Started the year off right, went for a drive in the bronco
right?... and well, had me a close call, turned off the highway and noticed something wrong *bumpabumpabumpabump* WTF?! felt like my rear end was binding when I went around the corner. Pulled into the parking lot where I was going anyway and *WHAMN* scisssssh... Tire falls off and I skid to a halt halfway into a parking stall. W. T. F!.
drivers side front. Chewed up the holes on my rims, scrached my wheel cylender from the pressed in studs kicking back into the drum/pulling out of the mounting plate, busted the pressed on drum loose from the hub, and (I think) warping the drum (It now skuffs, and gets louder when I turn) Borrowed some tools from the auto parts, bought some lug nuts, and with the help of some nice people, was able to limp home (even though I forgot to get the item I came into town for!).
I know that last time I did anything with the rims I tighened everything down with a lug wrench good an tight, and 3 miles before this I had glanced at the rim when I made a stop and didn't notice any nuts missing (I am running new aluminum rims with 31 inch tires and chrome acorn nuts).
I went through and rechecked all the other rims when I put broke out the lug wrench to fix the one that fell off, and found a couple sprinkled through the other 15 lugs that took a 1/4 turn, give or take (nothing eye openingly loose or anything, the rest had at least 100ft lbs trq on them)
but I had 4 or at least 3 lugs fall off by themselves in just a few miles on ONE wheel (drivers side front) only and then had one stud torn out of the hub and another knocked loose.
I had an issue with this hub before of loose lug nuts, I thought that it was just a fluke that I had forgotton to fully trq the bolts after spinning them on with the lug wrench, but am now wondering if there is an underlying issue on this hub.
When I took this drum off today I noticed that the inner wall of the drum had rub marks on the wall as if the shoes were too wide. Perhaps this is creating a vibration that rattles the nuts loose? I have no idea
this is a 1968 U15 with a dana 30 front axle with 11 inch inner diamiter brake drums. drum surface is 2.03 wide and the shoes are like 2.01 wide
But this is very concerning to me, there was a very real chance of a rollover or some other serious accident here, I can't put this back on the road if the lug nuts are going to keep backing off!
