c15 went bang

Well last night on my way back from Iowa i was about 20 miles from the MN border on I35 when all of a sudden the truck went bang. Then i heard what sounded like the driveshaft spinning on the ground. I thought i blew a u joint, but when i pulled over the noise continued. I shut her down, got out on the pass side and saw oil running down the shoulder of i35. If anyone was up here you know it was about -10 last night and i sat there waiting for a tow for 4 hrs. I thought i threw a rod, but after further investigation the oil was coming out of the trans inspection plate. So it must be leaking out of the rear main. I am wondering if the crank snapped off? I am waiting to hear from CAT as to what they found. This is in a 07 379 (ex TMC truck) with 378k on it. No warnings of any kind, she just went boom. Also the esc plus coverage expires on 12-21-2010. So couldn't have happened at a better time.

 

Yeah it did. I too also hope that what ever it is will be covered. It has the esp plus so its the top of the line warranty, but like you said hopefully they don't try to get around it.

 

no, i don't believe it did. I can't say i remember too much as it happened so fast. The whole truck was shaking really bad though.

 

Ok, CAT just called me. So far the clutch grenaded, but they haven't dug into it far enough to see where the oil is coming from. They said it could be anything from the trans to the crank.
