Someone forgot to assign someone to lube these things as they come off of the assembly line.  Very sucky.   I can understand leaving it slightly not completely lubed to prevent pressure bursting or whatever depending on altitude or things that might happen when loading/unloading from carriers.. but at the same time, I don't recall any of the dealers I worked at or went to checking chassis grease as part of the pre-delivery stuff. 

Fwiw, I did notice pale blue marker dots on some of the joints.  The pic I took of the lower ball looked like it had a spot of grease.  I wiped grease away with shop towels while I was greasing them.  I had to go back after looking at the pic I took and tried wiping it again, looked like I missed some grease, but it was a pinkish red marker dot.  

 

So at the very least these were marked off for something.

I will say all of mine seemed to be pretty dry/the boots felt completely empty.

Does anyone have a photo of the lower ball joint fitting.   I'm 99% sure mine isn't serviceable. 2020 sierra 3500

I crawled under my 2020 Sierra 2500 this afternoon after coming back from my complimentary oil change and lube. I was only able to find 7 grease fittings.  I'm with you.   I dont see any on the lower ball joints.   I'm guessing my total  is 7?   BTW the dealer did get the zerks, I  could see fresh grease.

ok--- didnt notice the post with the photo of the lower ball joint..   thanks.

What type of grease are you guys using? I had ICON UCA's on my last truck and they recommended some type of molly ultra grease.

Eh.. it's not so much a big deal of brand or type unless you live in very cold climates.

Mine is in the dealer shop today for another matter. I asked them to check the zerks as I had "heard" many have left the factory dry. They are going to check them for me.

I believe the manual said NLGI 2 grade grease. I found some at Menards.

Thanks. Seem like I do remember seeing that

13,000 mi and finally got around to greasing the zerks

most of them did not bleed out and started to bulge so I stopped.  I will go at it again next oil change.  Seemed like they were completely empty but I did see some black grease ooze out of a few of the seals so there must have been something.

Chassis Lubricant (GM Part No. 12377985, in Canada 88901242) or
lubricant meeting requirements of NLGI #2, Category LB or GC-LB.

We have had the best results using Schaeffer's #274 3% Moly grease in all applications including wheel bearings. There's cheaper #2 grease out there but grease and oil are always cheap in the grand scheme of things!

The Blue/pink dots indicate a fastener/bolt/nut has been properly "torqued" to spec.

Put my truck on my buddies lift today and hit 8 of the 9 zerks. One requires a 90 degree fitting to get to, so I'll get it next week. There was plenty of room for grease...Glad I saw this post today.

    • Have considered installing a DC to DC charger in your camper to replace your isolator?  
    • Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.  
    • No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.      
    • Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.
    • I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?
