Looking for the large wheel nut size on 2000 Malibu.

HUH?

What do you mean actually? The thread and pitch of the stud for lugnuts?

Nevermind.....I got it. I was talking about the large nut in the center of the wheel that holds the axle in (34mm). Need to take this off to replace a hub bearing.

make sure your torque it right when you re assemble it
