Parts for your 2018 Mitsubishi Outlander-Centre bearing

2018 Mitsubishi Outlander centre-bearing — what’s fitted and what to service

Based on Mitsubishi’s technical literature, the 2018 Outlander uses a centre-bearing only on the petrol/diesel AWD (non‑PHEV) variants. The Mitsubishi Outlander Workshop Manual (ZK/ZL) in the Propeller Shaft section shows a two‑piece tailshaft with a centre support bearing on 4WD/AWD models. The Outlander PHEV technical guide outlines a through‑the‑road AWD layout with an electric rear axle and no mechanical propeller shaft, so there’s no centre-bearing on PHEV. The 2WD models likewise have no rear prop shaft, so the part isn’t relevant to them. Mitsubishi’s ASA/EPC parts catalogue also lists the centre support only against AWD VINs.

For those AWD 2018 Outlanders that do have it, the centre-bearing’s job is to support the middle of the two‑piece prop shaft, keeping it running straight and smooth while the body and driveline move around. It takes load off the universal joints, controls vibration, and uses a rubber insulator to soak up noise and harshness. When it’s healthy, the driveline feels settled, when it’s tired, you’ll often notice a shudder on take‑off, a rumble that follows road speed (not engine revs), or a thump during gear changes or on/off throttle.

There’s no greasing to do here — the bearing is sealed — so servicing is about inspection. During routine servicing (every 10,000–20,000 km or annually, as per your workshop schedule), a tech should:

• Check the rubber support for cracks, tearing or sagging, and feel for play at the bearing.
• Inspect the tailshaft for dents, missing balance weights and loose/damaged fasteners at the flanges.
• Look over nearby heat shields and exhaust clearances that can cook or rub the support.
• Note any driveline vibrations between 40–90 km/h, or a drone on overrun, and investigate promptly.

Replacement depends on parts availability. Mitsubishi commonly supplies the propeller shaft as a complete assembly, many workshops prefer this to protect balance and phasing. If fitting an aftermarket centre-bearing only, the shaft must be removed, flanges match‑marked, and the two halves kept in phase. Press work is required to swap the bearing, and correct reassembly, torque and threadlocker are essential. On a hoist, a competent shop will typically allow around an hour or two for R&,R and road test. After replacement, it’s smart to recheck bolt torque after a few hundred kilometres and confirm the AWD system operates without vibration or noise.

Why some 2018 Outlanders don’t have a centre-bearing: the 2WD models don’t use a rear prop shaft, and the PHEV’s rear axle is driven electrically with no mechanical link from the front, so there’s nothing that needs a centre support.

Does every 2018 Outlander have a centre-bearing?

No. Only the petrol/diesel AWD (non‑PHEV) models with a two‑piece prop shaft use a centre support bearing. The 2WD and PHEV versions don’t have a rear prop shaft, so there’s no centre-bearing fitted.

What are the common signs a centre-bearing is failing on an AWD 2018 Outlander?

Typical clues are a shudder on take‑off, a rumble or humming that follows road speed, and a thump on gear changes or when lifting off the throttle. Underneath, the rubber support may be cracked or sagging, and you might feel excess play at the bearing.

Can the centre-bearing be replaced on its own, or is a full tailshaft needed?

Workshops often replace the full prop shaft assembly to maintain balance and phasing. Some aftermarket bearings are available separately, but fitting them needs press work and careful reassembly. Your technician will advise based on parts supply, condition of the shaft and cost.
