New to this thread and just got done with doing my own first oil change and service.  Great information here on locations of grease fittings and grease to use.  6 of the 9 fittings are not bad to get to.  The remaining 3 took me much more time than I wish to spend on a quick grease service.

 

Couple things I changed on my 2020 GMC 2500HD to help:

To eliminate the need to come from the top of the pitman and idler arm at the center link, I changed the straight fittings to 90deg.  Pointed the grease fittings towards the outside of the truck and now both have very easy access.  Standard 1/4-28 taper thread grease fittings.  No clearance issues while turning.

  • (1) top of pitman arm at the center link side of the arm
  • (1) top of idler arm at the center link side of the arm

To eliminate the need to remove the skid plate or struggling to fit arms in places they don't go, I installed a hose kit from Moog.  Part number K6714, purchased off Amazon for $16.28.  Grease fitting end mounts to one of the sway bar mounting bolts.  Clean looking install.

How did you guys get the "idler arm???" on the driver's side?   There is some type of module that is in the way of my straight fitting on my grease gun.   I was able to get them all, but the top passenger side rack fitting was a ******.   I looked like a coal miner after I finally got it.  

 

Like others have stated, mine took 6-8 pumps per fitting.  I've owned the truck for about 14 months.

If you found 8, you are missing one.  Should be 9.

The fuel filter has a drain.  The center of the filter cap opens up.  The Duramax supplement manual shows it in there.  Its under the "Water in fuel" section.

The arm on the driver's side would be the Pitman Arm.  Idler and Idler bracket are on the passenger side.  The "module" is probably the digital steering assist module. 

 

Its a tight squeeze especially with the diesel engine.  I've always pulled that front plastic shield loose or removed it and you get more access.  A 90 degree adapter for the gun might help it too.

So, just called my dealer and, specifically asked if they grease all the fittings. Told her I had a 2500 HD. She said, that if they had fittings, then they are greased at every oil change. (5,000 miles) I told her that the HD trucks do have them still. (Evidently, some newer model cars I guess dont?) At any rate, I looked at my last service bill and it stated "lube, oil & filter" then one of the boxes that were checked was a "Lubricate Chassis Components"

So, evidently they have been greasing all 9 fittings. But, I like the "trust but, verify" - rule of thumb 

I'll just take a look see next time I'm at the dealer to see if they really are doing it.

Just go under the truck. If they were lubricated, you will see fresh grease on the zerks.  Unless they wiped them clean. You should still be able to tell.

I would go to Vegas and bet a lot of money that very few dealers grease all the fittings on these trucks. I have some experiences that back this up. Years ago I sat and waited on a warranty repair on my truck. I was there about 4 hrs. I sat across from the open door on the lube bay. A steady stream of vehicles passed through. Occasionally the tech would check the air pressure in 1 or 2 tires (pre widespread TPMS days) and never did I see anything on any vehicle get greased despite the fact that several of the vehicles were known to me to have greaseable front end components. Neither did I see any of them get a differential fluid level check or a transfer case level check. 

I had a friend with an S10 4WD that needed lower ball joints around 50k. They were bone dry and he used the dealer for oil changes (they were hard to get to on this truck) 

So unless I greased them myself, I would assume they hadnt been greased. 

 

I also noted on the 24's that the grease fittings have a different thread than other years. I had a supply of 90 degree fittings that I had used on other truck to make access easier. I had even used some on my 2021 HD but they would not fit the 2024. I didnt feel like it was worth going through the hassle of sorting out the new thread size so I just went ahead and greased it as it was. Pulling the splash shield is crucial to the access. I added 4 or 5 pumps per fitting or just until I saw the boot start to fill.

All these ball joints are designed to survive without greese.  We have great debates if we should remove the zerks but you guys would throw a fit so we let you pump until your heart is content.

The likelyhood that whatever supplier GM uses is sending them a vastly superior product in todays world is slim to none.

      What I think you're saying is there is supply here at home, and in Venezuela, and we could ease pricing if only it were favorable to do so.   Well, yes?   But that's not the current market. Supply isn't what could someday exist, if only, it's what producers are willing to produce and sell at a certain price point.   The national price of single family homes would come way down if we'd just slap together a few million homes this summer.   RAM and GPUs would get a lot cheaper if we just set up some factories to produce a bunch more and stopped using it to build out AI data centers.

      The turn signal/multifunction switch is faulty.  I've seen a few of these go bad at work.

      If we actually used any significant amount of that source in the USA then I'd agree but we don't. We've had that discussion before. We drill and pump more than we use. Thing is, we sell. We export. Gas and Crude. It's more profitable so any shortage here is self inflicted and LEGAL.    I worked a gas plant that has multiple fuel sources available and I worked in the furnace and boiler plant in that facility. I'd had days we swapped fuel types four times in a twelve hour shift which isn't done on supply but on margin. Two of the fuel sources are internally generated. Tail gas and DAK, both of which are sold as well a consumed. We always had more than we needed to run the process but we chose the fuel that produced the best margin not bought at the cheapest price always. A good bit of math to that and back in the time that was done on a slide rule.     I worked the Shale Oil Semiworks of Chevron Research and CONOCO Research in Salt Lake City. That process never went into production although it was very successful. Why? Did we lack oil bearing shale? Nope. Price of crude never made the margins work. That was in the late 70's early 80's. Remember history? What was happening then was a reaction to that situation. It didn't drive it. If so then it's easy. This isn't a supply and demand thing. This is a profit and margin thing and AI rules that now.    In no refining situation that I was ever in would a bomb hitting a well anywhere in the world 'instantly' interrupt or even distress the supply. Most plants have more than a months worth of crude in the tank field and more in pumping stations. That yo-yo could play out over days, weeks and maybe months and have zero impact on plant operations. How many times has this been off and on in the last few months? These people and not stupid. These plants measure down time in hundreds of thousands of dollars per day. They are not sucking fumes or waiting on the next truckload with baited breath. Besides, as I noted, they are for the most part 'vertically integrated'. They own it from the dirt is sits in to the delivery rack and sometimes to the pump. It has a HUGE shock absorber built in. When production suffers, refining wins and when refining is winning exploration is killing. The rest of that crap in the news is a 'news cycle'. Government dipping in to reserves? Oil is stealing their milk money. There's a reason Chevron abandon Venezuela infrastructure and it had nothing to do with security of US citizens. Nationals run those plants. it has to do with MARGINS disappearing to corruption. They are in no hurry to return. Is there supply there? Oh yea. More than enough to offset what is bought in the middle east. Just isn't ???? Profitable.    We have supply. There are places in Illinois you can drive a pipe into the ground and run your homes natural gas furnace on it.    A refinery fire will gum up the supply works but not a localized war where the market is using a limited supply from. Now Europe, that's something other....
