The Delphi TC7901 suspension control arm is an OE-style replacement built for rear left upper suspension service on select Buick and Saab applications. It uses steel construction with a forged/cast design, rubber bushings, and a cataphoresis finish to support consistent fit and corrosion resistance.

Key Features

• Steel control arm with casting/forged construction
• Rear left upper position for specific Buick and Saab fitments
• Rubber bushings included; ball joint not included
• Black finish with cataphoresis coating
• No grease fitting and no mounting hardware included
• Regular-grade replacement part with non-adjustable design

Detailed Description

Delphi TC7901 is engineered for rear left upper suspension replacement where OE fit and material consistency matter. Delphi applies dimensional and material analysis to help match the original part profile, and the control arm is tested across extreme temperature ranges and salt-spray exposure to support durability in demanding road conditions. This part cross-references Dorman - OE Solutions 524-215 for the same application.

Compatible With 2010-2012 Buick LaCrosse, rear left upper; 2011-2012 Buick Regal, rear left upper; 2010-2011 Saab 9-5, rear left upper; and 2010 Buick Allure, rear left upper. The Delphi TC7901 is a direct-fit suspension control arm for these listed applications and is a practical choice when replacing worn rear suspension components on Buick LaCrosse, Buick Regal, Saab 9-5, or Buick Allure models.

What This Part Helps Address

• Rear suspension looseness or instability
• Clunking or knocking from worn control arm bushings
• Uneven tire wear caused by suspension wear
• Excessive rear-end movement over bumps
• Alignment issues related to worn rear control arm components

Installation Notes and Tips

Verify rear left upper position and vehicle application before installation. Inspect adjacent suspension bushings and mounting points for wear or damage, and confirm alignment after replacement. Because mounting hardware is not included, reuse or source the correct hardware as needed for the vehicle.

Quality Assurance

Delphi draws on OE engineering experience and subjects this control arm to temperature and corrosion testing to help maintain fit and durability. The TC7901 is built to align with OE-style dimensional and material requirements for the listed Buick and Saab applications.
