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? -
Whats up guys, hope all you GM people are doing great. Ive got a 2017 silverado 5.3 Broke my transfer case gears around a month ago and tc actuator, replaces the gears with nitro gears and axles 4.11 and a new actuator. My truck is modified so i dont have warranty, costed me a lot to get the truck fixed from the middle east and parts+labor is much more than what you guys pay in the states. Anyway everything was fine switched the knob to 2-auto-4hi all was good on the road, i just kept the thing on 2wheel drive all the time. I drive usually in the desert/dunes and decided not to use 4 wheel drive at all unless im stuck. didn't get stuck for a good while till this weekend, got stuck switched to 4hi light changded felt the car turning to 4wheel and my friend gave me a tow and as soon as the car got out the sand got the service 4 wheel drive message. turned it to 2 wheel drive and light was stuck on 4hi however the car was not on 4 wheel drive ( did some doughnuts to confirm if the car is on 4 or 2 drive. Anyway now the car is back at the dealership and they want to charge me 2500 usd dollars just to pull down the transfer case and diagnose the issue. The mechanic said he assumes its the transfer case clutch.. Wanted to know your thoughts on this ? plus Isnt their an upgraded transfer case and clutch ? or a rebuild kit ? What are my options if i want to upgrade the transfer case if i have any ? tried google and didn't find much. HELP!!!!!!!! -
Hello, Let me start by saying I have almost zero mechanical aptitude. Engines are magical beings to me that somehow have been transported into our world from a parallel universe by an alien race. I once thought I had to put oil into the engine through the dipstick hole... Hopefully that paints a clear enough picture... I have a 2003 Chevy Silverado 2500HD that is having issues with switching in and out of 4 wheel drive. I took it to a mechanic and they told me the Transfer Case Control Module needed to be replaced as it was no longer communicating with... something, I seriously don't remember what exactly they said. I do remember they said it was going to be just over $500.. now numbers, I do understand; and that's a higher number than I am comfortable with. My truck's 4 wheel drive selection switch has 3 buttons (2wd, 4hi, and 4lo). The TCCM for the three button model is over $300, but the TCCM for a 4 button switch (auto 4wd plus my three) is like $160, much better for my numbers. Here is my question... If it's a stupid just scroll back up and read about the dipstick hole; Can I use the TCCM for the 4 button in my truck even though I only have the 3 button switch? Or can I use the TCCM for the 4 button switch and replace my switch with the 4 button switch? The back of the TCCMs appear to be the same, only 3 connector ports for the wiring harness, so I thought I'd ask. In case anyone is cringing over the thought that I might attempt this repair myself, take a breath, I'm going to pay a colleague at work to do the install and hopefully save a little money. Thanks, Chris
