Product Details
The Febi PROKIT line focuses on application-specific suspension components built around OE-style dimensions and fitment. This ball joint is specified for Mercedes-Benz front and front lower control arm locations, with the listed M14 x 1.5 outside thread and 20.2 mm cone size called out in the fitment notes. Part number 03668 is listed for a wide range of Mercedes-Benz sedans and coupes, including 300D, 300TD, 300SE, 300SEL, 380SE, 380SEL, 420SEL, 500SEC, 500SEL, 560SEC, and 560SEL applications.
This part cross-references Mercedes-Benz 116 333 09 27 for the same application. If you are replacing a worn Mercedes-Benz 300D front lower ball joint or servicing a 500SEL front suspension, verify the cone size and thread specifications against the original part before installation.
What It Helps Fix
- Front suspension looseness or play
- Clunking or knocking from the control arm area
- Uneven tire wear caused by worn ball joint geometry
- Steering instability or wandering on Mercedes-Benz front suspension systems
- Inspection failure from excessive joint movement
Installation Notes and Tips
Confirm the control arm type, stud thread diameter, thread pitch, and cone size before installation. This part is listed for front and front lower positions depending on the vehicle application, so match the exact fitment row for your Mercedes-Benz model and year. Inspect the surrounding suspension hardware and alignment settings after replacement. For Mercedes-Benz 300SE, 300SEL, 350SD, and 350SDL applications, review the fitment notes carefully because some listings are shown without a specific position.
