100k miles.. What to start watching for?

I bought my 05 jeep tj about 4 years ago. Bought with over 60k miles, and I just recently passed the 100k mark with very little going wrong. My goal is to get another 200k+ or 20 more years out of this. My question is what things should I start keeping an eye on or inspecting regularly? Iv been reading up on a ton of guides and DIY stories on things like transfer case, Auto trans gasket/ filter and flush, OPG/ RMS gasket, timing cover gasket and chain, differential fluid etc. I do have some minor "leaks" and oil blow back from the fan but nothing that leaks spots on the ground. I know if it ain't broke don't fix it but I'd like to start making a list. Are these fluid flushes and gasket swaps something I should be considering at 100k? It's my only and DD vehicle so I'm in no rush.
Iv maintained oil changes every 6months or so, went through a recent bout of DW and had the tires balanced ( thanks jerry), air filter changed, serpentine belt, brakes and various suspension and steering parts replaced, spark plugs etc.
No lift, mostly all stock components OEM and I can only assume nothing has been changed/ flushed/repaired as of yet or by PO.
What's are your thoughts?
Thanks and cheers!

If it was my TJ I would get an Original Equipment Manufacturer (OEM) Factory Service Manual (FSM) and follow the maintenance schedule, it will call out most of the required maintenance for time and mileage change requirement's.


Changing the brake fluid and power steering fluid would also be a good idea... IMO

I'd love to own a physical manual but those are anywhere from $100 to $300!! I see $5 downloadable PDFs, how can I tell if it's legit? Have any recommendations?

my '05 is at the same mileage, so far so good. maybe because I follow the "B" service schedule in the maintenance manual and do a few extras like brake fluid, manual transmission fluid etc.

the only thing I've had fail is the radiator, but have replaced a few other things that were starting to deteriorate like tie rod ends, shocks etc, but nothing that was a show stopper

managed to download an OEM manual for free years ago

Change all fluids and be done with it.

Thanks for the the link. Picked up 05 manual for free. Looks like I should start doing fluid checks/changes anyhow. I think I'm gonna do the diffs today.
I think I'm to eager to learn and get my hands dirty

Yep this. Every fluid, as mentioned above don't forget brakes, power steering, diff's, trans case.

Check all U-joins (drive shafts and front axles).

Tie rod ends in steering components, ball joints & unit bearings.

ah yes. I forgot all about that.

for 05/06 Wranglers, all the info is here http://www.jeepforum.com/forum/f9/20...ilure-1144202/
.....all 5000 plus posts.

for me I got onto it early and did the 'fogmod' and purchased a spare OPDA as it scared the bejesus outa me. the spare is still in its box unused in the shed somewhere and now a much better Dorman or Crown unit is available

other thing you may get 'emissions not ready' and a simple wiring mod fixes that especially if you get some funny O2 codes. see this http://www.jeepforum.com/forum/f9/02...d-try-1447579/

havent done it myself as annual emissions testing doesnt apply here, but I get a pesky P2098 code every now and then that I think is related to it. I just clear it and drive on.

FSM PDF downloads are out there free. Just look around. Keep doing the normal scheduled maintenance and catch trouble early with smart troubleshooting and you will be fine

Thanks all! I managed to get a fsm and one pmed for free. You guys rock!

On a side note, any idea how to keep the GF from hating my new hobby and how much time and $$ I'm putting into it?
