Broke down !

Doesn't sound like anything you did and yes I am broke down too. Truck shut off coming into Oklahoma city.

 

Broke off like unhooked? Probably a broken U-Joint id assume. Not your fault. Inspection should have shown a bad joint so it could have been fixed but they do go out and sometimes if youre lucky, you get to watch it fly across all the lanes on the highway..

You should be back on the road quickly. Good luck!

 

Sounds like the universal joint broke. They fail over time. You should have felt some vibrations for a while beforehand. One of the things that should be done on a pretrip is check them for play. As that would require crawling under the truck I usually only do it about once a week. If you grab your drive shaft and have "play" in it then the universal is usually bad and should be replaced asap.

Nothing major. Happens all the time.

 

Pinion. umm... Not so good..... I couldnt explain that. For it to come off there would have to be some definite broken parts or someone took the nut off that holds it on and it came apart... And those things are set pretty dang tight, unless someone worked on it recently and didnt put it together right.

 

It's probably somewhere on the side of the road. The shop will have parts.
