TrakMotive HO-8591 front right CV axle shaft for the 2015-2020 Acura TLX carries drive torque to the wheel. This TrakMotive CV axle flexes at both joints as the suspension moves and the wheel steers.
A clicking or popping noise in turns, grease thrown from a torn boot, or vibration under acceleration can mean a worn axle joint. A worn wheel bearing, a tire out of balance or a loose mount can be behind similar noise or vibration too, so find the cause before buying.
This is a direct-fit replacement for the 2015-2020 Acura TLX, which takes one on the front right. This listing is one side; the front left is a separate part, and the other side of that axle is normally done at the same time.
