The Front Wheel Hub 3103100P3060 is a total workhorse part for JAC T8 pickup trucks—it’s the key component that connects the front wheel to the truck’s axle. It supports the whole front-end weight (including you, your passengers, and whatever cargo you’re hauling), sends power to the wheels (for 4WD models), and lets the front wheels turn smoothly. Think of it as the “bridge” between your T8’s chassis and front wheels—without a strong, working hub, you’ll get wobbly steering, weird noises, or even unsafe driving conditions.
This hub is made specifically for 2018–current JAC T8 models. It fits both 2WD and 4WD versions, plus every trim level (Comfort, Elite, Luxury) and both engine types: the 2.0T diesel (4DB2-1D1) and 2.0T gasoline (4GA3-3D/4D). This isn’t a one-size-fits-all generic part—every size, hole, and component is tuned to fit the T8’s
front axle and steering system perfectly. No guesswork, no modifications needed.
This front wheel hub isn’t just for “holding the wheel on”—it has 4 critical jobs that keep your T8 driving safely and smoothly, especially for pickup tasks like hauling loads or light off-roading:
Supports the front-end weight: It’s made to handle the T8’s front weight—up to 650kg per wheel, even when the truck bed is packed with cargo. The hub’s tough structure won’t bend or break, even if you run over potholes or drive on bumpy dirt roads.
Sends power to wheels (for 4WD models): On 4WD T8s, the hub hooks up to the front axle’s half-shaft, sending engine power straight to the front wheels. This lets you flip to 4WD on slippery or bumpy ground—no power loss, no slipping.
Lets you steer smoothly: It works with the T8’s steering system—like the tie rods and steering
knuckle—to let the front wheels turn freely. The built-in bearings cut down on friction, so you won’t have to fight with stiff steering, even when parking or making tight turns.
Feeds info to safety systems: Most versions have a built-in ABS (Anti-Lock Braking System) tone ring on the back. This ring sends real-time wheel speed info to the T8’s ABS ECU. If you slam on the brakes, ABS uses this data to stop the wheels from locking up, so you stay in control.

This hub only works for JAC T8s—it won’t fit other trucks, not even other JAC models. Here’s exactly what it works with (and what it doesn’t):
Vehicles it FITS: 2018–current JAC T8s (both 2WD and 4WD, every trim level: Comfort, Elite, Luxury). It works for both the 2.0T diesel (4DB2-1D1) and 2.0T gasoline (4GA3-3D/4D) engines.
Vehicles it WON’T fit:
JAC T6 pickups—they have different axle sizes and bolt patterns, so the hub won’t line up.
Non-JAC trucks (like the Great Wall Wingle or Maxus T60)—their hub dimensions don’t match the T8’s, so it’ll be a bad fit.
JAC passenger cars (e.g., the Refine S5)—they’re too light to handle the T8’s load needs, so the hub is overkill and won’t work.
What it needs to pair with: It has to work with the T8’s original front wheel studs (look for part numbers that match 3103110P3000) and ABS sensor. Aftermarket studs or sensors might not play nice with the hub’s tone ring—and that can cause the ABS system to fail.
Trying to install this hub yourself is risky—only JAC-authorized techs (at 4S shops or certified repair centers) should handle this work. Here’s why:
Bearing preload needs to be perfect: The built-in bearings need exact “preload” (that’s just a fancy word for the
right tightness). If it’s too loose, the hub will wobble when you drive; too tight, and the bearings will overheat and fail fast. Techs use special tools to set the preload to JAC’s exact specs (0.05–0.1mm axial play)—you can’t do that with basic tools at home.
ABS alignment can’t be off: The tone ring on the hub has to line up perfectly with the ABS sensor—there needs to be a tiny 0.5–1mm gap between them. If they’re even a little misaligned, the ABS system might stop working, or it’ll trigger annoying false warnings on your dashboard.
Torque on the bolts matters: The hub’s mounting bolts need to be tightened to 85–90 N·m, and you have to do it in a crisscross pattern (like tightening a tire). Too loose, and the hub could come loose while you’re driving (super dangerous); too tight, and you might crack the axle—which is a way more expensive fix.

Summary
At the end of the day, the Front Wheel Hub 3103100P3060 is basically the unsung star of your JAC T8’s front end. It keeps your steering feeling nice and smooth, makes sure your ABS works like it’s supposed to, and keeps your truck safe—even when you’ve got a full load in the truck bed or you’re out driving off-road. Stick to the original part, have the pros install it, and your T8’s front end will stay reliable for years on end.
