I thought so, but I am confused. I don't see any wires at all attached to any of my moving front end parts. MY Trifecta light as been on for over a year, but everything works. Just have to emergency brake like I was taught, tap/remove,etc. If the speed sensors aren't working properly in front what else is connected to mechanically moving parts. These old X5's don't have the AWD engagement plastic gear. I would think the biggest issue is weight distribution when you remove the front drive system, transfer case. Just curious.
