Dealer replaced stub shaft and parts listed in bulletin 5653. When that didn't work, dealer contacted Chevy and they said something about probably no clearance between new stub shaft and cross pin when hot and to replace the front differential. I looked at paperwork on repair last night and it listed the differential and also listed a front axle.

Thanks, I have read on others customer work orders about the stub shaft possibly rubbing on the cross pin. I'll mention that to my service advisor and see if they'll replace mine too.

58 pages and they still haven’t figured this problem out yet... I’m hoping to get a 2020 Trail Boss in the near future but maybe I’ll just hang onto my 2018 Colorado ZR2 until the 2021 or 2022 Silverados are out... whenever they have it figured out.

What’s the easiest way to check for those specs while I’m out surfing the Chevy lots, or do I have to use the VIN to find that online?

When you find a truck you like just ask the dealer to pull the Build sheet up. Takes 5 minutes and don't cost anybody anything. Sheet will have a bunch of alphanumeric codes listed. You want Frt axle code SU5 which is the GM sourced axle.

Thanks, I’ll do that.

Hot day/long trip and it's back. Little over 6000 miles since diff. Change.

Test drive a Ford F150 yesterday. Even though nice, still like my Chevy better. May look at a GMC with a su5 axle and be done with it.

I went through this all last year Its the Dog chasing its tail it ALWAYS comes back. Contact the BBB and file a lemon law buyback case its your only ticket to relief. If they repurchased mine for the same issue what makes yours different? They know they are defective.

So to be clear, there has been zero cases of anybody with the SU5 experiencing this problem?

Not that I've heard. Neither of my two trucks, both SU5 frt axles, have made any noise or music.

      Vehicle Payments

      By ChristopherDobson · Posted

      Monthly payment is only part of the equation. With today's prices and interest rates, I'd look at the total monthly cost: payment, insurance, registration, fuel, maintenance, and expected repairs. A vehicle that fits comfortably into your budget is usually the better choice than stretching for a higher trim. I've also kept my vehicles longer over the past few years. New cars have gotten expensive enough that driving one for 10+ years, while staying on top of maintenance, often ends up being the most cost-effective approach.

      OCI, not when but why?

      By Grumpy Bear · Posted

      10 Ford and Chevy engines proven to reach 300,000 miles   You may note a common 3K OCI on this list of gas motors. I skipped over the diesels. Dh'O.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By jake111 · Posted

      Thanks newdude!  By the time manual selection is needed, I'm probably too much of a control-freak to depend on the transmission sensing braking to activate automatic downshifting.  I would be anticipating the situation and already be manually downshifting.   This truck replaced a 2004.5 LLY diesel with the Allison 5-speed.  Putting it in T/H made noticeable differences (when the torque converter locked, upshift points, downshift behavior).  On this 2024 gasser with the 10L1000 I haven't been able to detect much, if any, difference.  Ok, I can never tell now when the torque converter locks up.  But I also don't notice differences in shifting.  For downhills, I've probably already manually downshifted by then anyway.  Since it's also more awkward (than the 2004.5) to engage/disengage I don't even bother.  Or maybe it doesn't really matter with just a 3k lb. camper in the bed?   Thanks also for the list of reasons the charging system might select various voltages.  However, what I am seeing doesn't fall into any of those categories.  It very definitely, and very consistently, rises after coasting/braking.  Maybe not immediately, but not very long after coasting/braking.  Very consistently drops voltage when no longer coasting/braking.  It might also be interacting with the camper battery charging (I might disconnect the camper and see if it changes the charging behavior).  I also need to recheck turning on headlights for when I want to force it to charge the camper.   Another JR, in June I converted the camper to LiFePO4.  Since it's not a good idea to try to charge lithiums directly using truck, I installed a Victron Orion XS DC-DC charger (which BTW is AMAZING!!).  Being cheap, I only had to buy that one item (besides the battery, of course) to do the conversion.  The camper OEM 120v battery charger (only 19 years old and works perfectly) and the truck feed the input to the DC-DC charger (not at the same time).  But I didn't want the camper charger feeding back to the truck so I kept the old separator.  I considered replacing the separator with a 30amp diode but that means more work and might add another 1/2 volt drop.  One thing that surprised me was the voltage drop over the long 10awg wire run, so I can only charge smoothly at 8 amps (because the DC-DC charger is completely configurable).  Another reason I don't want an added voltage drop with the diode.  I might also be a little lazy but all this work is being done under the sink with a small cabinet opening.

      cam upgrade in CA

      By davester · Posted

      apparently CA smog is (or at least was)  checking that the vehicle is using the oem and/or a ca smog approved tune, so I expect you'll fail inspection doing it.

      Possible lifter tick after DOD delete

      yes, leaking exhaust will mess up o2 sensor readings, which in turn messes up fuel trims.
