Hyundai Sonata & Kia Optima Front Left CV Axle Shaft Assembly

This BDFHYK front-left CV axle shaft assembly is an OE-style aftermarket replacement based on the original listing information for Hyundai Sonata 2015-2019 and Kia Optima 2016-2020 applications. For owners comparing a Hyundai Sonata CV joint, it is important to verify the driver-side front position, vehicle configuration and removed axle before installation.

These symptoms can also come from tires, wheel bearings, engine or transmission mounts, brakes and suspension components, so the source should be diagnosed before replacing a CV joint for Hyundai Sonata or Kia Optima.

Before choosing a CV joint Kia Optima assembly, compare the same physical details and reference numbers.

When to Inspect a Hyundai Sonata or Kia Optima CV Joint

Customers researching a CV joint Hyundai Sonata or CV joint Kia Optima often need to separate axle-related symptoms from other front-end problems. Inspect the driver-side axle when the vehicle shows:

• Clunking as torque changes between acceleration and deceleration.
• A cracked boot, loose clamp, measurable joint play or visible shaft damage.
