Replace a worn front left lower control arm, ball joint and bushings in one step on the 2010-2013 Mazda 3 or 2010-2013 Mazda 3 Sport with this Mazda 3 control arm from Dorman OE Solutions, part number 521-997. It is a control arm with ball joint for the front left lower position. This Dorman lower control arm is designed as a direct replacement for the original equipment on the listed applications. The ball joint and bushings come already installed, which saves time and labor. See the Buyer's Guide tab for full application details.

  • Trustworthy replacement: built to take the place of the original assembly on specific vehicle applications.
  • Complete repair: each assembly arrives with a pre-installed ball joint and bushings, saving time and labor.
  • Quality engineering: put through an industry-leading testing and evaluation process aimed at a smooth, stable ride, directional stability and predictable dynamics.
  • Durably designed: additional coatings provide rust and corrosion resistance.

The Dorman suspension control arm and ball joint assembly links the steering knuckle to the chassis. It lets the wheel travel up and down with the suspension while helping hold it in position and pivot for steering. Signs it may need replacing include clunking over bumps, loose or wandering steering, and uneven tire wear. If a worn arm, ball joint or bushing is the cause, this assembly replaces all three at once. It is sold individually for the front left lower position, and replacing both sides together is recommended. A wheel alignment is recommended after installation.

Frequently Asked Questions

Will this work as a 2010 Mazda 3 control arm?

Yes. It is listed for the 2010-2013 Mazda 3 and the 2010-2013 Mazda 3 Sport in the front left lower position.

What does a control arm with ball joint do?

It connects the steering knuckle to the chassis. This lets the wheel move up and down with the suspension while helping hold it in position and pivot for steering.

What comes pre-installed on this part?

The ball joint and bushings arrive already installed in the arm, so they do not have to be fitted separately. This saves time and labor during the repair.

What are signs a lower control arm may need replacing?

Common signs include clunking over bumps, loose or wandering steering, and uneven tire wear. Diagnose the cause first, since tie rods, struts and other parts can cause similar symptoms.

Is anything else needed for installation?

Consult the vehicle service information for the correct fasteners and whether the originals may be reused. A wheel alignment is recommended after installing a new control arm.
