I have a 2015 Chevy Silverado single cab short bed work truck with the 4.3 liter that the power steering unit just decided to quit working while prerunning in Baja with my wife. It wasn’t an issue but my triceps got a serious work out. I took it into Bob Stall Chevrolet in La Mesa California and found out that the ECU and the EPS weren’t communicating. Of course this isn’t covered by the warranty and it was $1,100 for the new EPS and $800-$1,300 for the labor. The gremlin of Offroad racing usually ends up being an electrical issue so I decided to ditch the EPS and go with the older more reliable Hydraulic Power Steering Steering. In order to do that I ordered the Dirty Dingo Power Steering Conversion Brackets, Dirty Dingo LS water pump adapters, LS water pump, 1996 Chevy Silverado Power steering pump, 2006 Chevy Silverado hydraulic rack and pinion, and Corvette vacuum pump block off plugs. All the parts finally arrived today, and I’ll be starting this project and hopefully be finishing before the weekend is over.

Sorry but why. There is tried and true systems. Full hydraulic systems that are stronger then coffin nails. And half the parts.

Electronic power steerings a joke. The steering rack and pinion is temporary, I’m designing a swing set full hydraulic system with a Howe hydraulic ram. I’m going to need a power steering pump so this is a step in the right direction for me.

After battling with the hydraulic power steering in my 93 C1500 years ago, having electric power steering is a godsend to me. My problem was that the only pumps available to me at the time were remanufactured and one summer I changed that pump 4 times in 3 months. I could still, to this day, change out the pump in that truck blindfolded. I did it probably about 7 or 8 times total in the years I drove it.

The hydraulic system in my GMT800 Tahoes was pretty stout. Never an issue, but eventually they'll spring a leak.

I don't drive Baja though. [emoji2369]

I agree. Buy yourself an AM only radio too, in case the modern stereo goes out.

If it were a daily driver I’d get the electric power steering completely. But several of my buddies also had EPS fail on there trucks that never hit the dirt. One of them had to change out the whole rack once and the motor twice. Every auto parts store has power steering fluid and some sort of power steering line I could mcgiver. But a Snap in diagnostic machine is a little tougher. This is my fix to the the problem, other people have there’s and I respect that! Thanks for the reply

There are ways to harden electronics to shock and vibration, I assure you. And we've done it with systems that are far more complex than a power steering system.

Haha I have racer x intercom headsets in the truck just in case that happens!

 Agree with you 100%. I’m going to something I know just for the simplicity of it and what’s been proven in Offroad racing since it started.

If you have sponsors with deep enough pockets, I bet that I and a couple hand-picked guys could design and build you an electric one that's Baja-worthy! [emoji106]

No sponsors or deep pockets? I know Polaris RZRs have EPS but I haven’t seen a desert truck with one yet. It’d definitely be cool to make it work

It was worth a shot! Good luck on your project.

I would be very leery of using 90s truck parts though. The trucks then (1500s) were not as heavy as they are now.

      Anyone had to replace their Onstar module a.k.a. Telematics unit?

      By davester · Posted

      Hasn't come up in the 3 gm forums I follow. And only gm knows the frequency of failure of that part. LMG, you want a recall so it's replaced for free...

      Transmission Woes :-(

      By newdude · Posted

      You need a better code reader/scanner.  You are missing codes.  Did the dealer give you a copy of the SAVI scan from that visit?     If the fluid hasn't been changed, change it.  Shudder will likely go away.

      Can anyone decode a VIN to determine if this truck has had emissions issues or a recall?

      By newdude · Posted

      TLDR to my other post...   Hard. Pass.  Too many what ifs.     Are you set on a 3.0 Duramax?  Have you considered anything not GM just in case?  If you don't have to have a pickup, lots of other options for $27,000 out there.

      I see some red flags.   - No mention in the Carfax if the oil pump belt was changed.  LM2s had a 150,000mi service interval, and its got 164,245mi on it.  So right out the gate it needs about $3000-3500 for that to be done before driving it another 150,000mi.  Belt is at the rear of the engine.     - If something happens to the transmission valve body, the special coverage is expired by mileage.  That will likely be an out of pocket expense, with zero or near zero GM participation if something happened even though its in by time.   - 2020 LM2s seem to need timing chains after 80,000mi at some point.  They fixed this end of 2020/starting 2021 model year engines.  They will usually set a P0016 I think?  There is another $8000-10,000 if it needs a chain.  The main chain is at the back, secondary at the front so the pump belt would be done at the same time if it needed chains.     - Long oil change intervals.  7,000-8,000mi on average, probably close to 0% or perhaps to or beyond 0% on the OLM.  Lots of them not at the dealer which makes me wonder how much of the oil ran through that truck was the proper Dexos D rated 0w20 oil and not just gas engine 0w20, which is not the same at all.     - Long fuel filter changes, again likely taking the fuel filter life to 0% or more.  First one went 28,603, second was done 43,094 miles later at 71,697, from there another 46,452mi to 118,149mi, and then the most recent one 37,026mi later at 155,175mi.  So counting its original fuel filter, its had only 4 fuel filters on it.  No bueno IMO.         Good news?    - It has had only two warranty trips to the dealer.  The first free service (end of December 2020 on the Carfax), and the transmission reprogram recall (end of August 2025 on the Carfax).     - Truck did a LOT of moving, so that might explain the lack of emissions related repairs like bad NOX sensors, bad exhaust temp sensors, bad glow plugs, etc.         The "emissions system checked" could just be how something was flagged for Carfax.  GM dealers have to do SAVI reports for warranty repair orders so they scan the truck.  So its possible that is there for that?

      Thank you, @Z45!   NOTE - No all repair shop/Dealers reports to Carfax   That is my main concern.  The CARFAX looks way too clean for a 6 year old anything with 164,245 miles.  Even something known for reliability (like many Toyotas) typically has a lot more replaced, like a Nav screen, interior trim, shock/strut, or brake pads.  And surely the last set of tires (installed at ~58k miles) would be bald unless those were all highway miles.   I'm tempted to pay a local dealer to look up the VIN, but am not sure if that will be worthwhile.  Last time I did this, it was 100% useless, and I felt scammed - they noted the bumper was replaced years ago and that's it.  A 5-year old could spot the accident damage, even though nothing was on the CARFAX.   After giving the dealer a call, the truck may have a hard shift, but they have to verify with their mechanic if that's even a concern.  And I've test driven about a dozen of these now, many near Chicago, and half the trucks shift hard/odd at all throttle positions.  The ones with aftermarket lifts/larger tires shift terrible, and 3 stock trucks shifted so violently I thought the transmission valve body was going out.   At this point I'm conflicted, as I need a vehicle, and am coming up short locally.  Northern trucks in this price range tend to have either multiple owners, a lot of mods (lifts/oversized tires without re-gearing), and are generally in rougher shape.   If this truck showed up in your neighborhood for $27k and you had to purchase it sight-unseen, with the possibility of needing a 10L80 rebuild, torque converter, or rear end - would you do it?  I'm convinced most of the 10L80 trucks I test drove are broken, they can't all shift so bad, with massive flares/slipping/lurching and mis-matched downshifts like a teen driver learning stick.
