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

Here is a general vacuum hose and line placement diagram for a 2001 Dodge Ram 1500 4x4:

1. The vacuum line from the engine intake manifold should be connected to the vacuum reservoir tank.
2. The vacuum line from the vacuum reservoir tank should be connected to the vacuum actuator on the front axle.
3. The vacuum line from the vacuum actuator on the front axle should be connected to the transfer case.
4. The vacuum line from the transfer case should be connected to the vacuum actuator on the rear axle.
5. The vacuum line from the vacuum actuator on the rear axle should be connected to the vacuum reservoir tank.

It is important to note that the specific placement and routing of vacuum hoses and lines can vary depending on the make and model of your Dodge Ram 1500, as well as any modifications that may have been made to the vehicle. It is always recommended to refer to the manufacturer's instructions or a repair manual specific to your vehicle for accurate information. Additionally, it may be helpful to take pictures or label the hoses and lines before removing them to ensure proper reinstallation.

check the front drive shaft spline or "U" joint at the transfer case
splines on this shaft wear more quickly that the rear drive line
as the operation angles for the front diff are more acute that the rear shaft

Front or Rear ?

Not the Transfer Case Chain ????

Change the fluids front,rear & transfer-probably
won't help, but you get to see if any metal comes out

follow the rear drive shaft from the rear axle and where it meets the front is where the transfer case is

I would definitely check the fluid level in the transfer case first. If that's OK, it MAY be the tires.

is the shaft from the transfer case to the front axle spinning? Check to see that your locker solenoid is still plugged in there's a plug on the drivers side rear of the engine about 10 inches from the starter that's the plug to the locker solenoid. If its plugged and your front drive shaft from the transfer case spins your locker solenoid is likely bad.

pull the gear cover off the front and on the rear probably the same procedure if the is not a drain plug

TPIM PROBLEM , MUST HAVE COMPUTER FLASHED AT DEALERSHIP

first i would check the tires , are they cupped or chopped on the tread? run your hand over the tread and see if it feels rough and uneven. take the truck to a auto repair shop and have them jack both front and rear axles off the ground, put the truck in 2 wheel drive and run the speedometer to the speed you usually hear the roaring noise, if you don't hear the noise , put the truck in 4 wheel drive, turn off the traction assist if it has one and run it to the speed you would hear the noise. if you hear the roaring noise with tires off the ground, the problem is in the drivetrain, (engine, transmission, transfer case, u-joints, differentials or the front left or right cv halfshafts or u-joints). the older models (97 98) had the front two driveshafts from the differential turning all the time, they engaged in 4 wheel drive from the transfer case and a solenoid on the front differential. depending on the miles you have on this truck, the most likely areas i would look at would be the tires, u-joints/cv joints, and front and rear wheel bearings. thanks and good luck.
