Parts for your 1990 Mitsubishi Pajero-Centre bearing

1990 Mitsubishi Pajero centre bearing

Based on factory references — Mitsubishi Pajero (L040) Workshop Manual, Group 22 Propeller Shaft, the Mitsubishi ASA electronic parts catalogue for 1990 Pajero, and Gregory’s/Haynes manuals covering 1983–1991 models — a centre bearing is used on 1990 Pajero long‑wheelbase (5‑door) models because they run a two‑piece rear propeller shaft with a hanger (centre) support. Short‑wheelbase (3‑door) models typically use a single‑piece rear shaft and therefore do not have a centre bearing.

For vehicles that have it fitted, the centre bearing is a simple hero part that keeps the two‑piece tailshaft aligned, supporting the shaft in the middle so it can spin smoothly under load. On a 1990 Pajero LWB, it helps control driveline angle changes as the suspension moves, cuts down vibration on take‑off, and takes stress off the universal joints. The rubber insulator in the hanger isolates noise and harshness, which is why a tired bearing often announces itself with a low drone, shudder under acceleration, or a dull clunk when shifting from drive to coast.

Servicing wise, it’s smart to inspect the centre bearing at regular intervals — especially on vehicles that tow, run bigger tyres, or see corrugations. Look for cracked or split rubber, sagging of the hanger, or any roughness when the shaft is rotated by hand. If the rubber is perished or the bearing feels gritty, replacement is the go.

When replacing, mark the prop shaft flanges before removal so the phasing goes back exactly as it came out. It’s a good time to check the universal joints for play and re‑grease serviceable ones. Many owners choose an OE‑quality bearing and mount because cheap rubber can collapse early in Aussie and Kiwi conditions. After refit, torque the flange bolts to workshop manual spec and road test, watching for any residual vibration. If there’s still a shake at certain speeds, a driveline balance may be needed.

Owners of short‑wheelbase 1990 Pajeros don’t have a centre bearing to worry about, Mitsubishi used a single‑piece shaft on those models to save weight and complexity given the shorter wheelbase and shaft length.

• Common symptoms of a failing centre bearing: acceleration shudder, mid‑shaft rumble, hanger rubber tears, and visible shaft misalignment.
• Best practice during service: inspect mount rubber, check U‑joints, confirm shaft phasing, and tighten to spec.

FAQs

Does a 1990 Mitsubishi Pajero have a centre bearing?
Long‑wheelbase (5‑door) models do — they run a two‑piece rear prop shaft supported by a centre (hanger) bearing. Short‑wheelbase (3‑door) models generally don’t, as they use a single‑piece rear shaft that doesn’t need mid‑span support.

What are the signs the centre bearing is worn on a 1990 Pajero?
Typical signs include a droning noise that rises with road speed, a shudder on take‑off, a clunk when going on and off the throttle, or a centre hanger rubber that’s cracked or sagging. If left, it can accelerate U‑joint wear.

Can it be driven with a failing centre bearing?
It might still move, but it’s not wise. A failing bearing can worsen quickly, creating vibration that can damage the tailshaft, U‑joints, or diff pinion seal. Best bet is to book it in and sort it before a trip or tow.
