I got under my truck to do a normal oil change / Lube when I went to grease my 2 fittings. I greased the first one with no problems, then I reach to grease the next one and...realize that it is no longer there. So I go to Napa to buy a package of grease fittings, but nobody there knows exactly what size I need. I figure i'll have to unscrew the other one to find out the proper thread size. I was wondering if anyone here had any idea what size it is. It'll save me some work.

Thanks for the help,

Where are the two fittings located??

 

STANDARD grease fittings come in 1/4-28 or 7/16-something sizes. All I've seen on vehicles is 1/4-28.
Hope this helps,
