Shouldnt the rear end be vented where the bolt holds down the flex hose on the diff?
im not sure i understand what this means.
this is the stock setup as far as i know, doesnt look like anyone has changed anything down there. its a 7 1/4" rear end...if that makes a difference?


edit: looks like the other rear ends have the vent bolt there, but the 7.25 has a different one elsewhere?
