Excessive lug nut torque transcends from the hub to the bearing, constraining its normal operation.
Why is the left bearing which first bears the damage regardless of the cause?
Because in the V6 Escape the left front mass to be rolled is much more than the right front mass.If to that you also add the driver's mass, the difference gets even bigger and thus the additional strain that the front left wheel bearing has to deal with causes it to be the first to fail.
