I have a 2004 GMC Yukon Denali and I would like to know were i can find out were all my zerks are and how many I have? I am also not sure what one looks like? Thanks for all your input!

Zerk #7, the Upper end of idler arm mount is a real pain to get to. Like the link mentioned, I also swapped it over to a 90 degree zerk and this worked much better.

Can I just buy one of these 90 degree Zerks at an parts store?

Yup, that what I did. I removed the old zerk, wrapped the area with a plastic bag to prevent crap from getting in the hole and took it to a parts store to match up the thread size. The new one just screwed into the hole and it was good to go.

Do you remember what the thread size was?

Are they metric threads?

I cannot recall the thread size, and I cannot remember if it was metric or not. I just took the old one in, showed it to the guy and asked for a 90 degree one of the same size. He found one in his stash of zerks and away I went.

I am pretty sure that all bolts and nuts and everything else with threads on these trucks are metric. It simplifies a lot of things. It was ridiculous when GM mixed SAE and metric fasteners on the same car in the 70s and 80s. I hated that 15 mm alternator belt tensioning bolt on my '77 Camaro and '83 Pontiac Bonneville. with almost all other bolts being SAE.
