Car Rig Issues - Side wheels dont have collision

I have been having problems running my newly rigged car from blender inside UE4, when i press “Play” the car lands properly, wheels operate properly, everything is good except for the side wheels of my car (They sink halfway into the terrain as if they have no collision response at all) while the other half is working fine. (PS. in the physics simulation both sides of the wheels work perfectly fine, the problem only occurs when i try to run my car on any sort of rigid body when i hit play.

been trying to solve this problem for over 4 days now, help would be really appreciated!
