I heard some noise heading up to Shawnee Peak to do some skiing. I felt a fibration from the wheel and it almost sounded like the wheelbearing went to hell, if i turned to the left the front end grinded and felt terrible. I told my girlfreind that it didnt feel safe and that we should not be driving it. I got out and checked the lug nuts and also looked at everything underneath the truck, everything looked fine. Only one stud from the right front broke off flush.hmm. I have the steel stamped rims that came with the truck (170,000miles). Anyway about 1week of grinding later i was traveling down Rt 202 in green maine at night at 55mph and the wheel went past us!! my supervisor from work looked out his window and said "Now that cant be good." at the shower of sparks. It looked as if we were entering the atmosphere. I gingerly applied the brake and slowly brought the truck to the side of the road. phew. I walked back and got the wheel..after inspection it appeared the bolt holes were elongated, the lug nuts were still on the studs and all the studs turned so i could not get the lugs off.hmm. I hope this dosent happen again. has anyone ever heard of this happening?
