Im blown away with how many service reps  / dealers dont have a clue about greasing the front end zerk fittings on the 2500 HDs. Thank goodness the dealers 1 "Diesel guy" knew . Why is this? Id imagine most folks dont know so they dont ask for it etc?

99% of the rest of the GM lineup doesn't use them anymore, so the lube techs are often blind to them.  The 1500's haven't had fittings since 2019.  The 2007-2018 1500s they only used fittings on the outer tie rod ends and everything else was sealed. 

 

Other HD trucks on the market (Ram and Ford) don't have any to begin with either, so nothing to grease on those.  GM is the only 3/4 and 1 ton truck left with grease fittings on front suspension components.

yea , I understand that but the 2500/3500 still have them and i just felt more than 1 person at a dealership should know this...  at least the service rep had a good attitude about it and said he learned something new . Hes been there 5 years tho..

I haven't been bringing my chev 3500 to the dealer or anywhere else for that matter for service since I prefer to do my own oil changes and greasing so I know its been done and I know what oil actually went into the engine etc and that no one had "checked" my air filter for example and loosened the intake duct hose clamp off or stripped out the screws that hold the cover on into the plastic housing below, or installed the filter sloppily and is now allowing dirt to pass by the filter for example ( l live on a gravel road in a rural farming area ... I farm after all ). I just don't trust some of the staff that work those bottom of the barrel positions in the lube bay. 

 

Service reps are typically not mechanics and they are reading what is in front of them on their computer, I am sure some have quite a bit of knowledge but there would be enough of them that certainly wouldn't have a clue. So then it comes down to the person in the lube bay and how the shop itself views the whole thing, do they credit the lube tech for doing a grease job on an HD truck vs a 1500 that has no zerk fittings .. good question. Certainly not every truck owner would even know if their own truck had grease zerks or not because many people do not work at all on their own vehicles and rely on a shop to do it for them and hoping they are doing a proper job of it. I've certainly heard the comment before from GM HD owners clued into the fact that the dealer was not greasing their truck during an oil change and so had asked why not ... the answer in one instance was and of course that would be from a service advisor was "oh that's not part of the oil change package". 

 

So the long and short is one has to know for one thing that those zerks exist and then each time one would bring it in if it was a GM dealer or some other shop, to specify and have them put that in writing in their system that the customer wants all steering/suspension grease points greased. Then look after the fact to see if anything was done, which goes full circle to why I skip all that crap and just do it myself or as long as I am able to anyway.

Serviced my 2024 over the weekend and I hit the grease zerks with a couple pumps each. I try to do them every 10,000-15,000 miles. usually every other oil change.

 

Made a quick video pointing them out for anyone interested. Hope it helps.

      MPG at 600 miles

      By Chuck FB · Posted

      There are probably a few threads talking about fuel mileage but this one seemed to fit the stats I have seen based on my typical local driven route but with different outcomes based on different seasons/temperatures. I have a few hundred pounds of items that consistently ride on the truck at all times such as a bak flip cover, rubber bed mat, tools and extra fuel so I would be something over 8100 lb without me in the truck. All these examples are based on a 100 mile round trip to a town plus running around town so maybe 110 to 120 miles in total for a trip. Using regular fuel and I assume it always has some ethanol in it but don't know the percentage they blend in. Also speed wise I am going at 62 mph and non aggressive driving although less speed yet if its crappy winter condition roads. I am going by an initial reset of the computer generated fuel use numbers averaged over a couple of thousand miles or so for each weather/season so they may be more optimistic then actual hand calculated numbers. Basically this is painting a picture of doing the same drive but seasonal conditions and temperature being the major variable to the end result. Oh and although I am in Alberta Canada, I am converting it to miles per US gallon so there is no confusion.    So winter time it gets cold here, no real surprise there and the roads can be clear at times but also often have packed rough snow or are are driving through loose snow ( they do a poor job of plowing the highways ) and yes this includes the extra idle engine time due to trying not to freeze ones butt off. 12.7 mpg is what I was getting during the winter months on average.    Then during the spring when it was around the freezing point and the highways are clear of snow, I was getting around 14.25 mpg.   Summer time, I have been getting around 15.15 on average but certainly some of the trips showed quite a bit better fuel mileage, so much depended on how much or little I had driven around town and number of engine restarts after sitting for a while at each location. But stating a best fuel mileage trip to town pretending that is what the truck gets on average is fooling ones self for sure !.      As I said in a different post, I had driven a 645 mile trip over a couple of days stint to a different destination then these other daily to town examples above, and was done during the summer with nice weather and not bucking a head wind, also keeping at 62 mph and its a rolling landscape type highway drive ( this isn't southern Alberta or Saskatchewan flat lands ) Hand calculated fuel mileage in this case though and it came out to 17.65
