This suspension component is engineered for the BMW 740i, BMW 745e, BMW 750i, and BMW 750Li where the front left lower rearward control arm needs replacement. Dorman 527-097 is evaluated to help maintain proper suspension geometry and consistent road feel after service. The casting/forged control arm design, regular grade construction, and installed ball joint make it a practical OE replacement for worn or damaged front suspension hardware.

Common Problems This Part Can Help Solve

• Clunking or knocking from the front suspension
• Excessive play caused by worn ball joint or bushings
• Uneven tire wear related to suspension looseness
• Steering wander or reduced directional stability
• Vibration or imprecise handling from a damaged control arm assembly

Installation Notes and Tips

Verify vehicle fitment by year, make, model, and front left lower rearward position before installation. Because the ball joint is already installed, replacement focuses on removing the worn assembly and transferring the suspension back to proper alignment specifications after service. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
