What socket size do I need for a 2009 Ram 1500 Laramie 4x4 5.7L hemi front wheel hub nut?

 

Moving to Fourth gen ram section for ya.

 

Either a 30 or 36 mm socket. Probably the larger. I'd head over to a parts store that loans tools (they actually sell them to you in case you don't bring them back) and borrow one long enough to see what size it is. You can then either rent it or buy it outright. Personally, I usually buy one that I don't have so I have one next time.
