• Black cataphoresis finish for added corrosion resistance
• Natural rubber bushing material with rubber bearing type
• Straight, non-adjustable design
• Rear lower rearward position for the listed applications
• Ball joint not included
• Mounting hardware not included
• Pre-greased: No

Detailed Description

Delphi TC3221 is engineered as an OE-style suspension control arm for rear suspension service on the Audi Q7, Porsche Cayenne, and Volkswagen Touareg. Delphi applies dimensional and material analysis to match OE fit and material characteristics, while testing components across extreme temperatures and extended salt spray exposure to evaluate durability in demanding conditions. The result is a standard replacement control arm that supports rear suspension alignment and consistent handling response in the specified rear lower rearward position.

This part cross-references Beck/Arnley 102-6138 and Dorman - OE Solutions 522-989 for the same application. Delphi TC3221 is also associated with OE and aftermarket interchange references used on these platforms.

What It Helps Address

• Rear suspension looseness or clunking from worn control arm bushings
• Uneven tire wear caused by rear alignment movement
• Excessive rear-end play during braking or cornering
• Corrosion-related replacement needs on aging suspension components
• Restoring rear suspension geometry on Audi Q7, Porsche Cayenne, and Volkswagen Touareg models

Installation Notes

Verify the rear lower rearward position before installation and compare the original arm length, mounting points, and bushing layout to the replacement part. Because mounting hardware is not included, reuse or replace fasteners as required by the vehicle service procedure. A professional alignment is recommended after suspension component replacement to confirm correct rear geometry.

Quality Assurance

Delphi backs its aftermarket steering and suspension portfolio with OE-focused engineering and validation. TC3221 is built using OE-oriented dimensional checks and material analysis, with durability testing that includes extreme temperature exposure and salt spray evaluation to help confirm long-term service performance.
