Bring a fresh ball joint and bushings to your roadster's front suspension with the Dorman control arm 522-957 from Dorman OE Solutions. This front left upper arm is a direct replacement for the original equipment on the 1991-1997 Mazda Miata. It lets you swap out worn Miata A-arms for a replacement assembly with the joint and bushings already in place.
The arm connects the steering knuckle to the chassis. It lets the wheel travel up and down with the suspension, and the ball joint provides the pivot for steering. Dorman put it through an industry-leading evaluation process aimed at a smooth ride, directional stability and predictable dynamics.
- Trustworthy replacement: takes the place of the original assembly on the listed applications.
- Pre-installed components: the ball joint and bushings come already fitted, saving time and labor.
- Quality engineering: tested by Dorman, with the goal of a smooth, stable and safe ride.
- Durably designed: additional coatings help resist rust and corrosion.
Signs this arm may need replacing include:
- clunking or knocking over bumps
- loose or wandering steering
- uneven tire wear
- cracked or torn bushings
If a worn arm or ball joint is the cause, this assembly replaces both in one piece.
This listing is for the front left upper position and is sold individually. Replacing the right side at the same time is recommended for balanced handling, and a wheel alignment check after installation is advised.
