The X3M50 I got came from the factory without wheel locks, and I decided to buy the "optional" wheel locks and then Install them myself (the dealer charges $100.00 to do so).As I was Installing the wheel locks I noticed that the torque on all the lug bolts for the wheels on the DRIVER'S SIDE of the X3 NEEDED TO BE RE-TORQUED o the 101bs Ft/140Nm.
ALL of the lug bolts on the PASSENGER SIDE of the X3 were AT the correct Torque.
My X3 has 1,185 Miles and 3 months of use. So, this isn't even on the list of items to be checked AT ALL. I am glad that I decided to buy and Install the wheel locks myself.
This should be a 'F Y I" for all , and beware that evidently; close attention is due to all the wheel lugs ON ANY VEHICLE.
