2017 cub cadet challenger 550. 4x4 and front diff lock won’t engage

[David Schwalm]

I have a 2017 challenger 550 that will not go into 4 wheel drive. I’ve checked fuses, all are good, when I turn the key to on, and press the 4x4 button I can hear the actuator running , the front tires in the dash indicator light up as though it is engaged, but no 4 wheel drive. When I activate the front diff lock I can also hear the actuator but it does not show the x in the front axle on the dash. Any suggestions would be appreciated!!

I needed to use the 4 wheel drive on my Challenger and it would not engage. I checked all the fuses and they are good. With the key in the on position and machine not running I can hear the actuator run when the switch is pressed, and the indicator on the dash lights up but it does not go into 4 wheel drive. The front diff lock actuator runs when it is pressed but the indicator x does not show up on the dash, any suggestions should be appreciated!

@David Schwalm your topics have been merged since they are relatively the same.

The manual calls for gear to be in neutral to shift into four wheel drive. Could this be the problem?

It does the exact same thing with the machine in neutral, all the electric diff motors run, but no 4 wheel drive
