First off, let’s keep it simple: the
Chery A5 Front Left Control Arm A21-2909010BB isn’t just a random metal bar—it’s the “core link” between your A5’s front left wheel and the car’s frame. Think of it as the part that keeps your wheel steady, pointed the
right way, and connected to the rest of the suspension. It’s not just for show: this control arm lets your wheel move up and down over bumps (so you get a smooth ride) while stopping it from wobbling side-to-side when you turn or hit the brakes. Without a working front left control arm, your A5 will feel “loose” when steering, pull to the right on straight roads, and wear out your front left tire super fast—total safety risks, especially at high speeds.
This front left control arm is exclusively for Chery A5 models built on the A21 platform—mostly A5 variants from 2006 to 2012 (always double-check your car’s VIN or owner’s manual to confirm!). It’s engineered to match the A21 platform’s front suspension exactly: the mounting holes line up perfectly with the frame and wheel hub, the length is calibrated to keep your wheel at the right angle (called “camber” and “toe”), and the bushings/ball joint are tuned to handle the A5’s 1.6L/1.8L/2.0L engine weight. Slap on a generic control arm? You’ll run into chaos: uneven tire wear (you’ll need new tires in months), weird steering noises (like clunks when turning), or even a loose wheel—all things that can lead to accidents.

This A21-2909010BB control arm only works with A21-platform Chery A5s—using the wrong one is a waste of money and a safety hazard. Here’s the deal:
Fits These Models: Chery A5 (A21 platform) 2006–2012. Works with all trims (Comfort, Luxury) and engine types (1.6L, 1.8L, 2.0L)—since all A21 A5s share the same front suspension design.
Won’t Fit These:
Other Chery models (e.g., A3, Arrizo 5): Their front suspensions are smaller/lighter—this control arm is too long and heavy, leading to stiff steering.
Newer Chery cars (e.g., Tiggo 5, Arrizo 7): These use updated suspension systems with different control arm shapes—this A21 arm won’t mount.
Non-Chery vehicles: Even if it “looks similar,” the mounting holes and ball joint size are wrong—you’ll get loose parts and bad alignment.
System Compatibility: Must be paired with Chery’s original front left ball joint (if it’s a separate part) and bushings. Aftermarket ball joints are often too loose or too tight—causing steering play or stiffness. It also works with the A5’s original front stabilizer bar (no extra adapters needed).
This isn’t a DIY job—installing a control arm requires precise wheel alignment, and messing it up will ruin your tires and steering. Only take your A5 to a Chery 4S shop or a mechanic who knows A21 platforms. Here’s why:
Wheel Alignment: After installing the control arm, techs use computer tools to adjust camber, toe, and caster (the angles that keep your wheel straight). Without this, your A5 will pull to the right and wear tires unevenly.
Proper Torque: The control arm’s bolts need to be tightened to Chery’s exact specs (usually 50–65 N·m). Too loose, and the arm rattles; too tight, and the bolts snap (ruining the frame).
Ball Joint Check: Techs will also inspect the ball joint (if it’s part of the arm) to make sure it’s not too loose—loose ball joints cause steering play and can break while driving.

Summary
The original A21-2909010BB actually passes tests for handling curbs, potholes, and even crazy temperatures—hot or cold. It keeps your wheel alignment spot-on, your ride nice and smooth, and your A5 safe to drive.
Bottom line, the Chery A5 Front Left Control Arm A21-2909010BB is the “backbone of your front suspension.” It keeps your wheel nice and steady, your ride smooth, and your A5 safe. Stick with the original part, have pros install it, and you’ll never stress over loose steering or uneven tire wear again.
