GMC Accidentally slipped into 4 wheel drive

I was towing my 24' boat with my 2014 GMC Sierra truck in 2 wheel high (I rarely use 4 wheel drive).

 

Unknowingly, it slipped into 4 wheel drive as I'm driving 65 + miles per hour on a dry highway.  I finally realized something was wrong as I noticed an unusual humming noise and I could smell oil burning?   

A repair shop told me the truck was in 4 wheel drive and the front left gear oil must have overheated causing it to spew out (causing the burning oil odor). 

Their inspection also revealed that the front left gear box bearing was damaged and loose; obviously damaged due to loss of gear oil!

 

The repair guy told me that he had seen this problem before!   Makes me wonder if it is a defect with the GMC?

 

Has anyone ever experienced, or heard, about this problem occurring with a GMC?

Read the first sentence

 

Not reading the rest

 

get rid of the cursive, it’s annoying to read, and it’s annoying to think about what kind of person would intentionally switch the font on a message board.

You sure you didn't rotate that knob instead of the headlights?  How many times a month do you engage the transfer case in all of its modes to keep things from getting stuck due to lack of use?

The only thing that can really be damaged would be the transfer case or CV shafts, if it was locked into 4x4 part time and you were driving on dry pavement for an extended period of time.  This does not all add up.

      Gas Prices

      We drove about 15 minute east today to visit a friend and saw a steep increase in price in the same county. About 50 cents a gallon steepper.

      Wow I'm in a pickle. (Broke down truck) and a story.

      Sure about that? A degree wheel and a dial indicator would lower your degree of assurance in that statement. 😉    It why we have offset keys and dialable timing sprockets. Just say'n.... I've built a few and have never seen one "On the money".

      Tire psi

      By Chuck FB · Posted

      I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back.

      No Software Updates - Old Build

      By TrueBlue · Posted

      That part I understand, that the dealer can do it. But I'm not understanding why updates that were available to the truck since it left the factory, or the dealership originally, would not still be available to it without dealer intervention.   I'm thinking along the lines of recalls. They stay available until they are completed, regardless of whether they are in warranty or not, or in the hands of the original owner or not. Why not updates as well, especially since some of those can be safety related also?
