Parts for your 1993 Mitsubishi Pajero-Centre bearing

1993 Mitsubishi Pajero centre-bearing — what applies and what to service

For a 1993 Mitsubishi Pajero, the centre-bearing (also called a carrier or centre support bearing) is fitted to long-wheelbase (LWB) models that use a two-piece rear propeller shaft. Short-wheelbase (SWB) models typically use a single-piece prop shaft and do not have a centre-bearing. This configuration is documented in Mitsubishi’s Workshop Manual for the V2/V4/V6 series (1991–1999) under Group 22 – Propeller Shaft, which shows a centre support bearing and hanger bracket for LWB vehicles, while SWB layouts are single-piece shafts without the support. Mitsubishi’s ASA electronic parts catalogue also lists a “Support, Propeller Shaft” (centre-bearing) for V24/V44 LWB variants (e.g., MB663627, superseded by MR131446) and none for SWB V23/V43. This is echoed by common aftermarket catalogues that supply centre-bearing kits for LWB Gen 2 Pajero/Montero (1991–1996) only.

On LWB 1993 Pajero models that do run a centre-bearing, the part’s job is simple but crucial: it supports the two-piece tailshaft mid-span, keeping the driveline aligned and reducing vibration as torque loads change and the suspension moves. That support helps the Pajero stay smooth on the highway and stable off-road, and it saves the universal joints and gearbox/transfer case mounts from copping unnecessary abuse.

As part of regular servicing, it’s worth giving the centre-bearing a look every 10,000–15,000 kilometres, or sooner if the vehicle tows, tackles corrugations, or spends life loaded up. Check the rubber isolator for cracking, separation, or sag, and feel for roughness or play in the bearing itself. Common red flags are shudder on take-off, a droning/whirring that changes with speed, or a clunk when loading and unloading the driveline.

When replacement time rolls around, the smart play is to mark the phasing of the tailshaft sections before removal, then press the old bearing off and fit the new one to the correct depth with the dust shields in place. Fresh hanger bushings and a check of the universal joints are sensible while it’s apart. Refit with proper torque on the flange bolts, ensure the hanger bracket isn’t twisted, and keep the tailshaft phasing as it was to prevent new vibrations. If the yokes are flogged out or the shaft’s out of balance, a rebuilt or exchange shaft can save headaches. After installation, a quick road test across different speeds and light/medium load will confirm it’s silky again.

Why some 1993 Pajeros don’t use a centre-bearing? SWB models run a shorter, single-piece prop shaft that doesn’t need mid-span support. The shorter length is stiff enough to control whip and angles without a carrier, which keeps the setup lighter and simpler for those variants.

• Mitsubishi ASA Parts Catalogue: V24/V44 LWB “Support, Propeller Shaft” MB663627 → MR131446, no centre support listed for SWB V23/V43.
• Aftermarket catalogues (e.g., bearing suppliers) list centre-bearing kits for Gen 2 LWB Pajero/Montero, confirming usage on those models.

FAQs

Does a 1993 Pajero SWB have a centre-bearing?
Generally, no. The SWB uses a single-piece rear prop shaft that doesn’t require a centre support. The centre-bearing is a feature of the LWB two-piece tailshaft setup.

What are the signs a 1993 Pajero LWB centre-bearing needs replacing?
Shudder on take-off, droning or humming that changes with speed, and a clunk when loading/unloading the driveline. Visual checks may show a cracked or sagged rubber isolator or noticeable play/roughness in the bearing.

Can the centre-bearing be replaced on its own?
Yes, the support bearing and rubber can be pressed off and replaced. Keep the tailshaft phasing marked, use quality components, and inspect U-joints. If the shaft or yokes are worn or out of balance, a rebuilt assembly might be the better fix.
