Delphi TD4342W Suspension Control Arm Bushing - Front Upper

Front Upper Control Arm Bushing for Toyota and Lexus

Delphi TD4342W is a front upper suspension control arm bushing built for select Toyota and Lexus applications. It uses a rubber-steel construction and pressed mounting style to match OE-style suspension service needs on vehicles such as the Toyota 4Runner, Toyota Tundra, and Lexus GX460.

Key Features

• Rubber-steel construction for suspension control arm service
• Pressed mounting type for OE-style installation
• Front upper position
• Gray finish
• Standard replacement grade
• Dimensions: 61.8 mm length, 15.0 mm inside diameter, 46.3 mm outside diameter
• Delphi OE-based dimensional and material analysis for fit consistency

Detailed Description

The Delphi TD4342W suspension control arm bushing is engineered for front upper suspension locations on a wide range of Toyota and Lexus trucks and SUVs. It is a direct replacement-style part for applications including the 2003-2022 Toyota 4Runner, 2000-2006 Toyota Tundra, 2001-2007 Toyota Sequoia, 2007-2014 Toyota FJ Cruiser, 2003-2009 Lexus GX470, and 2010-2022 Lexus GX460. Delphi validates its aftermarket steering and suspension parts through dimensional and material analysis, along with extreme temperature and salt-spray testing, to support OE-level compatibility and durability. This part cross-references Toyota 48632-34010 and MOOG Chassis Products K200910 for the same application. If you are replacing a worn Delphi TD4342W bushing on a Toyota 4Runner or Lexus GX460, this part is built to match the original front upper control arm location and pressed-in service design.

Common Problems It Can Address

• Front suspension clunking or knocking from worn control arm bushings
• Excessive front-end looseness or wandering
• Uneven tire wear caused by suspension play
• Steering instability over bumps and rough roads
• Visible cracking, separation, or deterioration in the original bushing

Installation Notes and Tips

TD4342W installs in a pressed mounting location, so the control arm typically must be removed and the old bushing pressed out before the new one is installed. Verify the front upper position and compare the dimensions to the original part before installation. Because mounting hardware is not included, reuse or replace related hardware only as needed based on the vehicle service procedure.

Quality Assurance

Delphi applies OE-focused testing to this bushing, including exposure to temperatures below -40 degrees C and above 120 degrees C, plus 720 hours of salt-spray testing. That validation supports consistent performance for front upper suspension service on Toyota and Lexus applications.
