hey guys, i noticed some extra movement on the front wheel of my truck. the truck is a 93 w-250 with the 4500 lbs front dana 60. i think that the nuts may have backed off a little bit. i did the bearings about a year ago and believe that they are in good shape. my question is. . is there a little keeper pin that holds the nuts in place? so they dont back off? i was also wondering if anyone has any pictures or drawings of how everything is supposed to go? i looked in my FSM and there isnt a expanded view of the hub/bearing assembly. also i cant find anything on the internet.
