Jim Y.

Hello, I got a few questions about the 30,000 mile service. I have a
2004 Grand Cherokee Laredo, 4.0 liter w/Selectrac (part time and full
time 4x4). It was purchased in early 2003 though.

I'm at 28,000 miles now and have 2 Jeep dealers nearby. Their service on
most items is the same: oil change, change trans fluid/filter (not
flush), check belts, hoses, PCV valve....check coolant and flush if
needed, rotate tires, emissions, etc.

One big differerence is this:

Dealer #1 charges $479, but also replaces the spark plugs and "inspects
basic idle and set engine controls to factory specifications".

Dealer #2 charges $359 and does NOT replace spark plugs but includes
"perform throttle body-fuel inductions service".. What is that? Sounds
like cleaning the injectors (?)

My basic question is this: Do you recommend changing the plugs at 30,000
miles? I'm quite sure I don't have platinum plugs and I don't think I've
ever replaced plugs at 30,000 miles. The vehicle runs great and I want
to maintain it though.

Also I plan to request a transmission FLUSH, even if I have to pay more.
(I've done this on all my vehicles) Also, should I request 4x4/transfer
case service too? This is listed as a seperate stand-alone service and
charge. What does the 4x4 service get you?

Thanks!

Jim

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?
