Detailed Description

This Dorman suspension ball joint is designed for BMW 325xi and BMW 330xi models from 2001 through 2005 in the front inner lower left position. The steel body, threaded design, and tapered stud support a direct replacement approach for the original equipment layout.

This part cross-references Beck/Arnley 101-7357 and MOOG Chassis Products K500348 for the same application.

Common Problems It Can Help Address

• Front suspension looseness or play at the lower control arm connection
• Clunking or knocking noises from the front suspension
• Uneven tire wear caused by worn ball joint movement
• Steering instability or imprecise front-end response
• Inspection failure related to excessive joint wear

Installation Notes and Tips

Verify the front inner lower left position before installation and confirm the tapered stud, threaded mounting style, and 12 mm wrench size match the vehicle. Inspect the surrounding suspension components, mounting points, and dust boot condition during service. Because this is a bolt-in style replacement, proper torque and alignment checks after installation are recommended.
