Making wheels rotate the same (differential lock)

Hello, I have a problem with making my wheels rotate at same speed, like the differential lock works. Any idea how I can make it? I am using ue 5.3 version.

More context: I am making a tank movement system, everything works but not wheels, I mean, they work but I don’t want them to rotate at max speed when half of wheels are in the air and other half at the ground, I want to make every single wheel at one speed, for this example I need the slowest rotation of one on wheels in vehicle and apply this for other. It can be done visually, It don’t need to be physically accurate
