Broken front drive shaft

Not sure what caused it to break but my front driveshaft split in half. I had it in 4wd and was doing a K turn to back in my driveway in a snow storm.

I got underneath in the snow (miserable) and wasn't able to come close to getting it off. The bolts holding the shaft onto the t-case will not budge and the tiny 5/16" bolts stripped all my small 1/4" sockets. I'm guessing I need a 3/8" drive 5/16" for front and the rear just spins. Any tricks to getting this off the truck.

Thanks
Matt

My suggestion is to use an impact if you have one. Those little guys are torqued to 82 ft-lbs, and you'll break just about anything 1/4" drive trying to remove them.

I'm guessing you had some bound up U-joints that caused the shaft to fail. Can you post some pics?

Try some PB Blaster on the bolts as well. That may help.

If there was red Loctite thread locker used, you are going to need heat from a torch...

Dropped it off at my buddies. He has compressor setup.

I'll get some pics when I get it out.

Thanks

Wow. What as the condition of the U-joints? Do they still move normally?

I agree. That is pretty bad corrosion. Good thing it didn't let go at speed.

Picked up the new drive shaft. Thing is solid. The guy said he did about 20 of them in the last week and was on the phone with another broken one while I was there. Here are some Pictures. Of course it's snowing now so I can't get it in.

Looks nice!

Driveshafts aren't too bad most of the time. Had a steel shaft fabricated for my Lincoln last year and paid $300 for it. Much cheaper than lots of other stuff that can break on these things!

I thought only Chevys broke drive shafts. That's what was presented on Top Gun BBC Monday Night

Seriously, it sucks your shaft broke but you were able to get it fixed. Also good info to know in case I ever run into it out in the wild. Knocking on wood I won't.
