Delphi TC3004 Suspension Control Arm and Ball Joint Assembly - Front Left Upper

OE-Style Front Left Upper Control Arm

Delphi TC3004 is a front left upper suspension control arm and ball joint assembly built for Land Rover LR3 applications. It uses stamped steel construction, a rubber bushing, and a pre-greased ball joint to support precise front suspension movement and consistent steering response.

Fits 2005-2008 Land Rover LR3, front left upper. Fits 2009 Land Rover LR3, front left upper, without B6 level armouring.

Key Features

• Part number TC3004
• Front left upper suspension control arm and ball joint assembly
• Stamped steel control arm construction with black finish
• Press-in ball joint with threaded stud
• Pre-greased design; no grease fitting included
• Rubber bushing material for standard replacement service
• Non-adjustable, non-greaseable design

Detailed Description

Delphi TC3004 is engineered as a standard replacement suspension control arm for the front left upper position on the Land Rover LR3. The stamped steel arm and press-in ball joint are matched to OE-style dimensions and materials to support proper suspension geometry, while the rubber bushing helps isolate road vibration. Delphi applies dimensional and material analysis to improve part-to-vehicle fit, and the assembly is tested for temperature extremes and salt-spray exposure to reflect demanding underbody conditions. This part cross-references MOOG Chassis Products RK622629 for the same application.

Common Problems This Part Can Address

• Excessive front-end looseness or wandering on LR3 suspension systems
• Clunking or knocking from the front left upper control arm area
• Uneven tire wear related to worn suspension joints or bushings
• Steering instability caused by play in the upper control arm assembly
• Suspension noise from deteriorated rubber bushings or ball joint wear

Installation Notes and Tips

Verify vehicle fitment by year and note that the 2009 Land Rover LR3 application is for vehicles without B6 level armouring. Replace the assembly at the front left upper position only. Because the ball joint is press-in and the arm is non-adjustable, proper suspension inspection and alignment checks are recommended after installation.

Quality Assurance

Delphi uses OE-focused engineering, dimensional checks, and material analysis to support consistent aftermarket fitment. The TC3004 is exposed to extreme temperature testing and extended salt-spray testing to evaluate durability in harsh service conditions.
