Delphi TD1122W Suspension Control Arm Bushing - Rear Lower Forward Inner

Delphi TD1122W Rear Control Arm Bushing

Delphi TD1122W is a suspension control arm bushing built for rear lower applications on select Mercedes-Benz models. It uses rubber construction and a press-fit mounting style to match OE-style suspension service needs on vehicles such as the Mercedes-Benz C350, E350, and GLK350.

With OE-focused dimensional and material analysis, this bushing is made to align closely with factory fitment requirements. Delphi also subjects its steering and suspension components to extreme temperature and corrosion testing, helping verify performance in demanding road conditions.

Detailed Description

Delphi TD1122W is a rear lower control arm bushing engineered for Mercedes-Benz suspension service where OE-style dimensions and material consistency matter. The rubber construction helps restore the original bushing interface in the control arm, while the press-fit design supports a factory-style replacement process. This part number, TD1122W, is listed for rear lower forward inner and rear lower rearward positions depending on the vehicle application.

Compatible With Mercedes-Benz C250, C300, C350, C230, C280, C63 AMG, E250, E300, E350, E400, E550, GLK250, and GLK350 applications across the listed model years. Use Delphi TD1122W when replacing a worn rear control arm bushing on Mercedes-Benz C350 or E350 suspension systems that require the specified OE-style dimensions.

Common Problems It May Address

• Rear suspension clunking or knocking from worn bushings
• Excessive control arm movement under load
• Uneven tire wear related to suspension looseness
• Imprecise rear suspension response during braking or cornering
• Cracked, hardened, or deteriorated rubber bushings

Installation Notes and Tips

• Press-fit installation typically requires a bushing press or equivalent service tool.
• Confirm the vehicle position before ordering: rear lower forward inner or rear lower rearward.
• Inspect the control arm and surrounding hardware for wear before installation.
• Verify dimensions against the removed part when servicing Mercedes-Benz C-Class, E-Class, or GLK applications.

Quality Assurance

Delphi applies OE-focused engineering and dimensional analysis to support fitment consistency. The part is also tested for extreme temperature exposure and salt-spray corrosion resistance as part of Delphi’s validation process for aftermarket steering and suspension components.
