Hello , I have an issue with my 2003 , silverado 2500hd 4x4 system and am wondering if anyone else has had the same issue.

 

I use the truck to plow snow first off. The other night while scraping off the driveways with the back plow the 4x4 would disengage when i stopped on the street to shift into reverse to go back up the drive to scrape it again. The light goes off , the transfer case disengages and the manual shift lever is still in 4wd hi.Sometimes it will come back on by itself or i have to throw it into 2HI then back into 4HI to get it to work. It is also an intermittent thing doesn't do it every time. I had it into the dealer today and the master tech checked the power etc for the actuator and the switch located on the top of the transfer case and said that they are ok. Then i was told that it is probably inside the transfer case. There are no noises , grinding or any other issues with the 4x4 other than the disengagement. He thought it might be the switch losing contact but everything seemed to be working fine when he checked it.

 

Has anyone experienced this before ? Any insight is greatly appreciated. Thanks :cool:

Thanks Daddy for the reply . I didn't take the switch apart i had them replace it same day , the system is still acting up. I think i will do the Actuator before i decide to have the transfer case dropped and looked at. Seems to be that it does it when the truck hits a bump in the road or at the end of a driveway. Any other thoughts are greatly appreciated, Thanks again.

      The Peckish Synapse

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.

      Diesel hit $6.00 here today at the truck stop.   Payed $2.79 for E85 today too.
