Parts for your 2004 Mitsubishi Lancer-Centre bearing

2004 Mitsubishi Lancer centre bearing — does it have one?

For the mainstream 2004 Mitsubishi Lancer (CS/CH series, front‑wheel drive), a centre bearing isn’t fitted and isn’t required. This is confirmed by Mitsubishi’s factory Workshop Manual for the CS/CH Lancer (2002–2007), which details a front‑wheel‑drive transaxle with left and right drive shafts and CV joints, but no propeller shaft or centre support bearing. The Mitsubishi ASA electronic parts catalogue likewise lists no centre support bearing for the CS/CH FWD models, while the Haynes Mitsubishi Lancer 2002–2010 manual describes the same FWD layout without a centre bearing.

Why no centre bearing? A centre (or centre support) bearing is used to support a long, two‑piece propeller shaft on rear‑wheel drive or all‑wheel drive vehicles. The standard 2004 Lancer is front‑wheel drive, so it doesn’t have a prop shaft running to the rear. Power goes from the transaxle directly to the front wheels via two short drive shafts with inner and outer CV joints, so there’s nothing long enough to need a centre support. Simple as that.

There is one well‑known exception in the broader Lancer family: the 2004 Lancer Evolution (CT9A, AWD) uses a two‑piece propeller shaft and does have a centre support bearing. Mitsubishi’s Workshop Manual sections covering the AWD driveline and the ASA parts catalogue list a prop shaft and support bearing specifically for Evolution models, not for standard CS/CH FWD variants.

Owners sometimes mistake other noises or vibrations for a “bad centre bearing” on a FWD Lancer. When chasing those symptoms on a 2004 Lancer, the usual suspects are:

• Front wheel bearings (droning that changes with road speed)
• Inner/outer CV joints (clicking on full lock or shudder under load)
• Engine and transmission mounts (clunks or harshness on take‑off)
• Tyre wear or out‑of‑round tyres (rhythmic humming or vibration)

Some FWD variants may also use an intermediate right‑hand driveshaft with a bracketed support bearing, which is different to a prop‑shaft centre bearing and is serviced as part of the driveshaft assembly. The factory Workshop Manual’s front axle/driveshaft section covers inspection and service for those components where fitted.

Does a 2004 Mitsubishi Lancer have a centre bearing?

No, not on the standard front‑wheel drive CS/CH models. They don’t use a propeller shaft, so there’s no need for a centre support bearing. Only the AWD Lancer Evolution of the same era uses a centre bearing.

What could sound like a bad centre bearing on a FWD 2004 Lancer?

Common culprits are front wheel bearings, worn CV joints, tired engine/gearbox mounts, or unevenly worn tyres. These can cause droning, clicking, or vibration that people sometimes attribute to a non‑existent centre bearing.

Which 2004 Lancer models actually use a centre bearing?

The Lancer Evolution (CT9A) does, because it’s AWD with a two‑piece propeller shaft. The Mitsubishi Workshop Manual and ASA parts catalogue list the prop shaft and centre support bearing for Evolution models only.
