You can do the difs for about $40 a piece about $30 for the TC.

Coolant isn't bad either right? Just drain, fill, run, fill, run, fill?

Coolants not bad.... but you need to locate the bleed port otherwise you'll never get all of the air out.

On some vehicles yes. On these, no.

(though it looks like that how it is for the 3.7L... could've sworn there was a bleed port on my wifes Liberty though when i did that one, but might be wrong)

Well I need to get my ass in gear and start doing some of these things. The shop couldn't do much for me on prices, but if I go over on a weekend I'll have full access to the garage, lifts and whatever tools I'll need. Thanks for the links Sal, I'm sure they'll come in handy. And believe me, once I get the balls to try to do these things, I'll definitely be on here asking tons of questions lol.

Trust me you do not want to do it like that, I learned the hard way last week.

Whelp im going to bump this thread.
My rig is coming up on 100k here in the next few months. I have done the TC fluid change ealier this year, and diffs at about 89k. Plugs were at 80ish I think.

So that leaves the PCV valve? Whats this thing look like? where is it at on the 4.7? Can I change it myself?

Also, is there any gain from changing the oil from conventional to synthetic at 100k? I am lame and have the shop change my oil with the normal stuff, and have done so for the last 4 years. Should I switch to Synthetic?

The PCV valve on the 4.7 L is easy to swap out and yes you can do it yourself. Its located on the drivers side of the engine bay towards the fire wall on the top of the motor. Not far from the last fuel injector and spark plug. Once you pick up the new PCV valve from the store you will see exactly what it looks like and have no problem locating it on the engine. It does take a huge wrench though to get the old one off and the new one on. I bought a wrench specifically for the PVC valve and cut it down with my angle grinder so I can get in there with it. Its sort of in a tight spot.
