Parts for your 2023 Mitsubishi Triton-Wheel hubs

2023 Mitsubishi Triton wheel-hubs — what they do and how to look after them

Technical sources including the Mitsubishi Triton MR Service Manual (Front Axle/Hub sections), the Mitsubishi ASA electronic parts catalogue for MR Triton, and the 2023 Triton Owner’s Manual confirm the 2023 Mitsubishi Triton is fitted with wheel hubs front and rear. The hubs carry the wheel studs and brake hardware, house or interface with the wheel bearings, and on 4x4 models transmit drive. While older utes sometimes used manual free‑wheeling hubs, the 2023 Triton uses an automatically controlled front axle disconnect (Easy Select or Super Select), so there are no manual lock hubs at the wheels—yet the wheel-hub assemblies themselves are very much present and serviceable.

On a 2023 Triton, the front hub and bearing support the wheel, manage cornering loads, and keep the ABS/speed sensing accurate via an encoder ring. At the rear live axle, the wheel-hub works with the pressed-on axle bearing and seals to keep everything running true under load. In everyday terms, the hubs are what let the wheels spin smoothly, keep tyres wearing evenly, and ensure the ute tracks straight whether it’s towing, on corrugations, or heading into the bush.

Good servicing habits make a big difference. During routine services, a tech should check for play, roughness and seal weep, spin the wheels for humming or growling, inspect ABS wiring and sensor gaps, and confirm the wheel studs and nuts are in top nick. After water crossings, beach runs or heavy towing, it’s worth an extra listen for any new noises and a recheck at the next service, as water and heat can shorten bearing life.

Replacement is advised when there’s noticeable hum that rises with speed, clunks when rocking the wheel at 12 and 6 o’clock, ABS warning lights, heat around the hub after a drive, or cupped tyre wear. On Triton MR, the front bearing is a press-fit into the steering knuckle with a separate hub flange, special tools are required and new seals, snap rings and often the axle nut should be renewed. At the rear, the bearing is pressed to the axle shaft and paired with a new seal and retainer. Avoid hammering the hub, keep the magnetic encoder clean, and always tighten fasteners to the Mitsubishi specs in the service manual. A post-repair alignment check is a smart move if any front-end components were disturbed.

• Common signs of hub/bearing wear: speed-dependent hum, vibration through the seat or steering, ABS faults, uneven tyre wear.
• Typical lifespan varies with load and use, many see well over 150,000 km with sensible servicing.

Popular questions about 2023 Mitsubishi Triton wheel-hubs

Do 2023 Tritons have manual locking hubs?
They don’t. The MR-series Triton uses Easy Select or Super Select 4WD with an automatic front axle disconnect, so there are no manual free‑wheeling hubs at the wheels. The wheel-hubs are fixed, while engagement is managed inside the front axle assembly and transfer case, as outlined in the Owner’s Manual and Mitsubishi technical training material.

How can someone tell if a Triton’s front hub/bearing is on the way out?
Listen for a humming or growl that changes with speed or when gently swerving left and right, feel for vibration through the seat, and check for play when the wheel is rocked at the rim. An ABS light or heat around the hub after a short drive are also red flags. Any of these call for inspection and likely bearing/hub service.

Can the bearings be replaced without changing the whole hub?
Up front, the Triton’s bearing is pressed into the steering knuckle with a separate hub flange, so the bearing itself can be replaced with the right press tools and new seals/clips. At the rear live axle, the bearing and seal are pressed to the axle shaft. In both cases, follow the Mitsubishi service manual procedures and torque specs.
