52773-2G000 BUSH FAQ

Why does the rear of my car feel unstable?

When the rubber inside the 52773-2G000 separates, it allows the rear wheel knuckle to shift slightly, causing a “wandering” sensation on the highway.

Should I replace both sides?

Yes. Suspension components on the same axle experience identical wear. Replacing both ensures balanced handling and prevents the vehicle from leaning to one side.

Questions and Answers

What is the role of this component?
It serves as a flexible pivot point between the rear suspension arms and the rear wheel knuckle, dampening vibrations and maintaining wheel geometry.
Which vehicles utilize this specific part number?
This part is designed for the Hyundai Sonata (NF/YF) and Kia Optima (MG/TF), generally for model years 2006 to 2015.
How many of these are on the vehicle?
Most rear multi-link setups use two of these bushings per side (four total) in different knuckle pivot points, though the 52773-2G000 is a specific size for primary control arm mounting.
Can I replace just the bushing instead of the whole knuckle?

Yes. Replacing the bushing is a cost-effective alternative to replacing the entire rear knuckle assembly, provided you have access to a hydraulic press.
