Center differential

IF you are in constant 4wd then you will not have a centre diff unless you have an AWD. The difference is that AWD transfer cases have a centre diff that allows different road speeds between the front and rear diffs as in going over speed bumps and dips ion the road It is the same operation in the front and rear diffs that allow one wheel to go faster than the other when cornering. However in 4wd drive there is no diff action in the transfer case and both front and rear axles drive at the same speed regardless of speed bumps and dips in the road . This action produces what is known as torque wind up which results in the handling characteristics. This torque wind up places stress on all the drive line train and results in failures such as .that you describe.. This wind up is not noticeable when driving on loose surfaces slippery surfaces or in mud as it is allowed to escape when the wheels spin . If you have an AWD with diff lock capabilities then check that the diff lock is operating correctly

Is doing a transmission flush the same as changing the differntial fluid?

No, a transmission flush replaces the fluid in your transmission. A diff. service would replace the fluid in the rear end also the transfer case and front diff. if you have a 4 wheel drive truck.

Need diagram to change fluids in transfer case and front and rear diffential for a 2003 dodge ram 3500 4x4

This is pretty straight forward once you have a few basic tools. You will need a suction pump and a bowl/bucket type container to put the old fluids into.

Both the front and rear diffs should have a rubber inspection plug you can remove to pump the old stuff out, and the new gear oil in.
Synthetic fluids last longer and work better.

The transfer case should have two threaded allen plugs (or similar) that are removed to drain and then refill the T case. Remove bottom then top to drain. Reinstall bottom then refill.Then reinstall top.

Need to know fluid capacity of differential (FRONT/REAR)and transfer case and how to change and what problem indicators to look for. 2004 Jeep Liberty 3.7L Automatic Thanks

Dont remember specific amounts for those but they are "fill till it comes out of fill hole" On flat level ground. About three gallons should do it with some leftover. Check with your parts house or dealer to make sure of what goes into the transfer case...many now use dextron III not gear lube.
Any excessive metal flakes in old lube indicates a problem with internal parts wear for either diffs or case. (everything wears so there is always some, it just shouldn't look like glitter paint)
There should be tow approx 1" nuts on the back of the case lower one is drain, upper to fill. Diff cover needs to be removed to drain. Fill through plug on cover.

My rear pumpkin ball /transfer case is leaking . is there a seal to change

If you are talking about the rear diff case. The seal can be change usually either a rubber gasket or hi temp silicone, just scrape off the old gasket from the diff and the the cover. Make sure its clean before you put on the gasket or silicone whichever its has. Put a good amount of silicone around the diff cover and bolts holes. Make sure to get some rear diff fluid and fill it back up w/funnel. Its either on the diff cover w/ a rubber cover or on the side of the diff itself w/ 3/8 ratchet. Fill till up till it starts to drip out then tighten back up.

1995 AWD Jeep with odd moaning sound from rear when turning sharp

If transfer case has not been serviced in some time, Even if it does not cure the problem it's likely to prevent a different one later. So that is worthwhile. I'd check the rear diff fluid as well. It's difficult to diagnose noises online but I'd try to isolate which side the noise is on and check both axle bearings. (outside chance it could be a diff carrier side bearing, but get to that after all other options have been eliminated.)
