Detailed Description

TRW JTC130 is engineered for BMW 528i, 525i, and 530i applications that use the front left lower rearward suspension position. This assembly combines the control arm and ball joint into one service part, helping restore suspension alignment and front-wheel control on the BMW 5 Series platform. The non-greaseable design supports a sealed service approach for routine replacement work.

This part cross-references MOOG Chassis Products RK80529 for the same application. The TRW JTC130 part number is also useful when verifying interchange references during suspension repair on BMW 528i, 525i, and 530i models.

What It Helps Address

• Front-end looseness or wandering during driving
• Clunking or knocking from the front suspension
• Uneven tire wear related to worn suspension geometry
• Steering response that feels less precise
• Excess play from a worn control arm or ball joint assembly

Installation Notes and Tips

Confirm the front left lower rearward position before ordering, since this assembly is position-specific. After installation, perform a professional wheel alignment to verify suspension angles and steering wheel centering. Inspect adjacent bushings, tie rods, and mounting points during service to ensure the repair addresses the full front suspension condition.

Quality Assurance

TRW is a recognized OE-focused chassis brand, and JTC130 is built for direct replacement use on the listed BMW applications. Verify fitment by year, model, and suspension position before installation.
