How to properly rig a vehicle in Blender for 4.15?

I have been trying for days with no luck because I keep running into the same problem where all the collision collapses onto the root bone in the Physic Asset. From all the limited sources I have found it seems that this image is how I should rig the vehicle but it just doesn’t want to work

Can someone please help me? I really want to make a vehicle for my game but I just can’t do it. There are a few outcomes that will happen after I import the FBX to unreal.

A1) The physic asset automatically created will not make collision only for the body and ignore the wheels
A2) Adding the collision to the wheels and simulating the physics will cause the car to fly around the screen and go absolutely berserk for no reason

B1) The physic asset creates all the collision but after resetting them to setup the bounds correctly (car body is a box, wheels are sphere’s) the same issue happens in A2

C1) Everything somehow works and simulating doesn’t cause the vehicle to fly around the screen and it behaves like the Sedan in the vehicle example project

But no matter what outcome happens if I setup the vehicle correctly in unreal and hit play the wheel’s collision will snap to the root bone at the bottom middle of the vehicle and wobble around like a unicycle

PLEASE! I need help!
