Hello Folks- I apologize if this is buried in a thread somewhere, but I haven't been able to locate it if one exists. Only a thread on DIY work which was certainly insightful.
As someone who likes to plan ahead, I'm rather curious to hear some of the long-time owners thoughts on Drivetrain Maintenance. I've read the owners manual twice, and haven't really come across any definitive timelines.
Seeing as the 7 speed tranny is a sealed unit, I do not plan on replacing the fluid. I don't really buy into "lifetime fluid" performance, but the manual says no regular maintenance is required, so I won't be doing anything. And yes, I do know a few folks whose sealed transmissions have crapped out after being serviced. I guess as with most things, experience can be our biggest influence.
For the differentials and transfer case, all I can find is for them to be inspected periodically. The local dealer has a schedule of 30k miles for the rear diff and transfer case, and 60k miles for the front diff. Does that sound reasonable to those that have owned these cars for a decent amount of time?
I know some dealers like to pad their profit margins by performing sometimes unnecessary maintenance, but I don't want to neglect anything either since certain repairs on these vehicles can get quite pricey. But I can also state that while growing up, my father never replaced the fluid in either of our Jeep Cherokees' Transfer cases, and they worked flawlessly until they were finally dumped due to advanced age and overall wear.
Thanks in advance!
