2024 Freightliner DT12 output shaft covered under warranty?

It was a used fleet truck. It had the extra warranty for 600,000 miles part and labor was included. Not sure what happened to the engine before I got it. I guess a bad build from Detroit Diesel. I had the repair record from the fleet they did not show any major engine repairs. Head gasket was leaking oil. When they got the head off. They found all kinds of problems. Freightliner was telling me I might get a new engine. They sent pictures and everything to Detroit Diesel they said to repair the engine. I didn’t like freightliner doing that much engine work but it was all under warranty. I was thinking they will find a way to void the warranty. Detroit said take engines to the block. Who know exactly how much the did. They had to replace a piston and reset the liners. So they probably did it. They did not know what was in the coolant ports in the block but said it looked like rust. The engine had new coolant when I got if from the fleet. Detroit Diesel did all that work under warranty. Freightliner even said I was lucky it had that extra warranty that included parts and labor for 600,000 miles.

 

I wouldn't give it a second thought and I WOULD RUN THAT MOTOR like a beat up pitbull for the next 100K miles.

You got a free inframe, who cares if it costs a week or so of downtime.

Good on you for gaming that warranty. Don't idle it at all, run it.

 

Detroit Deisel has made the motors that have allowed me to pay off a house and provide me a family...

 

Believe it or not dealers typically get bent over on warranty work.

 

Clunk noise doesn’t sound good. Might be more to that yoke going bad. Seems like it should all be covered by the warranty.

 

Yoke will not going to fix the problem only if the yokes center bolt is loose. Most likely the bearing for the output shaft inside the splitter housing. Easy fix need to pull transmission and separate splitter housing from tranny. Bearing is $40-50 last time I checked. Dealer will sell you the hole splitter unit for $3000.
