check all the main axle housings and one the front on... i pulled the plug and it had about 3 to 5 lbs of air pressure in it. is that normal? thinking the vent line is stopped up or what. is that another level that i should be chiecking in the upper gear box on top of the axle?, sorry to be a bother and thanks for a reply. getting the truck ready for a wrecker pull to miss. bringing back another m816 for a fellow SS member to help him with his fix up Tim
