Detailed Description
Delphi TC7054 is engineered for the front left lower rearward suspension position on select Audi Q7, Q8, SQ7, SQ8, RS Q8, A8 Quattro, e-tron models, and Porsche Cayenne applications. Delphi applies OE-focused dimensional and material analysis to help match aftermarket fit and function to the original part, while the assembly is tested across extreme temperature ranges and salt-spray exposure for durability. This part cross-references MOOG Chassis Products RK623727 for the same application.
What This Part Helps Address
- Clunking or knocking from the front suspension
- Excessive play in the lower control arm assembly
- Uneven tire wear caused by worn suspension joints or bushings
- Steering wander or reduced front-end stability
- Visible cracking, separation, or wear in the original control arm bushings
Installation Notes
Verify the vehicle position before installation: front left lower rearward. This assembly uses a press-in ball joint and threaded stud, so proper suspension service tools and torque procedures are required. Confirm fitment by year, make, model, and position before ordering. Part number TC7054 is also listed under OE and aftermarket references for select applications.
Quality Assurance
Delphi subjects steering and suspension components to temperature testing below -40 degrees C and above 120 degrees C, along with 720 hours of salt spray exposure. The brand also uses dimensional and material analysis to support OE-level compatibility between original and replacement parts.
