i haven't had my jk for long just hit the 5000 mile mark and i was wondering, what kind of maintenance people do on there jeeps? like from basics to the extreme and is there anything that i should really do besides changing oil, and checking air filter and little stuff to keep my jeep running long?

also just a side is there any really big like problems people have run into, just stuff i should be looking for that could cause a major problem?

 

have a look at your service manual for a list of things to check.
Don't have one?? Go to the Jeep website and get a list off there

Not sure what your looking for as far as things to look out for, but damn near all maintenance can be performed with basic tools...the only thing you'll have a problem with is the transmission flush, the manual needs a special tool that can be fabricated, just search for it here

 

I changed all my fluids (besides p/s and brake fluid) at 1,000miles. I considered it "break-in" period. Was surprised how dirty the lube from the axles got so soon..

 

I would change out the fluid in the differentials, i think i did mine around 2k (i hate leaving factory fluid in as I like watch my fluids carefully). The front wasn't too bad (I had only used the 4wd a couple time at that mileage), but the back was filthy, glad i changed it out. Check out the write-up in the project JK section if you wanna see it before you do it. It is really easy and will help w/ peace of mind. Most importantly enjoy your new JK!

 

For normal driving I would say stick with what is in the owners manual as far as routine maintenence goes.

It also doesn't hurt to do a quick once over every time you fill up, after all you have enough time while standing around at the pump. Pop the hood, check fluid levels, tire pressure, take a peek underneath to check for leaks, etc. If you don't go off road a lot, it's not a bad idea to make sure that all the functions work every once in a while; shift into 4hi and 4lo, disconnect sway bar, actuate lockers, etc. The AC is also a self lubricating system, and it helps to run it ever so often even in the winter to keep all the seals lubricated (I always use it together with the defrost with the temp on high). It's surprising how these simple checks can help prevent significant problems later on or identify faulty equipment before you are in a situation where you need them.

If you wheel alot, it is a good idea to run a more vigorous maintenance schedule. The more you are off road, the more important it is to change fluids more often, as contaminents are more likely to get in and the fluids will break down faster under extreme conditions. Diffs seem to be the biggest victims.

 

If and when you add a lift, you should check your suspension, steering and driveline components much more frequently, particularly if you wheel hard or often.

And notice that many aftermarket suspension and steering parts have Zerk fittings for lubing, where as the stock parts don't require it. Don't forget them.
