4x4 Front Differential Axle Actuator, 4WD Hub Lock Actuator Kit Compatible with 2006-2024 Ram 1500, Replace Part# 600-399 52114387AF 68399418AA Disconnect Actuator W/Shift Fork Pad

Bought for a 2021 ram 1500 4x4, Fast shipper, part worked, and fit as described. Fixed my 4x4 serv light that would flash.

Junk. Installed and it started leaking where the two halves were mated. They sent me another and it leaked too. Chinese junk.

Works great but make sure you apply a gasket sealer. Fluid will leak with the supplied gasket

Its works great. No problems

I just got it today 6/12/25 I got it put in and the multiple lights are off on my Dash now. Did not have time to test it or drive the truck but I will do a update if I have any problems. So the quality compared to the Mopar one is noticeable but for the price that is to be expected. I didn't want to spend a lot of money on Mopar and it wasn't my problem. I had traction control light/ trailer brake and 4x4 service lights on dash now they're off so time will tell. So if you are having this problem and no codes come up this might be your problem as well
