    Howdy, the other night I was trying to get under a trailer ( it was 0nly 17,000#), I got the 5th wheel under the trailer but not much farther, all it would do is slide the trailer back in the snow, I tried to get out from under it and went forward just a bit, then went back again just making the trailer slide back more, so I tried once more to get out from under and after I put it in first and let out the clutch the driveshaft broke.

    Will the driveshaft breaking like that do damage to the transmission? And do companies typically come down hard on drivers who break a driveshaft. I have 2 witnesses that were there who couldn't believe it broke due to how I was hardly on it to try and get unstuck.

    Also, this truck was in a major wreck before, the body and much of the interior is new, but everything else is original....thanks for any replies.

    Generally, when the drive shaft breaks, it doesn't do any damage to the trans or rear end. The drive shaft is, by design, the weakest link in the drive train for that reason. I don't know of anybody who got in trouble for breaking one drive shaft, including me. Just learn from what happened, and be more careful in the future. It sounds like what happened was the wheels were spinning, and suddenly found some grip, snapping it.
    Hope this helps.

    ^ His assessment seems pretty accurate. Plus it's possible that the driveshaft was already damaged from the major accident it was in... usually you'd want to magnaflux these things to determine if any fractures formed after the incident, but a lot of time that won't be done unless the repairs after an accident are already being done to components of the drivetrain. A drive shaft sees a good amount of stress as is, and a major accident can put it in a situation where the stress is increased exponentially. If you did anything, it was final just the final straw of a process which had already begun, and the end result was likely bound to happen. So long as you don't have a history of needing repairs done to your truck of the sort most commonly attributed to abusive driving, you should be alright.

    if ur company throws a huge fit and fires u for that then they r not a good company and they r doin u a favor. i drove for a guy who had me in an old junky gmc general dump truck with a gutless 300 hp cummins. it was a gallon and a half low on oil and he got pissed and fired me...i wound up gettin a better job. so dont sweat it...there r allot of companies needing drivers.

    thanks for the replies......the mechanic that towed it kinda put the doubt in my mind about how the company would react......and even if they don't boot me, they are not a good fit for me and I want to leave anyways....just want it to be on my terms...again thanks for the replies

    just an update.......they informed me my truck was done and there wasn't any questions asked by them....my only issue now is waiting for dispatch to figure out how they are going to get me back to Ohio to my truck ( I'm in Wisconsin ).......probably the way I got home, another driver coming through and headed that way...again thanks for the replies...be safe out there everyone and happy new year

    They may just be being nice, til you turn in your paperwork....

    You're not out of the woods til you get a new load dispatched.

    Hoping things work out for you....

    Any chance your brakes locked from going backward/forward while cold? Wheels would not slip but torque load could be large?
