First, let’s define its core role: the
Chery S5 New Front Wheel Hub 3103010U1510XA isn’t just a “wheel-mounting part”—it’s the
critical “bridge” between the S5’s front wheel, suspension, and drivetrain. Think of it as a compact, integrated unit bolted to the front suspension
knuckle, designed to hold the front wheel in place while enabling two key actions: smooth wheel rotation (for driving) and flexible steering (for turning). Its main jobs? To support the entire front-end weight of the S5, transfer power from the drivetrain to the front wheel (if the S5 is front-wheel drive), reduce friction during wheel spin (via built-in bearings), and keep the wheel aligned with the steering system. Without it, the front wheel would wobble, steer poorly, or even detach—making driving impossible.
This front wheel hub is
exclusively engineered for the Chery S5’s front axle—always confirm with your vehicle’s VIN! It’s tailored to fit perfectly: its bolt pattern matches the S5’s front wheel and suspension knuckle (no forced drilling), its bearing size aligns with the S5’s drivetrain torque (avoids premature wear), and its overall thickness matches the front axle’s spacing (ensures proper wheel alignment). A generic hub? You’ll face issues: it’ll have mismatched bolt holes (can’t mount the wheel), weak bearings (fails at high speeds), or incorrect thickness (throws off steering alignment)—all major safety hazards.
Its role is foundational to front-end performance and safety—here are 4 key tasks it performs for your S5:
Supports front-end weight: It bears the full weight of the S5’s front half (including the engine, if front-mounted) and distributes it evenly to the front wheel. This keeps the wheel stable, even over potholes or rough roads.
Transfers drivetrain power (FWD S5 variants): For front-wheel-drive S5 models, the hub has a splined center that connects to the driveshaft. It spins with the driveshaft, turning the front wheel and propelling the car forward.
Enables smooth rotation: Built-in precision bearings let the hub (and attached wheel) spin freely with minimal friction. This reduces energy loss (boosts fuel efficiency) and prevents overheating during long drives.
Syncs with steering: It’s mounted to the suspension knuckle, which links to the S5’s steering rack. When you turn the steering wheel, the knuckle (and hub) pivots—turning the front wheel in the desired direction without compromising wheel stability.

This 3103010U1510XA front wheel hub is only for the Chery S5’s front axle—wrong fit = front-end failure:
Fits These Models: All Chery S5 variants (matches front suspension knuckle design, wheel bolt pattern, and drivetrain specs—confirm via VIN). Works for both front-wheel-drive (FWD) and all-wheel-drive (AWD) S5 models (FWD hubs have drivetrain splines; AWD hubs match front axle spacing).
Won’t Fit These:
Chery S5 rear axle: Rear hubs have different bolt patterns and no steering integration—can’t mount to rear suspension.
Other Chery models (e.g., A13, Tiggo7 Pro): Their front suspension knuckles, wheel sizes, and bearing specs differ—hub won’t align or function.
Non-Chery vehicles: Even if bolt holes “match,” the hub’s thickness and bearing capacity are incompatible—causes steering drift or wheel failure.
Installing this hub requires specialized tools and torque calibration—DIY risks fatal accidents:
Remove old hub: Technicians lift the S5, remove the front wheel, brake caliper, and rotor, then unbolt the old hub from the suspension knuckle. They disconnect the driveshaft (FWD models) carefully to avoid damage.
Prep and mount new hub: They clean the knuckle’s mounting surface, apply anti-seize compound (prevents rust), then bolt 3103010U1510XA to the knuckle using a torque wrench (follows Chery’s exact torque specs—too loose = wobble; too tight = bearing damage).
Reassemble and align: They reattach the driveshaft (FWD), rotor, and brake caliper, then remount the wheel. Finally, they perform a front-end alignment to ensure the hub/wheel are correctly angled (prevents uneven tire wear and steering drift).
Test drive: They take the S5 for a short drive to check for vibrations, abnormal noises, or steering pull—confirming the hub works smoothly.
Check the dust seal quarterly: Inspect for cracks or damage (a broken seal lets dirt in—ruins bearings fast). Replace the seal if it’s worn.
Monitor hub temperature after driving: After a 30-minute drive, touch the hub (carefully—avoid hot parts). If it’s excessively hot (too hot to hold), the bearing is failing—have it replaced immediately.
Avoid potholes/curbs: Hard impacts bend the hub or damage bearings (even small dents cause wobble or noise). Drive carefully over rough roads.
Replace every 80,000–100,000 km: Even if it works, bearings wear out over time. Proactive replacement avoids sudden failure on the road.

Exclusive to Chery S5’s front axle (confirm via VIN), this hub links the front wheel, suspension, and drivetrain. It supports the S5’s front weight (stabilizes wheels on rough roads), transfers power to the front wheel (for FWD models), uses built-in bearings for smooth, low-friction rotation (boosts fuel efficiency), and syncs with steering for accurate turns.
It fits perfectly (matching bolt patterns/bearing specs); generic hubs cause wobble or steering issues. Install by certified techs; maintain by checking seals and replacing every 80,000–100,000 km. Only the original ensures safety.
