Detailed Description

This Dorman 540-532 stabilizer bar bushing kit is made for front sway bar service where worn bushings can affect suspension control and noise levels. The rubber and elastomer material helps restore the stabilizer bar’s mounting interface, supporting consistent bar movement and proper suspension response on 2004-2020 Toyota Sienna, 2008-2019 Toyota Highlander, 2007-2018 Lexus ES350, 2013-2018 Lexus ES300h, 2010-2015 Lexus RX350, and 2010-2015 Lexus RX450h front applications. This part cross-references MOOG Chassis Products (e.g., K90546, K200616) for the same application.

What It Helps Address

• Sway bar clunking or rattling from worn front bushings
• Excessive play at the stabilizer bar mounting point
• Suspension noise over bumps and uneven pavement
• Reduced steering feel caused by deteriorated bushing material
• Service needs on front stabilizer bar mounts for Toyota Sienna, Highlander, and Lexus ES/RX models

Installation Notes and Tips
