I have been looking for the amount and location of all my grease zerks on my 07 Silverado 2500HD DMax.
What I have found:
Each year make and model may differ in one way or another depending on the year and the model.
Refer to your owner's manual, is the column response.
This is what I found in my manual and the GM website.

Lubricate the front suspension, steering linkage, transmission shift linkage, and parking brake cable guides. Control arm ball joints on 2500/3500 series vehicles require lubrication but should not be lubricated unless their temperature is 10°F or higher, or they could be damaged. Control arm ball joints on 1500 series vehicles are maintenance-free. Vehicles used under severe commercial operating conditions require lubrication on a regular basis every 3,000 miles (5 000 km).

Your best bet is crawl under your rig. Get comfortable. And start looking.

Great info thanx for the heads up and helping others who may be wondering..btw..i hand crafted that motor with love

Ummm ??? You hand crafted what motor?

i worked at dmax for 5 years making the duramax motor till i got laid off

OH !!! That's cool I get to meet one of the many, that has given my truck life. (not too many people can say that LOL) Well you will be happy to hear it hasn't given me a minute of problems. It's been VERY reliable. As for the rest of the truck... Well it's the typical usual stuff.

good motor made by people who care..i can tell ya what all those blue, white, pink, yellow and green dots mean too

Well I crawled under my truck with my grease gun and a flash light.
I found 10 grease fittings.
Lower Ball joints L & R =2
Upper Ball Joints L & R =2
Tie Rod Ends L & R =2
Inner Tie Rods L & R =2
Idler Arm and Pitman Arm =2
Total 10 grease zerks

I'm still a little concerned I didn't see a #11 grease zerk
I looked on the drive shafts, steering column, shifter linkages.

The one you missed is on the Idler Arm.

The Idler has one on the linkage arm (same idea as the pitman side) and one on the top end, feel with your hand - it sticks straight up

So, if I ever buy a Duramax, and it fails, I'll go take out my anger on koolz71- except Duramaxes never fail, so he's safe...
