Control arm kits for the Toyota Matrix start at $216.95 and AutoBuffy stocks 2 options from Mevotech Original Grade and Mevotech Supreme. A control arm connects the wheel hub to the frame, keeping your wheels properly aligned through every bump and turn. When the arm, bushings, or ball joint wear out, handling deteriorates and tire wear accelerates — making replacement critical for safety.
The main decisions are whether to replace just the arm, the full kit with pre-installed ball joint and bushings, or the upper versus lower position. A complete kit costs more upfront but eliminates the need to press in separate components and ensures all wear points are addressed at the same time.
| Option | Best for | What you get |
|---|---|---|
| Lower Control Arm Kit | Most common replacement; lower arms carry the most load and wear fastest | Lower arm with ball joint and bushings pre-installed, ready to bolt on |
| Upper Control Arm Kit | Vehicles with double-wishbone suspension where upper arms are also worn | Upper arm with ball joint and bushings, restores full geometry correction |
| Complete Front Kit (Upper + Lower, Both Sides) | High-mileage vehicles with worn components on both sides | Full set of arms, ball joints, and bushings; maximizes alignment stability |
| OE-Replacement Grade | Daily drivers needing factory fit and durability at a reasonable price | Stamped or cast steel arm matching original specs with standard rubber bushings |
| Heavy-Duty / Performance Grade | Trucks, tow vehicles, or performance builds needing extra rigidity | Reinforced arm with upgraded polyurethane bushings and higher-rated ball joint |
Raise and safely support the Toyota Matrix, then remove the wheel to access the control arm mounting bolts and ball joint stud. Disconnect the ball joint from the steering knuckle using a separator tool, unbolt the arm from the frame, and reverse the process with the new kit. Torque all fasteners with the suspension at ride height, not full droop, then schedule an alignment before driving.
