Detailed Description

Delphi TD1105W suspension control arm bushing is built around OE-focused dimensional and material analysis to support proper fitment between the original suspension design and the replacement part. Delphi subjects its steering and suspension components to extreme temperature exposure and extended salt-spray testing to evaluate durability in demanding conditions. This bushing is intended for rear upper outer suspension service on Mercedes-Benz S-Class and CL-Class vehicles, including select Maybach variants.

This part cross-references Dorman - OE Solutions 521-485 for the same application. The Delphi TD1105W part number is a practical choice when replacing worn rear upper outer bushings on Mercedes-Benz S550, S600, and S63 AMG platforms where suspension geometry and bushing condition affect handling and tire wear.

What It Helps Address

• Rear suspension looseness or excess movement at the control arm
• Clunking or knocking from worn bushing material
• Uneven tire wear caused by suspension alignment instability
• Imprecise rear-end handling or reduced road feel
• Visible cracking, hardening, or deterioration of the original rubber bushing

Installation Notes and Tips

Install in the rear upper outer control arm position only. Because this is a press-fit bushing, proper removal and installation tools are recommended to avoid damage to the control arm or new bushing. Verify the vehicle application by year, model, and suspension position before ordering, especially on Mercedes-Benz S-Class, Maybach S-Class, and CL-Class variants.

Quality Assurance

Delphi applies OE-focused testing and dimensional analysis to support consistent replacement quality. The part is evaluated for temperature resistance and corrosion exposure as part of Delphi's suspension and steering validation process.
