Free Wheel Hubs

About Hulk 4x4 Free Wheel Hubs

Hulk 4x4 free wheel hubs are replacement hubs for part-time 4WDs, covering popular Toyota, Nissan, Mitsubishi, Isuzu, Holden, Suzuki and Jeep models. Each hub is listed by vehicle and model code, and many listings include the bolt count, PCD and spline count so you can confirm fitment before ordering.

• Replacement free wheel hubs: swap out worn, slipping or seized hubs so your 4WD engages properly again.
• Manual locking hub upgrade: a heavy-duty manual locking hub that replaces factory automatic hubs on the Isuzu D-MAX, MU-X and Holden Rodeo, Colorado and Jackaroo.
• Model-specific fitment: hubs are matched to the model code, bolt pattern, PCD and spline count of your front axle.

Find the Right Free Wheel Hub for Your 4WD

Start with your vehicle's make and model code, then check the bolt count, PCD and spline count in the product listing against your existing hub. If your current hubs are slipping, grinding or won't lock in, a replacement free wheel hub will help get drive back to your front wheels when you need it.

Keep Your 4WD Ready to Engage

Free wheel hubs are a small part that decides whether your 4WD actually drives through the front wheels when the track gets tough. Replace worn hubs before your next trip, and see the rest of our underbody upgrades, including brake conversion kits and stainless steel exhaust kits.

Free Wheel Hub FAQs

What are free wheel hubs?

On part-time 4WDs, free wheel hubs disconnect the front wheels from the front axle when you're driving in 2WD. The front wheels then spin freely without turning the front axle shafts and differential. When you need 4WD, you lock the hubs so drive reaches the front wheels.

What are the benefits of free wheel hubs?

Unlocking the hubs in 2WD reduces wear on front driveline components such as CV joints, axle shafts and the front differential, and can reduce fuel use on the highway. Working hubs also mean your 4WD engages reliably when you select 4WD.

What's the difference between manual and automatic locking hubs?

Manual locking hubs are engaged by turning a dial on each front wheel before selecting 4WD. Automatic locking hubs engage on their own when 4WD is selected. Many owners upgrade to manual hubs because they give a positive, visible lock and don't rely on the automatic mechanism.

How do I know if my free wheel hubs need replacing?

Common signs include hubs that won't lock or unlock, slipping or clicking under load in 4WD, grinding noises from the front wheels, and a dial that's stiff or seized. Worn hubs can stop your 4WD engaging when you need it, so it's worth replacing them before your next off-road trip.

How do I choose the right free wheel hub for my vehicle?

Match your vehicle's make and model code first, then check the bolt count, PCD (the diameter of the bolt circle, in mm) and spline count against your existing hub. If you're unsure, contact us with your vehicle details before ordering.

Can I install free wheel hubs myself?

Free wheel hubs generally bolt onto the existing wheel hub, so confident home mechanics can often fit them with standard tools. If you're not comfortable working on your front axle, have a 4WD workshop fit them.

Should I lock my hubs before driving off-road?

Yes. Lock both front hubs before engaging 4WD, and unlock them when you return to sealed roads and 2WD. Always lock or unlock both sides together.

When should I receive my free wheel hubs?

An in-stock item usually ships within two business days. Depending on the item and where it's going, delivery takes 2–7 business days.
