Detailed Description

This suspension knuckle bushing is built for rear lower rearward and rear lower forward positions, including rear lower forward to lateral link applications on select models. It is a fitment-specific replacement for Nissan GT-R, Nissan Murano, Nissan Pathfinder, Nissan Quest, INFINITI QX60, and INFINITI JX35 rear suspension service. This part number, Dorman 540-151, is engineered to restore the bushing interface at the knuckle where wear can affect suspension alignment and rear-end stability.

This part cross-references MOOG Chassis Products (e.g., K200966, K202136) for the same application.

What It Helps Address

• Rear suspension looseness or excess movement at the knuckle
• Clunking or knocking from worn rear suspension bushings
• Uneven rear tire wear related to bushing wear
• Suspension alignment issues caused by deteriorated rubber and steel components
• Restoration of OE-style rear lower suspension connection points

Installation Notes and Tips

Verify the rear suspension position before ordering, since this part is listed for rear lower rearward and rear lower forward locations depending on vehicle application. Confirm the original bushing dimensions and compare the OE part number when servicing Nissan Murano, Pathfinder, Quest, GT-R, or INFINITI QX60/JX35 models. Professional installation is recommended because suspension bushings typically require proper pressing and alignment checks after replacement.

Quality Assurance

Dorman manufactures this bushing as a standard replacement part and subjects it to engineering and testing checks to support reliable OE-style service on the specified vehicles.
