So there's your problem!

So I blew the U-joint in my front shaft at the trasfercase. My TnT belly skid came in handy since the shaft just fell on it, and I was able to drive home without disconnecting it at the axle. However I was unable to shift the case into 2HI from inside the truck. I drove home and parked it for a few days until I had a little while to look at. I took the front shaft down today and realized why my case wouldnt shift into 2HI.

I figure the when the u-joint broke it threw the shaft at the linkage. Bummer.

Nothing a BFH can't fix. :D

Consider yourself lucky. Second last time I broke a drive shaft (and last time I broke a front drive shaft) was in a full time 4wd K10. More than 1000 miles from home in the US on Saturday July 4th. Nobody was open.

 

By the time I had coasted to a safe pull-off, which was a bit because I was on a bridge when it happened, the front half had punched beat the oil pan to a pulp, although it was not leaking, and the rear half had punched a bunch of holes in the transmission pan.

 

I stole a transmission pan off a used truck at a dealership, leaving my name and phone number both under the wind shield wiper and on the showroom door. Then I couldn't get the transfer case into 4 lock, so I ended up wrapping a chain around the frame and bolting it to the front output flange of the transfer case. That got me halfway home when I found a drive shaft shop sign on an old barn beside a house. Rang the doorbell and had me two custom 1 ton drive shafts made, one for the front and one for the bent rear one (Yippee! No more vibes). Also found out the reason it wouldn't go into high or low lock was too much clay built up on the linkage. Gotta love northern Ontario clay.

 

Monday at home I got a call from the dealership telling me not to worry about the pan as that truck is going to the scrap yard anyway. This was back in the 80s.

 

Second drive shaft I broke was anticlimactic. I pulled an F550 dump truck away from a stop sign and made it 2 feet before I lost power. Drive shaft broke at the rear u-joint and fell to the pavement. That was in 93 or 94.

I twisted a drive shaft in two in my CJ7 trying to pop the front wheels off the ground having 35" swampers... :shake: I know, I know.. I was only 17... It made the biggest pop and started to beat the hell out of the bottom of the floor.. It scared the all living jeepers out of me.. I thought I'd $#!& meself!! Thankfully I was only 200 ft from the house, I pulled the yoke out of the transfer case, and crept it on home in 4wd. I was lucky it broke near the rear end. The small piece was too short to hit anything, so it just flopped around till I got home. I'd thought I'd died that day.. Never tried that again.. Good thing about making wrong decisions is you know better not, next time!
