1997 dodge ram 1500 is stuck in 4 wheel drive.

The front hubs operate using a vacuum actuator in the hub of the front axle. This arrangement is used by ford/

See the vacuum hose connection in the blue box.

Jeep and others use a actuator attached to the axle housing.

Hope this helps?

Sounds like you either have a vaccum leak or your 4 wheel drive actuator is not working to engage the front differential.On my 98 ram there is a black and red plastic lines that are used for the vaccum lines. They are underneath and go from the transfer case to the front axle, check to see if one or both might be cracked or broke completely.If the lines are good then it could be your actuator on the front axle. A new one is about $93 at advance auto parts and not very hard to replace

might be the vacuum switching valve on the front differential

the ansew i found is replacing the seal around the joint and from both end removing it and cleaning it out i had rocks in mine from going threw water and mud ita a all day deal but a twenty doller fix axle shaft oil seal is all i had to replace

There's not really a best way. If the axle half shafts bolt to the housing just drop it right out. If not you'll have to remove both half shafts from the wheel hub. Disconnect the drive shaft, and drop it out.

shift into 4wd and move truck a couple of feet.
if light is still off, park truck block the wheels set the park brake jack right front wheel and try to hand spin the wheel if wheel doesn't turn 4x4 is functioning properly but there is a wiring problem use an ohmmeter to check the 4x4 switch wiring fuse and bulb
if wheel turns freely the front axle or transfer case is not engaged
attempt to hand spin the front driveshft if the driveshaft will spin the transfer case is not engaged check the transfer case shift linkage, problem is in linkage or transfer case internals
if the driveshaft will not spin the transfer case is engaged properly
with trnsmission in neutral or park start engine measure vacuum on the two vac lines at front axle shift motor . one line should have approx 20" vacuum. other line should have none
if no vacuum measured look for vac leak or bad vac switch
if both lines have vac look for a bad vac swithc or ruptured cad actuator diaphragm
if one line has 20" +- VAC
move transfer case lever to 2wd measure vac again lines should have swapped vac signals
if no vac switch bad or 4wd shift likage needs adjusting
if yes vac motor bad or stuck or shift fork stuck
remove vac shift motor from the axle attach vac lines to shift motor engage disengage 4wd
does shift motor plunger move at least 1/2 inch
no shift motor bad
yes check axle shift fork and vac motor for binging

i would take it back to the repair shop who repaired the tranny! your overdrive is not working , i had the same problem, good luck!!

There are some vaccum lines that go to your axle. there is a disconnect there and a switch that lights up your dash light when engaged. I would first make sure they are still connected and not damaged. The vaccum signal to engage and disengage comes from the top of your transfer case right under the shifter boot. To test if you disconnect is working, apply vacuum to one or the other side of the diaphram for the axle disconnect and try it out. otherwise you may have lost vacuum somewhere or you have a bad switch on your transfer case.

That is a dealer item there are some aftermarket manual actuators but they also have their own problems such as not fully engaging or disengaging. Find a Chrysler dealer and fork over some cash.
