hey guys i have an 05 rubicon (6 speed manual) that i got with 10k miles. i have changed the oil 3 times already and it has 17k on it right now. im trying to maintain it the best i can. i live in cental texas where its really hot we do triple digits almost everyday of summer. winters arent usually bad we have a freeze everyonce in a while. my question is besides changing my oil every 3k miles what are the other things i need to do, such as radiator flushes or coolant changes, tranny fluid changses, differentials, greasing all the little certs that are under the jeep. could somebody let me know so i keep this jeep running forever.  

Your owner's manual has all the info. Even has a place to record the dates when the service was done.

Use synthetic in the diffs and TC and change them every couple of years unless you're in the water deeper than your axles. Then change them when you get home.

The coolant is a five year, 100,000 mile, coolant. Don't mix anything with it that is not the same coolant from MOPAR. Other coolants are not compatible.  

yep, like ftgiles said. also, when you do the oil changes, it's recomended to check and or grease the steering linkages and drive line.
