I got my truck back for the third time back at the body shop for adjustments. Needless to say this whole wreckin my truck thing has been on BIG CLUSTER#$@K!!! So this time I get it back and Im getting a heavy rattle coming from the driverside rear of the bed. I go under and look and a hose what looks to be a breather or return line coming from my driverside axle housing where its screwed in and the other side is just dangling and rockin up against my shock. The otehr side has a vacuum line type fitting on it I was just wondering where that side connects at??? I dont wanna go to the body shop again and loose my truck for 3 days while retards try and fix it but I dont have any access to rack so I cant get all the way in there to see any connection point. I checked the underside and both sides of the diff but cant find its home. SOMEONE PLEASE HELP ME IM ABOUT TO JUMP OFF HOOVER DAM!!!
