TrakMotive BM-8162 front left CV axle shaft for the 2015-2018 BMW X4 and other vehicles sends drive torque to the front left wheel. Its constant-velocity joints let the wheel keep turning while the car steers and the suspension moves.
A clicking or popping noise in turns, vibration while driving or grease thrown from a torn boot can mean the axle is worn. Before you replace it, rule out a worn wheel bearing and an unbalanced tire, since either one can also bring on noise or vibration. This listing is a single axle for the front left; the front right is a separate part, and shops normally replace both together.
It fits the 2015-2018 BMW X4 and the 2011-2017 BMW X3, and the front left position takes one axle on both.
