On this one the Allison filter was on far tighter than necessary and took a fair amount of torque to break loose.

I greased the fittings in front and the three center ones were far easier to access after removing both the front shield and the added Z71 package skid plate. None of the zerks showed any side of a grease gun having been near them and the boots were empty. I don't think I will be using any of my "free" oil changes given the lack of proper PDI maintenance.

Someone tell me more about the grease requirements on the 2018 GMC 3500HD. I have not had to use a grease gun on a vehicle for years. This is my first 3500HD.

Would someone post location of the 9th grease fitting zert. Do I need to remove the skid plate in the front to get to it?

I remove the front skid plate and have replaced both of those fittings with either a 45 or 90 to allow access. If you don't replace, you will have to turn the wheels to the right for clearance on the driver side fitting. The other side was too close to the radiator fitting for me to get the standard grease gun end on it.

Good luck.

L5P GMC 3500HD Upper idler arm grease zerk is accessed by removing the plastic engine splash pan, 4 each 15mm bolts. Location passenger right front, Use a 90 degree adapter on your grease gun. Mine showed no sign of being greased by the dealer since the truck was sold to me.

Iím reading this and thinking ďreallyĒ..!!
 
Itís hard to think and believe truthfully that dealerships donít go through these and ensure the front end of these very expensive trucks arenít greased ..! Driving around on dry joints just canít be good and should cause excessive wear ..! I just had my first ďfreeĒ oil change and I wish I read this prior to that because I would have been under it checking on that ..!! Wow..!

They don’t care simple as that! I only use my new truck to go to my house in Maine,and every time I come back I have issues and some will be addressed some blown off, can’t duplicate. It’s just a matter of wearing most of us down so we live with it or forget about it. Mine goes in tomorrow for service Stabilitrak,Service trailer brakes codes. And the second time for transmission lines rubbing on bracket behind grill. I gave up on the piss poor paint on a black Denali.
