I have a 2 month old AGR steering box. The 4 bolts on the top cover loosened up and did so quick in about a day. I lost all my fluid in one shot, no power steering and no brakes (I have hydroboost). I tightened all 4 bolts up and everything seemed good. I decided to give AGR a call since it really seemed odd that the bolts would loosen up like that ... and i didn't want to experiece this again! It turned out AGR got a batch of bolts with the incorrect pitch in the threads which caused them to loosen like that. About 50 boxes went out before they noticed it. They are sending me new bolts. Just a heads up. If you have a fairly new AGR box and your cover bolts loosen, give them a call and they'll send you new ones. Eric M.
