Brake fluid should be changed once in the 2 years. This is because it is hygroscopic, ie it attracts water from the air. These water particles will start boiling at 100 °C and become vapor, which makes the brakes feel spongy or in worst case completely loose braking force. The 2 year interval is a safe service interval.
The service manual doesn´t mention anything about changing the power steering fluid, but i would change it once. Could extend the life of the pump and seals.
Also coolant needs to be changed once in a while. Eventhough the coolants nowadays are longlife and seem to have a service life of 5 years, i wouldn´t recommend to wait that long. There are many horror stories about electrolysis inside the cooling system, where aluminum is braking down and causing leaks (especially on radiator and heater core).
How do I drain out these fluids?

Re: Can't get my wj outta 4lo?

For diffs remove the diff cover. There are writeups about this. Some people just suck the fluid out via the fill hole, but in that way jou won' t get all fluid/ metal particles out, so bad idea.
For tranny you have to remove the pan. Messy job, but not to difficult. There are writeups about that as well. I could give you directions, but lets do that one at a time, otherwise this will become an endless reply. Tell me where you want to start.

Don't know that bg44k, where do you put it in and what does it do?

44k is a fuel system cleaner (the best) and it goes in the gas tank (or if you have the tool right into the fuel rail) oil change is recommended because it really cleans the gunk out

...and sometimes deposits crap into the oil somehow...wish my understanding of an engine was more than limited.

How hard is an oil change?

You are talking now about the engine oil, right?
This is very simple. although i never do it myself anymore. This is the only thing for which i take it in, since the shop where i buy it, changes it for free. No fuss of laying on the ground and getting rid of the old oil afterwards.
But in case you want to do it yourself, you will need the following;
1) Some recipient to catch the old oil. There are special recipients available for this, but it should have at least 7 lts capacity (6 lts coming out plus some space so that you can take it away without spilling)
2) There is a sealing ring under the drain plug. Sometimes it can be reused, but to prevent leaks i prefer to change it. Not sure about the size.
3) Best is to change the oil filter with every oil change. You will need a new filter and a spanner to remove the old filter. When you remove the old filter, some oil will come out, but the filter itself is full of oil, so take care. Installing the filter is just screwing it on until the seal touches the metal surface and fasten it 1 turn more (this can normally be done by hand), but first clean the sealing surface on the engine and put some fresh oil on the new filter seal.
4) Best is to change the oil when warm/hot, because then its thinner and will flow out more easily and take out most of the dirt as well. Only take care in not touching exhaust parts or other hot engine parts and use gloves to prevent burns. Wait with re-installing the drain plug until no more oil drips out.
5) After re-installing the drain plug, fill the engine with oil until the level has reached the full mark on the dipstick (on level ground). Now start the engine (after checking that all tools/rags etc are removed from the engine bay) and check that the low oil pressure light goes out within a few seconds. After running for a minute or so, switch the engine off and check for leaks at filter and drain plug. Wait a few minutes after switching the engine off (to allow the oil to drain back to the carter) and check the oil level again, since it will drop a bit due to filling of the oil filter, and fill until full mark.
Take care not to spill oil on the ground and don´t flush it through the gutter, but take it in for recycling.

Yep, motor oil. I'd like to try it at least once...seems easy enough, now to find rotella t5!

Rotella t5 10w30 is a oft-used oil in the 4.0, or at least I thought, because of its high amount of zinc.

Does everyone like going with the standard mopar oil filters?

Headed over to carid.com, my options are purolator, full, k&n, mopar, and Bosch.
