Hi Guys! I just hit 36,000 miles on my 08, so, that means no more bumper to bumper warranty. I was wondering what you all have that you keep an eye on. It is an reg cab long box LS, so not too many frills inside, just power locks. And both actuators have been replaced already. It is a 5.3L with 4L60E. I have the 5 year 100,000 powertrain warranty. I know it covers the obvious, trans engine etc. But what else does it cover? Powertrain is sort of vague. To me anything that makes it move is powertrain, axles, engine, transfer case, trans, cv-axles, wheel bearings etc. I know about the brakes, trust me! This thing has been in for brakes so many times it is not funny. But, dealers have just turn't the rotors twice and I have replaced the drums already, they were out of spec and could not get them in spec without going below minimum spec. So, I bought a new set of drums from Advance and so far they are ok.

 

Any other issues or anything? So far it has been a headache truck, transfer case was shot from the factory, first time I used it I could not pull the lever back. Looong story there. And brakes another issue. Engine oil pan gasket replaced. Door actuators. But I still LOVE this truck. It is the best truck I have had so far! (Despite all the issues). I hope I am getting all of the bugs out of it. I hope they all are out now. Any kind of maintenance you guys would do? In the manual it just says oil change and check things etc. I have not changed oil in the axles, trans or anything. The transfer case was done when it was rebuilt by GM. I put the trailer tow kit on. Trailer receptacle, trans cooler and a class 4 reciever hitch. The tranny cooler is very large and keeps the trans fairly cool towing my 16 foot tandem axle aluminum deck over trailer. More or less a ATV trailer. Weighs 1200 empty.

 

Well, thats about all I can think of. Let me know what you all think on what to check for and what maintenance items to do. Thanks in advance for any info!

Well, these trucks are known for Rear main seal and transmission seal, so keep an eye on that, along with a leak from the power steering pump lines. Other than that, not to many issues to be worried about. :lol:

Thanks for the reply. I would think those 2 things you talk about should be covered under the powertrain warranty I would think. I too haven't heard of too many issues. Heard of 1 or 2 situations of heater cores going out, but that was early in the trucks life.

There's always random stuff, and your right, they ARE covered items under the power train.

If you have not already, time to flush the tranny, replace the front and rear diff fluid, and transfer case fluid. You can also change the plugs if you are like me and don't believe in 100k spark plugs. Maybe consider flushing the brake and power steering fluid while your at it.

My '08 has 45k already. I got most everything fixed while under the 36k warranty, not much else wrong by this point...bugs worked out hopefully.

 

Just drive it and do all the major services at 60k. A tranny flush at 36k is overkill IMO.

I wouldn't worry to much your trucks just a baby yet. Id just keep up with the regular and preventive maintenence.

I am about at the same mileage, 33k. I read the dexcool thread last week about flushing coolant every couple of years.

 

When are most people needing to replace their rear brakes/drums? I just had my rotors turned under warranty.

 

Other than that, anything else to look for? It seems that a lot of people recommend much more rigorous maintenance than is indicated in the owner's manual.

If you intend to keep your Truck past 100,000 miles then you can't do enough preventative maintenance.

I don't beleive the power steering is covered, at least it wasn't on my buddy's '08 Yukon (With about 65,000 km/just over 40,000 miles)

What to look for at 36k? About 100,000 miles of troublefree driving. Oh, and remember, these trucks are known for needing wiper blades somewhere around 50k

Yes, I'd like to get as close to ten years as possible out of it, which would put me at about 150k. Anything in particular for the 5.3L or the tranmission?

 

My last car was notorious for timing belt tensioner failure (interference engine...yikes) and engine sludge so I paid special attn to those items.

Beware of the fuel pump if you routinely run to 1/8th of a tank....though the pump is covered under the power train warranty. Then you will be hit and miss on those pesky GM electronics, like power window actuators, switches, navi. Hit an miss, but between my Vette and my truck I have had more issues with electronics than anything else here in the south. (had failures of Door locks, Actuators, Navi on both around 36K...though that is closer to 3 years for me since I don't drive much).

Thanks guys! Wipers at 50,000?????? Try 25,000. Mine were toast. But I do live in WI and we get ice, snow and lots and lots of rain lately. I am thinking of doing the diffs and trans @ 40,000 or 45,000. Otherwise, it sounds like these are decent rigs for a while, I hope! I know my 02 started taking igniton switches out at 50,000 and then every year after that. Which is why I have my 08. No one could tell me why they failed. There has to be a reason. But, I hope this one is good to go for a looooooong time!

      The Peckish Synapse

      By Grumpy Bear · Posted

      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.
