Re: Jeep Maintenence
Water and the stuff it brings with it is your biggest enemy. Any time you get in water hub deep or more you should grease everything that can be greased.
You should also change the transmission, transfer case and differentials. Any oil that comes out milky has taken it water. Either correct where it's entering or continue to change it after every immersion.
Also after every wheeling trip where there's dust in the air you should inspect the air cleaner. The old standard is that you lay down a sheet of newspaper and bang the flat surface of the air filter on it. If any dust can be knocked loose the element should be changed. Another test is to put the filter around a lightbulb. If you can see light through it, it's still good. I think that test is way too permissive.
Those procedures are neither time nor mileage dependent; they need to be done after every wheeling trip. My Jeep gets very little use, so I change oil and filter twice a year, which may only be a few hundred miles of use.
Something I've done since the Jeep was new is to annualy remove the plug wires, clean them with carburetor cleaner, work silicone grease into the places where the boots meet the wires, and then spray them liberally with silicone spray. They lasted more than 28 years, and never let the electricity out.
That's all I can think of that varies from the maintenance you'd do for any car of similar mileage, age and use.
