GEM computer fouls up, send signal to electric motor saying "4 wheel low please", at 50 mph and boom. Fortunately everyone's OK, and you're not in for a tranny or worse. Cop friend of mine swears that when it happened to him the radar gun on the dash broke the windshield. In lawsuits we call it "sudden drivetrain lockup"

thats why i got a manual trans shifter and manual hubs no surprises. sorry for your bad luck seems like it is always something breaking for me as well. i think if you see can light at the end of the tunnel , its a freight train baring down on your a** !! happy parts hunting.

 

Does it matter which NP 273 I get? Found some online but cannot compare part numbers because mine blew off the transfercase. Found some online for $366 shipped.

 

Here is a link to the site where I found the T-Cases for sale. Not sure if anybody has ever tried from here but the price looks good.

And that has what to do with a police officer showing up in court? They are required to attend court.

 

and this has what to do with this thread?

you must be a cop.........

 

Okay guys, finally got this whole thing fixed and taken care of. Sorry for the long delay in getting back on this one. Here is the update:

Found the initial problem: The double cardon on the front drive shaft suffered a catastrophic malfuntion where the sleve in the inner joint failed. This of course caused a death wobble and eventual explosion of the transfer case.

Transfer case: Found an awesome place in Lancaster called Autofox Recyclers. I picked up one with <50K miles for $375 with the electric motor!!!!

Brought the front driveshaft to another place in Lancaster called Yarmin Driveshaft. This place does great work but they have the WORST customer service. I went there on a recommendation and I DO NOT recommend this place to anybody else. It took them a month to get the driveshaft back to me. Hence the late post.

Oh and while I was at it, I replaced all of the U-Joints. I didn't replace the bearing though. I know, but hey after all of this I was kind of straped for cash.

So there it is. The ending to a catastrophic event. Its back up and running strong.

Later Guys!!

 

Thanks for posting your resolution to the problem. It's great for others who might end up in the same position. Had a Jeep Cherokee that did the same but only cracked the casing. Blamed it on using 4-low to drag a baseball field and making too many tight corners. When it died, my son was driving home from school and had it in 2-high also. Reps for posting back.

 

Same thing happened to me. I was driving down the highway and BOOM! How much am I looking at to fix this?


Same thing as he described!

 

Same thing happened to me! Driving down the highway yesterday and BOOM!

 

Holy crap! That is shor nuff ugly. We're your hubs locked or were you in 4WD?

I've seen them going for 400-500 around here on Craig's list. Hope no one got hurt and maybe you can get the stain out of your seat.

Here is one I found locally.

 

Hahaha. Thanks. No. Just driving along. Not in 4-wheel and not locked wheels.

 

I've only seen them blow in trucks that were sled-pulling or doing boosted 4wd launches while drag racing. They're pretty stout units. You should Be impressed with your ability to break one

 

so in my opinion if it had been engaged at speeds the bolts that hold the drive line to the t case may have backed out allowing play which would explain the rough feeling followed by the drive line flying loose and causing the t case to explode did you have the front drive line off recently?if the thing has vacume lock hubs malfunctioning they could be engaged even if it's not in 4wd so your 4wd light will be off your hubs will be disengaged and the front drive line will not turn free even though is "should be" disengaged
