Ok so Im at about 31k on my Liberty. Just before I hit the 36k mark I want to take it in to be checked out by the dealer. I bought it used so this is it, I will not have the lifetime power train.
So I want the differentials, transmission, transfer case, ball joints, etc checked out. Can you just say check all these and they will? Will they charge me for this? Or do I need to say I hear a weird noise, popping , grinding etc to make them have to check these out without charging me? What is the best way of getting the important stuff checked and fixed under warranty to ensure I have the best start when Im "on my own"?
You're due to have the diffs and t case fluids changed anyway. Ask them if the tech can also do an inspection on everything else and have the inspection documented. The powertrain has a 100k/5 year warranty, everything else is 36k/3year.
Talk specifics with the service guy and tell him exactly about wanting the drivetrain inspected in case there was abuse from the PO. If he doesn't want to elaborate on what the tech will do then find another shop as he's just a salesman. Also have him explain the difference between a trans service, and a flush. Since the don't seem to have replaceable filters these days, they tend to not drop the pan and look around/clean gunk out. Not all techs are enthusiasts and are just about quick turns, or upselling something that's not really needed.
I now see that the 5yr/100k mile powertrain does carry over, i had read the threads where the lifetime warranty that used to come with the older models does not carry over for used. Makes me feel a little bit better.
There are filters in the tranny from what I've been able to find. I spoke with the head Jeep mechanic at a dealership I used to do business with. He told me they got rid of their tranny flushing machine because it was causing problems and now they drop the pan, push out the old fluid, replace the filter and button it up.
