dana axle/gears

first off forgive me i am not a mechanic. i own a 2009 international prostar. it has less than 250,000 miles on it and a 5 year or 750000 miles warranty on the drive train. i do household moves and haul light compared to an 80000 lbs hauler usually always less than 70000. i was driving recently with a light load in town and took off at a stop light. thats when a metal grinding noise started to occur. i thought i dropped an axle. although i was able to keep driving and it begin to go away. so i thought it was stop gearing issue. took it to international and the problem was an inter axle gear problem i guess. the collar was broken for the cross shaft. because the collar was broken they say driver error and will not honor warranty. the came up with a scenario that my wheels were spinning and caught solid ground all of a sudden. they put it under this category to deny the warranty. these were not my driving conditions and this did not happen. i am trying to educate myself now and see how this happened. i do not want to pay for this and feel dana should honor the warranty. can anyone help?

 

thankyou and yes i am doing exactly what you stated. i am having them send me the pictures they sent dana. i will be going up there to take my own pictures. i found some sites that explain and show wear patterns. vin 9c122579.

 

again i am educating myself as i go along. i went up to international and took this picture. i looked at all the components that had teeth. none of them were broken and showed signs of harsh wear. lubrication was good. again when the collar broken i was driving without the power divider engaged. i was pulling out of a stop light wheels were not spinning. i realize this could have happened over time but there doesnt seem to be wear of the other components or broken teeth. i dont get it. any thoughts? we are dealing with torque and momentum hell everything is shock load really.

 

thanks for your time on this matter. i will be calling the 800 number tomorrow. the pictures were sent in and dana denied warrant-shockload failure. does a 5 year 750000 mile warranty really exist dana has a webpage that shows many pictures of wear and tear to drivetrain components. pitting, teeth broken off, heat damage(lack of lubrication) ect... the definition of shock failure on the dana web page states shockload failure- violent impact on a tooth that usually causes the tooth to break. based on the picture the teeth are not broken on the collar the collar itself is broken. do i have a technicalitly case-i will try. also the collar looked to be the only component damage. with the collar broken like that wouldnt that have caused the input shaft to twist even a little or for some other components to be damaged before something like the collar to just break on its on. the definition of a cluth collar on danas page states clutch collar-device used to engage from one gear to another. if they(dana) stated that my wheels were spinning then caught solid ground how does the clutch collar come into play. if your wheels are spinning how can you shifts gears?

 

thanks bender. a lot of the situations i have heard have been from wheels spinning and engaged power divider. it is frustrating because i havent done this with my tractor. what i was taught early on about locking axles has always made me hesitant to do so. i understand the damage that can be done if engaged and use improperly. so to know there is another way to break the collar without having to engage the power divider makes me think a little more. there are times locally when i get weights for a move and head back out to deliver the furniture where i get on the scale and brake maybe 95 percent stopped and throw on my parking before completely stopped. i think that is possible.not saying it happens a lot, but it is possible. even though it feels i have almost stopped there is still some momentum that has not finished stopping.is that enough to break the collar over time without any wear to the other components? i havent had this problem in my '99 9200 international. with nearly 1 million miles. just seems these problems should not occur 230,000 miles into driving for a tractor i paid for. just curious has anyone been or heard of someone being covered by warranty for a broken collar. is it an automatic denial that is assumed to be shock failure.
