Let’s keep it clear—this isn’t just a “small bearing” for your Chery A5. It’s the rear wheel’s “load-bearing & smooth-rotation core”: a precision-sealed component tucked inside the A5’s rear wheel hub, sitting between the rear axle and the wheel itself. Think of it as the “hidden connector” that does two big jobs: it supports the entire weight of the car’s rear end (so the wheel doesn’t sag) and lets the rear wheel spin smoothly with almost no friction (so you drive quietly and efficiently). Without it, your A5’s rear wheel would grind, shake, or even lock up—making every drive noisy, unstable, and risky.
This rear wheel hub bearing is exclusively made for the Chery A5—always confirm your vehicle’s VIN to be sure! It’s tailored to fit perfectly: its inner ring locks tightly to the A5’s rear axle (no slipping), its outer ring fits snugly into the rear wheel hub (no wobbling), and its sealed design matches the A5’s rear suspension setup (keeps out dirt and water). Grab a generic bearing? You’ll run into trouble: it won’t handle the A5’s weight (bends or cracks), lets dirt in (rusts fast), or makes the wheel shake—all leading to uneven tire wear and even loss of control.
It’s a workhorse for your A5’s rear end—here are 3 non-negotiable things it does:
Bear the rear weight: It holds up the entire back half of the A5, transferring the car’s weight from the rear axle to the wheel. Without this support, the rear wheel would collapse or tilt, ruining tire alignment.
Reduce friction: Inside the bearing, small metal balls (or rollers) roll between two rings (inner and outer), cutting down friction as the wheel spins. This means less energy wasted—so your A5 drives smoother and uses fuel more efficiently.
Stabilize the wheel: It keeps the rear wheel centered on the axle, preventing side-to-side wobble. Wobbling wheels cause shaky steering, loud road noise, and uneven tire wear (you’ll replace tires twice as often).

This A21-3301210 rear wheel hub bearing only works for the Chery A5—wrong fit = rear wheel failure:
Installing this bearing needs precision tools and axle knowledge—DIY will ruin your A5’s rear wheel:
Prep the rear wheel: Techs lift the A5, remove the rear wheel, brake caliper, and rear hub assembly (uses a press tool to avoid damaging parts).
Remove old bearing: They press the old bearing out of the hub (forceful prying bends the hub) and clean the hub’s inner surface (removes rust or debris).
Install the new bearing: They press A21-3301210 into the hub (to exact Chery torque specs—too loose = wobble; too tight = friction), then reattach the hub to the rear axle.
Reassemble & test: They put the brake caliper and wheel back on, lower the car, and test-drive to check for rear-end noise, wobble, or uneven braking (ensures the bearing works right).
Listen for : If you hear a low hum, grinding, or rumbling from the rear while driving, the bearing is wearing out—get it checked fast (ignoring it leads to wheel lock-up).
Check for wheel play: Jack up the rear, grab the wheel top and bottom, and wiggle it. If there’s more than 1mm of play, the bearing is loose (needs replacement).
Keep it clean: Avoid driving through deep mud or standing water—if the seal cracks, dirt gets in and ruins the bearing (rinse the rear wheels gently after off-road drives).
Don’t overload the A5: Too much weight in the trunk or rear seats strains the bearing (shortens its life—stick to the A5’s maximum load limit).

Exclusive to Chery A5 (confirm via VIN), this sealed bearing fits the rear wheel hub—linking the rear axle and wheel. It supports the A5’s rear weight, cuts friction for smooth wheel spin, and stops wobble or sudden lock-up.
It won’t fit other Chery models (e.g., QQ, Tiggo 3), non-Chery cars, or A5’s front wheels. Install by certified techs; maintain by watching for rear hum/grinding (wear signs) and wheel play, plus avoiding overloading. Only the original ensures long-term durability and safety.
