Bring the Delphi control arm TC7656 to your rebuild to help maintain proper wheel location and a stable, controlled ride. This rear upper suspension control arm links the knuckle to the chassis, locates the wheel through its travel, and pivots on a machined ball stud for smooth articulation. It drops in as a direct-fit replacement for many vehicles, among them the 1997-2001 Honda CR-V, 1993-1997 Honda Civic Del Sol and 1988-1991 Honda CRX — see the "Vehicles it fits" section for the full list.
Delphi builds this arm with its OE engineering, validated with dimensional and material analysis for close OE compatibility, and tested to the extreme: below -40 °C to over 120 °C and 720 hours of salt spray.
- Verified integrity: 100% crack detection and ultrasonic flaw detection help ensure materials match OE specifications.
- Robot-welded: consistent welds for repeatable quality.
- Precision ball stud: machined to micron tolerances for durable, smooth joint operation.
- Anti-corrosion protection: applied to each part for corrosion prevention and enhanced appearance.
Worn control-arm bushings or a loose ball stud can cause clunking over bumps, uneven tire wear, and vague steering; if the original rear upper arm is the cause, this replaces it.
