Detailed Description

MS504363 is a Mevotech suspension control arm bushing engineered for the rear upper inner location on select GM crossover platforms. The natural rubber material helps restore the bushing interface at the control arm, while the press-in design supports a direct replacement service during suspension repair. With its specified inside and outside diameters, this bushing is sized for the intended mounting point rather than a universal application.

• Addressing rear suspension looseness or excess movement
• Restoring proper control arm bushing support
• Reducing noise caused by deteriorated rubber suspension components
• Servicing GM crossover rear suspension wear points

Installation Notes and Tips

This is a press-in bushing, so installation requires proper suspension service tools and control arm removal. Inspect the control arm and surrounding hardware for wear before installation, and verify the rear upper inner position before pressing the new bushing into place. Confirm vehicle application by year, make, model, and position before ordering.
