TrakMotive CV Axle Shaft P/N:BM-86042
TrakMotive HO-86042 rear right CV axle shaft for the 2019-2023 Acura RDX and other vehicles carries drive torque to the wheel while the suspension moves.
A torn boot with grease around the wheel well, clicking on turns or vibration under acceleration can mean a worn joint. Before you replace this CV axle shaft, rule out a wheel bearing or tire imbalance, which can cause similar signs. One shaft goes on each side of the rear axle; this listing is the rear right, and the rear left is a separate part.
This rear right CV axle shaft fits the 2019-2023 Acura RDX and the 2021 Acura TLX.
