Delphi TD4027W Suspension Control Arm Bushing - Front Left Upper

Front Left Upper Control Arm Bushing

Delphi TD4027W is a standard replacement suspension control arm bushing for the front left upper position. It is built for direct-fit service on select Acura, Honda, and Isuzu applications, including Honda Accord, Honda Odyssey, Acura CL, and Isuzu Oasis models.

With OE-focused dimensional and material analysis, this bushing is made to match the original fit and function expected in suspension repair. Delphi also validates its steering and suspension parts through temperature and corrosion testing to help support consistent performance in demanding conditions.

Detailed Description

Delphi TD4027W is a suspension control arm bushing engineered for the front left upper location on select 1994-1999 Acura, Honda, and Isuzu vehicles. It fits 1997-1999 Acura CL, front left upper; 1996-1999 Isuzu Oasis, front upper; 1995-1998 Honda Odyssey, front left upper; 1995-1997 Honda Accord, front left upper; and 1994 Honda Accord, front upper. This part cross-references MOOG Chassis Products K90458 for the same application.

As an OE-style replacement, this bushing is suited for restoring the control arm’s pivot point and helping maintain suspension geometry on vehicles such as the Honda Accord and Honda Odyssey. Delphi TD4027W is built with compatibility in mind for the original mounting dimensions and material requirements of the application.

What It Helps Address

• Excessive suspension play at the control arm pivot
• Clunking or knocking from worn front suspension bushings
• Uneven tire wear related to suspension looseness
• Steering wander caused by deteriorated bushing support
• Loss of alignment stability after bushing wear

Installation Notes and Tips

Verify the vehicle’s year, make, model, and front left upper or front upper position before ordering. Compare the original bushing dimensions, including length and inside diameter, to confirm application match. Because this part is used in suspension service, professional installation and a post-repair alignment are recommended after replacement on compatible Honda Accord, Honda Odyssey, Acura CL, and Isuzu Oasis applications.

Quality Assurance

Delphi applies OE engineering experience to its aftermarket steering and suspension portfolio. This part is tested across extreme temperature ranges and salt spray exposure, and its fit is supported by dimensional and material analysis to help maintain OE-style compatibility.
