Detailed Description

KYB Mount Components are engineered as OE-style replacement parts for suspension service. The SM5906 strut mount is made to replace hardened or worn upper mount components that can cause clunks, vibration, and excess cabin noise. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. Compatible with Hyundai Kona, Hyundai Elantra, and Hyundai Elantra GT rear upper applications listed above, KYB SM5906 supports a clean, direct-fit repair.

Common Problems This Part Can Address

  • Suspension noise from worn upper mount insulators
  • Road vibration transferred into the body or cabin
  • Harsh impact feel over bumps and rough pavement
  • Steering or alignment concerns related to worn mount hardware
  • Clunking or looseness from deteriorated rear upper mount components

Installation Notes and Tips

Verify the vehicle year, model, and rear upper position before ordering. Inspect the surrounding strut assembly, bearing surfaces, and related suspension components during replacement. Professional installation is recommended because strut service requires proper suspension handling and alignment checks after repair.
