I'm resurrecting a very old post, but I just hit the 30k mile mark in my Liberty. The CD manual I was given states to do the following at 30k miles:
Inspect the transfer case fluid.
Adjust the parking brake.
Replace the air filter.
Replace the spark plugs.
Every 18k miles "Inspect the front and rear axle fluid, change if using your vehicle for police, taxi, fleet, off-road or frequent trailer towing."
So, if this is my DD and not abused for fleet service, do I not have to change these fluids? I've off-roaded maybe 5 times since purchase and pulled a trailer twice. But, my Jeep was a purchased used and was a rental prior to me owning it. Knowing how people treat rentals, should I have everything done now just in case?
Is there a dealer anywhere that would 'inspect' these items and not suggest full service???
Being a rental, qualifies that as fleet use, so it should have all services done by severe service schedules up until the time you bought it. You're at 30k, so plugs are automatic, if the air filter is dirty then replace it, if not, dont worry with it. I would go ahead and change the gear box fluids, since it was a fleet vehicle, and knowing fleet maint., it was never done.
