure, even at full wheel lock there is no noise from the pump. Seems like the pressure bypass valve stuck open, possible? Could is be an EVO issue, fuse? Could I have damaged the steering box, blown an internal seal?

 

Guess that’s what I get for playin like a dumb kid. :)

the PS pump's drive shaft may have fractured

 

 

 

 

 

I think he hit it right on the head w/ this one...I did the same thing once on some ice and it turned out to be the pump's drive shaft but i suppose it could be something else

Bugger, I wouldn't think it could do that, I would figure there was a pressure bypass... Guess its not idiot proof (me being the idiot). :)

 

NAPA says $113 for a rebuilt pump with reservoir, $46 without. Is the reservoir a pain to switch over? Or is this a part that would be better to get new/dealer?

 

Thanks for the replies

Easy job with the right tools. Get a pulley puller, don't use a 3 jaw puller unless you want to destroy the pulley.

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      By Brendan C · Posted

      New to diesel trucks. I happened to find my oil cooler leaking oil externally with only 4,000 miles on the truck. I didn’t realize this was an issue until I started researching it. Dealer is going to replace it under warranty but I’m wondering if there’s anything GM is working on to fix this issue. I’ve heard the oil filter used is the same as they use on their V6 motors and that’s what is causing the problems. Should I switch to a bigger filter or keep using the OEM recommended?

      Seems to be Missing a lot of Updates

      By Vu1can · Posted

      So, GMCustomerService:  Judging by the Update History pictured above, is this truck missing any updates that it actually needs. If it's just for the infotainment system, the radio is working fine and no trouble with SeriusXM. and Android Auto is working fine wirelessly with my phone. Some months ago, an update notice was sent to my truck. I approved the update and it finished saying that the update was successful, but it seems that whatever that update was, it didn't actually get installed - at least not if I'm to go by the Update History shown above.   So, again, are there any updates that this truck really should have? I've checked with my dealer but they're reluctant or commit to anything and if I want them to check, they require a $200.00 fee just to check it out and then I'd have to pay for the actual update(s).    Ignorance is bliss, and if none of the updates goes to fixing any mechanical discrepancies, I'll just leave things as is.

      Electrical Problem - solved

      By CNH-320 · Posted

      Hey everyone, I recently had an issue with my 07 2500HD GMT900. My DRL’s stay on at all times. Right front turn and right mirror turn signal indicator stay on solid at all times. By “at all times” I mean the only way to make them go off is disconnecting the battery. I tore the headlight assemblies out, tried disconnecting the harnesses to eliminate bad wiring at the harness, I unplugged the headlight switch, no change and the mirror turn signal still stayed on. My first thoughts were : Bad bulb and/or socket somewhere, under hood fuse panel bad, bcm bad, tail light or trailer wiring problem, or some random short to power in the harness.  Possibly a bad ground but unlikely. I had a big clue in the fuse panel, it had a burnt smell. I started pulling every fuse that had to do with DRL or right turn/park lamp. Nothing made the right directional turn off but pulling the DRL2 fuse made the DRL’s go out.  After studying wiring diagrams, I found that both problems had that fuse panel in common, the bcm also controls both problems but knowing the fuse panel had a burnt smell I removed and disassembled the fuse panel and found a little corrosion on the printed circuit board.  I ordered a new fuse panel from Amazon for like $260. When it arrived I installed it, and put everything back together, the problem was fixed. I figured the fuse panel needed to be replaced anyway so that was a logical place to start. Hopefully this story helps someone in the future. Regretfully I didn’t scan for codes before I did everything.

      That stinks. I’m sitting on the side of the road right now with the same issue. Never had an issue before taking it in for the ground strap recall. Now I’m outside of warranty and they’ll probably want $200 just to diagnose what they already “fixed”.

      I wonder kind of nuts and bolts they will come up with next? Jim
