Question about 2001 Dodge Ram 2500 Truck
When I try to engage the four wheel drive on my dodge 2500 the transfer case will lock in but the vacuum actuator dosn't engage. Took vacuum lines off at the transmisson and there is no air getting pushed through the lines. Need to know my next step, or other checks to perfrom.i have a 2001 ram 2500 when i enagage the 4 wheel drive the transfer case engages but the front axle doesnt since it has stopped workin it has worked one time when i checked it but it hasnt ever since and no light turns on
I beleive your 4wd mechanism has become faulty and the coupling between the front axle and the transfer case is broken or loose . Kindly check it

You wont feel air being pushed through it. it should have a suction to it. buy a cheap hand vacuum pump with a gauge. take the line off at the axle actuator and apply vacuum to it and make sure it is working. if it checks ok remove the lines from the transfercase switch start the vehicle and see if any show vacuum. you should be able to hook the pump up to it and see the gauge move. if the gauge moves you have vacuum and most likely the switch is bad. if you dont have vacuum follow the line up til you find the leak

Welcome to Fixya! You need to replace the Vacuum Canister. Should be Mounted on the Inner Fender on Drivers Side.
