Hi all,


While I was under my Commander working on replacing my oxygen sensors, I noticed grease leaking around the seal that connects the front drive shaft to the transfer case. After wiping up the grease, sure enough there is a small tear in the boot.



1. Would this be the Input Shaft Seal - Mopar (5143714AA)?
2. Any chance its covered by the lime time power train warranty?


Thanks

If it was grease (not transmission fluid) then it is coming from the front CV joint on that driveshaft.

It's definitely grease but its not the front of the driveshaft. I can actually feel a small tear in the rubber right before it enters the transfer case.

Let me clarify, the QT-1 transfer case (NV140) uses ATF+4 (transmission fluid). So if it is the transfer case shaft seal that is leaking, 5143714AA is the correct part.

I found someone else had posted the same thing on this forum back in 2009. https://www.jeepcommander.com/forums/9-problems-dealer-service/11144-vibration-noise-while-accelerating-front-propeller-shaft-leaking.html.


From what he said, he had to have the whole driveshaft replaced as they dont just have a separate seal. Its not ATF but black grease. The attached picture is from his post but identical problem.

I'd say the lifetime drivetrain warranty should cover it, talk to the dealer. I had the front Diff bushings and water pump covered under the warranty. It covers a lot of things.

The CV joint boot on my front driveshaft went bad awhile ago (transfer case side) and I rebuilt it with this kit. https://www.amazon.com/APDTY-Propeller-Drive-Shaft-Transfer-Case-Mitsubishi/dp/B00C8EAK38/ref=sr_1_7?crid=WQFQIMR6PWTZ&keywords=jeep+commander+cv+joint+kit&qid=1559936468&s=gateway&sprefix=jeep+commander+CV,aps,247&sr=8-7 The most difficult part was getting the driveshaft off the jeep.

Okay thanks. After going back and forth about it I now realize that is it part of the driveshaft before it enters the transfer case.

I certainly hope so. It covered my water pump as well. Is there documentation on what exactly is covered anywhere. I'll have to look through my owner's manual and related paperwork.


I found what is covered:

Speaking of life time warrenty, how do I know if mine is still covered? Is this for original owner only?
If you are not the original owner, you're not covered by the lifetime warranty; You can read more about it here;

https://www.jeepcommander.com/forums/23-regular-service-maintenance/74549-lifetime-powertrain-warranty.html

I've only heard of one member who apparently bought his XK from a dealership a number of years ago, where he was apparently given the opportunity to purchase a Chrysler lifetime warranty;
