How is that for overkill??
Do you have a reference for that because I simply do not believe that. That cannot be true from the manufacturer. Dealership may push that but it is NOT required to do 15,000 mile diff changes to maintain your warranty.
Yep, my 05 Liberty specs the same thing in the manual. I'll post a pi8c if you have to see it to believe it, but it's true. Whether they actually care if you do, probably depends on the dealer but it's for sure in the manual. I do mine every 20-30k with dino 85w140.
Wow, I looked it up and you are correctit's actually every 20k miles - that's just crazy! I've had several Jeeps and never that small interval. Wonder why? Seems like diffs are the one part many people never change and they go on forever with minimal maintenance. Me personally, I do all my diffs at 50k intervals and transmissions and transfer cases at 30k miles.
Thanks for sharing!
They must have changed it, my Jeep manual doesn't mention differential service, just transfer case at 120k.
