Beck/Arnley Suspension Control Arm P/N:102-8311
Locate the rear wheel and control suspension geometry with the Beck/Arnley Suspension Control Arm 102-8258, a rear upper 2014-2018 Mazda 3 control arm engineered as a direct replacement for Original Equipment applications. Beck/Arnley focuses on foreign-nameplate coverage with special attention to form, fit, and function, sourced through a trusted global network so you can install with confidence.
This is an application-specific part for this vehicle. A worn control arm can show up as clunking over bumps or during turns and braking, loose or wandering steering, and uneven tire wear; if a failed rear upper arm is the cause, this replaces it. Control arms install as left/right pairs, so inspect and service both sides as needed. See the Buyer's Guide tab for engine-level fitment details.
