Drivetrain Lubrication

[Justinj360]

I need to know, are there any grease points on my drivetrain on my 2004 GMC Yukon AWD? Or places that need greased every so often or they fail? My U-joints don't have any grease points so I'm wondering where you're supposed to grease the parts. I want to keep my truck running well. Thanks in advance.

Only front suspension have zerks, not typically along drive train for our series.

That's kinda what I figured. What about with the transfer case? Anything around there to grease?

We hav e a 4x4 so our tc will be slightly different. IIRC none of this series of trucks have zerks along drivetrains components unless customized. I cannot speak to the 2500 or 3500 series though. They might have ujoint lube points IDK.
