While driving to boston yesturday, my truck felt as if i had a flat, i stopped, looked at the tires and such, no problems? then i noticed 4 of 5 wheel studs were sheared off at the base. my tire was held on by one lug nut. eeks got it towed, (also sheared an inner nut .) any one have any ideas as to why ? the truck had manual hubs put on before last winter. other than that no other work or problems with the front end.
My .02 Sounds like the lugnuts loosened up. Happened to my old Dodge P/U. Had a set of tires put on it, and they did not tighten the lugnuts properly. They only difference is that my tire did come off. Sheared all 5 lugs off. Tire went fluing and broke the front axle u-joint. Did you or someone else change out the lockouts? Did you take the wheel off to change the lock outs? If so, sounds like the lugnuts didn't get re-torqued when they needed to be. Mine fell off with in 300 miles of the new tires. Just my thoughts. Glad to hear you didn't get hurt or anybody else for that matter.
I have had it happen twice on a Ford 1 ton truck that I used to drive. Both times is was my left hand side with those left hand threads on the wheel studs. It would shear all 8 bolts usually before I realized what was happening. The last time I was loaded with 8,000 lbs of fertilizer, but going pretty slow. I would say you had loose lugs.
Wow. My friend's mom had a tire come off while she was flying down the highway once. I'd probably do something to my pants if that happend to me.
I had that happen to me one time when I was driving Greg's 68 Dodge Polara that he and I had built. Scary thing is that just before that I was flying down the highway about 90MPH!! I was about 3 blocks from leaving town and heading down that same highway to go back home. Lucky me. That would have hurt a little if that would have happened at 90!!
NOT FUN. Sheared L.F. spindle on a car JUST AFTER Bonzi run with 2 passengers, "to see how FAST we could go" in an old clunker. Had to make a stop, and JUST started the left turn, when the LR wheel assembly just dropped! At 16 didn't realize HOW LUCKY we really were. I HAVE heard of this happening on 3 91 Dodge trucks recently, all were used in HARD fleet service, all 4x4s, 1 2500 extended cab, 2 Dakota ext. cab. and it also happened on a 96 1500 Dodge in the same configuration Dakotas had the Factory "Mag" wheels, the big trucks, had the steel rims. There MAY be more to it than just loosening of the Lugs. You didn't say what type of truck you were driving, but w/5 lugs, I think it was a 2x4. JR
