Suggestions wanted for 100K preventative maintenance

[philswatch]

I've got a 2002 XLT with a 4.6 modular. 100K miles. All is running fine right now (knock on cheap particle board desk).

No history of issues. Since new, I have done a fuel filter, battery, brake pads... and that's about it. It's driven by light-footed wife and daughter. Never towed anything. Allot of highway miles also.

On a intermittent basis, we have that delay going from Park to Reverse; it's a minor problem I think I'll ignore. I don't want to go poking around the tranny for such a small-beans issue. That would be inviting fate.

To the question: I was thinking of taking it into the dealer (I have a good honest, not too expensive one) for some preventative maintenance. What should I have a dealer do (and not do).

Is it worth replacing the timing chain?
Replace fuel filter?
Other?

On the other hand... maybe all I should do is keep changing the oil, and stay out of the shop until there is a problem. That plan has worked well so far.

I just did the same to mine. I replaced:

-Plugs/wires
-Idler pulleys
-Tension pulleys
-Belt
-Front and rear diff fluid
-Engine oil
-PCV Valve
-Fuel filter

What you can do:
-Transmission fluid
-Transfer case fluid
-Power steering fluid
-flush radiator

Thats about all I have. I've maintained mine well over the years so I didn't have much to do since I'm nearing the 100k mark.

fuel filter
air filter
front and rear diff fluid
t-case oil
serpentine belt
oil change
plugs/wires
fuel injector cleaning might not be a bad idea.

Don't think twice about the serpintine belt and pulley.

I have about the same mileage but I do the tranny fluid every 12k b/c these trucks are known to blow them due to a steel pin in an aluminum shaft or some other careless engineering.

Anyway, I would do the tranny fluid. Skip the T belt or ask your guy.

We had to do 3 wheel bearings for about 700 bucks total, otherwise a good truck for us.

my 92 has that annoying delay when it goes into reverse, but i just let it go, no biggie.

Thanks guys. I'll bring it to the shop soon --- before that inflation comes in that will have us bring wheel barrels of cash to make even small purchases.

If you have never had your fluid and filter changed in the transmission you probably want to do that.

High $$ end preventive maintenance:

- Transmission and Transfer case pan drop / fluid + filter change
- Drivebelt + tesioners
- Front + Rear diff fluid
- Engine oil + brake fluid + hydraulic fluid change
- Air + oil + fuel filter
- Spark plugs + wires
- Check brake pads and rotors

Low $ end preventive maintenance:

- Transmission + transfer case fluid change
- Drivebelt
- Front + rear diff fluid
- Engine oil + Air / oil filter
- Spark plugs
- Check brake pads and rotors
- Go to church and pray.
