Titanbuilder Posted July 16, 2019 Share Posted July 16, 2019 I have a 2006 CHN and the front hub caps have no plug or window to check oil/grease level. They are made like a fruehauf trailer hub cap with threads an screw in, looking for something to replace them a window/plug. Also does anyone know the size socket to remove the caps looks to be 4 1/2 or so,thanks.
