Don't know if any of the fluids have been changed by PO. What would you do?
Thanks!

Well, I remember someone saying its not good to change some fluids if you have high miles and don't know if they have been changed because it could cause more damage than leaving them in.

Just don't FLUSH them. Your seals and synchros and chains and teeth have become best friends with the deposits left behind by our old fluids. If you flush the deposits out, the components get separation anxiety and get very, very angry.

I would do this...
Change motor oil
drain trans fluid and refill
drain tcase and refill
change diff fluid front and rear
drain antifreeze and refill
drain power steering and refill
change brake fluid
That should cover all the fluids..Like trueblue said just don't have the tranny and cooling system flushed..

Drain it run some water through to clean any rust out then refill with fresh..it'll cool the engine better..The question is when was the last time the PO changed it never more then likely..
Also if it's a used car I would also do a complete tuneup...cap,rotor, plugs, wires, air filter, fuel filter...
These are things I do anytime I buy a used car..

Well if you flush a radiator and cooling system that's never been flushed could cause leaks and so on..Me I just drain the radiator then grab the garden hose and run water through the block in case any rust is settled in their..A trany flush could cause goop to loosen in places you don't want it to...

i work at a jeep dealership and i personally dont think it matters with the aw4. that is such a tough trans. We have had guys at are work flush their trans with a 150000 and to his knowledge never had a flush and it actually made his shifts alot crisper.
