Key Features

  • Steel construction for suspension service applications.
  • Pressed mounting type for OE-style installation.
  • Tapered stud with 16 mm thread diameter.
  • Rubber dust boot helps protect the joint from contamination.
  • Standard-grade replacement for specific GM and Saab platforms.

Detailed Description

MAS Chassis BJ92145 is engineered and tested as a replacement suspension ball joint for the front lower position on a range of GM and Saab vehicles, including Chevrolet Trailblazer, GMC Envoy, and Saab 9-7x applications. The pressed-in design, polymer bearing material, and tapered stud support stable suspension articulation where the original joint has worn or loosened. This part cross-references Monroe Shocks & Struts (e.g., K6663, TC1845) for the same application.

What It Helps Fix

  • Clunking or popping noises from worn suspension joints.
  • Excessive play in the lower suspension connection.
  • Uneven tire wear caused by loosened joint movement.
  • Steering looseness related to front suspension wear.
  • Restoration of proper suspension geometry after joint failure.

Installation Notes and Tips

Press-fit installation is required, so the old joint must be removed from the control arm before the new part is installed. Verify the front lower application, stud thread size, and housing press-fit diameter before service. Because this part is not greaseable and does not include a cotter pin hole or castle nut, confirm the fastener and service procedure for the vehicle before installation.

Quality Assurance

MAS Chassis states that this ball joint is precision-engineered and rigorously tested for reliable OE replacement performance on the listed applications.

This part fits 50 vehicles
Always verify fitment with your vehicle's VIN if unsure. Submodel & trim restrictions may apply.
