Cracked Transfer Case

My wife came home from having her 2003 GMC Yuon Denali XLT serviced. After the oil change and routine maintenance, the Service Tech told her she had a cracked transfer case, but they did not do it! This vehicle has about 52,000 miles, never driven off road and is far from being abused since we purchased it new.

 

I know nothing about transfer cases and before I go to the dealership, I was hoping some members could provide me with some insight or useful tips on what I should be looking for, or what I should be asking the dealer prior to opening my wallet.

 

Any help is appreciated!

I would take a look and see for myself. If you had a cracked transfer case you would have heard noise coming from it as it blew apart due to fluid leaking out. Have you noticed any fluid coming out or ever seen any wet spot but didn't know what it was? Make sure it isn't a weld line or a scratch/scrape that is msconceived as a crack.

I had mine replaced under warranty, It had a crack around the rear yoke seal I believe is the name of it. Anyways I never noticed the just kept changing the rear seals because they would see the leak. After 3 seals someone finally noticed. Anyways hope you have warranty I know it's not cheap. I will comment that I ended up having to replace the seal on the t case a year later out of warranty. which wasn't that cheap either.

My brother had this problem with a 2003 Dodge ram. the dealer replaced 2 t-cases and both u-joints on the driveshaft. He bought the third when his warranty ran out. turned out his drive shaft was out of balance, but his truck has been offroad. Hope this helps.

Yeah, drive shaft out of balance is the thing I can thing of that would cause this. T-cases are very strong so if you snap one just by the way you are driving then you have a major problem. I'd say it's either been hit by something or your driveshaft is out of balance.

The new GM t cases suck, big time. The newer ones are aluminum, any real off roader will tell you that. There is no way you can compare todays t cases to a np205. You should not be breaking that case unless your beating it. I had cracked mine, but off road like its going out of style. You may also want to check if you drive at high speeds in 4 high. That will heat the case up and crack it. Not common though, but it has happened. If infact it is cracked, you should see fluid everywhere, maybe not on the ground but covering the whole case. Fix it before it gets worse!!

      My brother has an Escalade. The warranty has expired so he told his wife to go to the Valvoline quick lube he uses some times. They told her if her car was a 2020 and newer 6.2 engine they wouldn’t touch it. Hers is a 2019, so they did the oil change.

      The oil filter has NOTHING To do with oil leak. GM sources parts from 1,000's of vendors and as with anything mass produced, flaws are unavoidable.    Putting a larger oil filter will do nothing but satisfy emotions. The OEM filter is designed for the engine and perfectly capable of handling the demands on the engine. Oversize oil filter could result in reduced flow and overall lower oil pressure.

      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.
