Detailed Description

Delphi TC3313 is a front left lower control arm assembly for Mini Cooper suspension service. It uses a stamped steel arm with a rubber bushing and a bolt-in, threaded ball joint design. The assembly is pre-greased and is not greaseable, with no grease fitting included. Delphi applies OE-based dimensional and material analysis to support fit and function across the aftermarket and subjects parts to temperature and salt-spray testing for durability validation. This part cross-references MOOG Chassis Products RK621263 for the same application.

Common Repair Applications

• Front-end clunking or looseness from a worn lower control arm assembly
• Steering wander caused by play in the ball joint or bushing
• Uneven tire wear related to front suspension wear
• Noise over bumps from deteriorated suspension joints
• Restoring front left lower suspension geometry on a Mini Cooper

Installation Notes and Tips

Verify the vehicle is a 2007-2015 Mini Cooper with the front left lower application and bushing note before ordering. Inspect adjacent suspension components, alignment settings, and mounting points during replacement. Because this assembly is pre-greased and not greaseable, no service fitting is provided.

Quality Assurance

Delphi uses OE-oriented engineering, dimensional checks, and material analysis to support compatibility with the original suspension layout. The part is also tested for extreme temperature exposure and salt-spray resistance as part of Delphi’s validation process.
