How could this happen? And how much to fix? Torn out glad hands

Either one of the air lines or light cord came loose and wrapped around the driveshaft or dropped onto the road and the left front tandem wheels ran over it and yanked it all out. So you will need the air lines and light cord, maybe a tractor protection valve. The 2 holes next to the cord socket, the ends might be able to be removed with an extractor and new air lines attached if the valve is not cracked, broken or threads damaged.

 

And it is your fault

 

The gear that suspends the air lines/electrical, often from a crossbar on the back of the sleeper, may have broken and that allowed one or more of the lines to fall onto the road or get tangled around the drive shaft. I've had the little spring clip that connects to the spring break a couple of times over the years. That's my guess.

 

If they got wrapped around the driveshaft, there should be visible evidence of where they whipped the piss out of the frame rails. Most likely got under a drive tire and flew out the back like a snake that hit a live wire….

 

I wrapped some around the driveshaft on a similar Shaker. The pogo stick was broke. Everybody else drives it like this so it will be OK right? WRONG! It took awhile to get all that junk off the yoke. It also pulled all that stuff off the cab. You are lucky there is not more damage.

 

About $250

 

This ^^^^^^^
At least 250 probably cloeser to 400
And Yes it’s your fault

 

Called "#### happens"

 

What's the other two electrical sockets on the back sleeper wall for.
