Questions on 30,000 mile service

Jim Y. did pass the time by typing:

It's not that big of a difference. More like one wants all your money and a reach-around and the other just wants all your money.

Useless overpriced service at just 30,000 unless your tranny got contaminated with water. That and there are cheaper places to get it done.

My 30,000 mile sevice consisted of the things I do anyway.

1) oil 2) filters (air, oil, and fuel) although your fuel filter is in the tank and doesn't need replacement unless it gets stopped with bad fuel. 3) xfr case fluid (two bolts, 4min job) 4) tire rotation 5) check the coolant, belts, hoses, etc.

That's about it. Save your money, buy the service manual and get your hands a bit dirty.

Here is a clue. I have over 120,000 miles, half under a blower, and the tranny has only had it's fluid changed three times. The diffs, once. The xfr case about five times (simply because it's easy to do) and oil every 3000-5000 miles with a fresh filter.

Most of the dealer suggested stuff is pure ripoff. They would have you believe your vehilce will fall apart without spending big bucks every year or so.

Huge rip-off. Plugs shouldn't have to be changed at 30K miles.

And "set engine controls to factory specifications" simply means he disconnects the battery for about 5 minutes to reset the ECM parameters. All this does is makes the ECM "forget" what it "learned" about your driving habits and resets to default factory mode, after which it will "relearn" after about 50 miles of driving. What's he charge for that? $49.95?

Slimeball.

A $6 bottle of fuel injector cleaner in the fuel tank. He might actually open the hood a spritz the throttle body with some cleaner, but probably not. What's the charge for this service? $39.95?

Again, slimeball.

I think the 30K service is oil, suspension lub, aircleaner,plugs and possibly t/f case fluid

Thanks to everyone for the replies.

On most of my other vehicles (non Jeeps) I've not adhered to the maintenance schedule as closely.... tranny usually at 45,000 miles.

But, several Jeep owners I know-- some who have had numerous Jeeps, have said, by experience, that they avoided costly repairs by going by the maintenance schedules---- especially with the transmission and differential fluids.

I was trying to get a feel if these vehicles are a little more "high maintenance" than other cars/trucks.

I normally change mine at 50K.

Matt Macchiarolo did pass the time by typing:

I replace plugs every year (10,000 miles) basically because they are cheap and it's easy to tell any internal problems by looking at the plugs.

Nothing's missing now. My Ford van called for new plugs at 75K miles. Technology has come a long way since 1953.

Only has about 37,000 miles on it anyway. Runs like a champ. It doesn't have mechanical fuel injection, the fuel cuts off when there is no power to the injectors. Like I said, we've come a long way since the 1950's, Bill.

Jim Y. proclaimed:

Spark plug replacement is in the FSM at 30K. So is drain/refill transmission and transfer case. And check the serpentine, which is pretty cheap to replace rather than mess with.

Pick up a Factory Service Manual from

Great investment.

Uh Bill, is that a "Real" Jeep wave you're giving us there?

Yep, I suppose the ECM is flashed to misfire at 30k just to remind you to change the plugs.

No decrease in gas mileage, and yes, I will change them soon. If you want, I can fly you up here and you can change them for me...it's been unseasonably warm here last few days...today we nearly got up to 30F. Thursday it was 6F. :-)
