What it is: The A21-3401330BB is basically the Outer Tie Rod End – a core part of Chery A5’s steering system.
Key connection: Links the steering tie rod and steering knuckle; uses a ball joint to pass steering force and let wheels swing.
Critical role: In Chery A5’s rack-and-pinion steering system, the A21-3401330BB directly affects wheel steering angle and toe adjustment – it’s what keeps the steering wheel “on target.”
Main jobs:
Transmits steering force: When cornering at high speed, the A21-3401330BB’s ball joint swings to turn wheels smoothly (from the steering rack’s lateral movement).
Adjusts toe: Changing the outer tie rod’s length (via A21-3401330BB) fixes wheel toe, preventing uneven tire wear or car pulling.
Reduces vibration: Grease inside the A21-3401330BB’s ball joint + outer dust cover cuts road bump impact, extending part life.
Part number breakdown:
Material & process: Forged high-strength alloy steel; A21-3401330BB’s ball joint surface is quenched (more wear-resistant than regular cast parts).
Installation size: Thread M14×1.5 (minor differences for some models); ball joint diameter ~22mm (fits Chery A5’s steering knuckle).
Fit models: Chery A5 (2006-2010), Qiyun 3, E5 (all A21-platform models).
Heads up: Only works with rack-and-pinion steering systems – not recirculating ball systems (common in commercial vehicles).
Clunking when turning: Likely worn ball joint or dried grease in the A21-3401330BB.
Loose steering wheel (“play”): Feels wobbly when turning; severe cases cause straight-line pulling.
Uneven tire wear: Inner/outer tire wears faster – usually from loose A21-3401330BB (messes up wheel toe).
Visual check: Look for cracks in the A21-3401330BB’s dust cover or oil leaks on the ball joint; oil stains mean broken seals.
Wobble test: Use a crowbar to pry the wheel – no obvious play should come from the A21-3401330BB (normal = no wobble).
Toe measurement: Use a wheel alignment machine; if toe deviates over ±0.5°, check if the A21-3401330BB is damaged.
Replacement cycle: No fixed time – check the A21-3401330BB every 40,000-60,000 km, or right when faults appear.
Extra tip: Shorten inspection intervals if you drive on bumpy roads often.
Replacement notes:
Use proper tools (e.g., wrench, ball joint separator).
After installing the new A21-3401330BB, get a wheel alignment (to fix toe).
Part choice: Genuine A21-3401330BB is more reliable; trusted aftermarket parts work too – just confirm model match!

Fits tons of cars, no hassleThis A21-3401330BB is made for the A21 platform, so it fits Chery A5 (2006-2010) perfectly. Plus, it works for Qiyun 3 and E5 too—same platform, no need to tweak the mounting holes. And it’s strictly for rack-and-pinion steering (the usual type in passenger cars), so you won’t mix it up with wrong parts.
Super tough, hard to break
The main part’s forged high-strength alloy steel—it stands up to pulling and bending way better than regular steel, even when the steering pushes hard sideways.
The ball joint’s surface is quenched, so it’s harder and more wear-resistant. Lasts over 30% longer than cheap cast parts, y’know?
It comes with a dust cover and grease inside—keeps dirt and rain out, stops the ball joint from drying out and wearing down. Makes the A21-3401330BB last way longer.
Works spot-on, keeps you safe
It directly controls the wheel’s steering angle and toe setting. The A21-3401330BB’s ball joint swings smoothly, so steering force gets passed through with no lag. Less “play” in the steering wheel, and no pulling when driving straight.
You can adjust the outer tie rod length (thanks to this A21-3401330BB) to fix the toe. Stops the tire’s inner or outer side from wearing down too fast—saves you money on new tires.
Easy to maintain, flexible to choose
Checking it is a breeze: no taking it apart. Just look at the dust cover (cracked? leaking oil?) or use a crowbar to wiggle the wheel—if the A21-3401330BB doesn’t shake, it’s good.
Replacing it’s simple too: just use regular wrenches and a ball joint separator. After putting in the new A21-3401330BB, just do a wheel alignment to fix the toe—no fancy tweaks needed.
You can pick the genuine A21-3401330BB for reliability, or a good aftermarket one if you want a better deal. Either way, just make sure the model matches!

All in all, this A21-3401330BB? It’s perfect for Chery A5, Qiyun 3, and E5—they’re all on the same platform, y’know? It’s totally made for rack-and-pinion steering, so no stress about grabbing the wrong part.
The main part’s forged alloy steel, and the ball joint’s even been quenched. Plus it has a dust cover and grease inside—super tough, and it lasts way longer than cheap stuff.
Using it’s no hassle either: no loose steering wheel, no pulling when you drive straight. And you can tweak the toe to keep the tires from wearing unevenly—saves you both trouble and money.
Maintenance is even easier! Just glance at it or wiggle the wheel real quick to see if it’s good. Swap it out with regular wrenches, do an alignment after—and you’re good to go. You can pick genuine parts or solid aftermarket ones—either works, just make sure the model’s right!
