Keep the rear wheel precisely located with the Beck/Arnley Suspension Control Arm 102-8383, the Q50 control arm designed as a direct replacement for Original Equipment (OE) applications. This rear lower forward arm pivots with suspension travel to locate the wheel and carry a suspension bushing, and it drops into the listed Infiniti applications: 2011-2013 M37, 2011-2013 M56, 2012-2013 M35H, 2014-2024 Q50, 2017-2022 Q60, 2014-2019 Q70, and 2015-2019 Q70L. See the Buyer's Guide tab for the full application details.
- OE-matched: built to match OE form, fit and function for the listed foreign-nameplate applications.
- Without ball joint: this control arm comes without a ball joint, matching the OE design.
- Durable build: steel, iron, or aluminum construction for durability and rust/corrosion resistance.
- Hardware: new hardware and bushings included where applicable.
Clunking or knocking from the rear suspension, wandering, uneven tire wear, and alignment that won't hold can be signs the control arm or its bushing is worn. If a failed rear lower forward arm is the cause, this application-specific unit replaces it.
