The front differential is an "open" differential. No limited slip components there.
The front differential uses 80w90.
The actuator of the Dodge Ram 4x4 is located on the top of the front differential. Depending on the year, the actuator is either vacuum or manually operated.
Dodge 2500 and 3500 4x4 trucks use a split front axle that is engaged with vacuum lines that run from the intake to the transfer case then to the front differential. That was true up till 2002, after that the shifter on the axle was electric if it had one at all.
On a Dodge truck, the vacuum switch is on the transfer case.On a Dodge truck, the vacuum switch is on the transfer case.
I do not think that there is a front axle disconnect. If there is then it is vacuum controlled and the problem is either a switch or a broken line.I do not think that there is a front axle disconnect. If there is then it is vacuum controlled and the problem is either a switch or a broken line.
You unscrew the plug on the front cover, and ad 75w90 to the bottom of the hole.
Check the vacuum line to the front differential.

The front axle is engaged by vacuum. Most common is a cracked or leaking hose but can also be holes rusted in the vacuum canister. This canister is mounted on the front axle, passenger side. Sometimes they just get gunked up and need cleaned and lubricated to get them working again. When it is working properly the vacuum pulls a fork inside the axle. That fork slides a gear that connects the wheel to the differential axle. So without vacuum the 4x4 cant engage. In most cases it comes down to issues near this canister. Check it and see.
if 4x2 only 1 differential which is the pumpkin between your rear axle, if 4x4, there will be a transfer case at the front of the vehicle coming off of the transmission going to front drive shaft and front differential.
There is no vacuum switch. There is an electric actuator on the front left of the front end assembly right in front of where the cv shaft goes into the differential case and an electric actuator on the rear right of the transfer case.
It is a vent tube to let pressure out of the differential housing.
There is a cable for the front differential. One end goes to the front differential, one end goes to a vacuum actuator under the battery. That is what most commonly is wrong with those vehicles.
Yes, the problem is probably the vacuum actuator for the front differential, it is located in front of the battery, get real one from Chevrolet, I had two from NAPA fail within a year.
The vacuum actuator is on the right side of the axle. The electrical switch is on the actuator. The vacuum switch is on the top of the transfer case.
Front axle is a 9.25 American Axle Rear axle is a 10.5 American Axle
The front axle on these trucks have a mechanical actuator that locks the front differential in. They have used vacuum, thermal and mechanical means for this. The mechanical is the most reliable. This is a common fail point on the Chevys/GMCs. It is located on the front axle next to the differential.
Underneath the the plastic cover on the front differential.
Yes, the shaft is still connected to the front tires through the front differential, so it will turn while driving.
maybe vacuum hoses have come off front differential solenoids or from somewhere else this system is vacuum actuated then electric clutch engages
the rear is called a 9 1/4 the front, if 4wd, is a Dana 44
probably a vacuum system leak. Older dodge trucks had the front transaxle engage by a vacuum line. Make sure your pump is working, and that there are no leaks. Then it should engage
