Parts for your 1993 Suzuki Jimny-Centre bearing

1993 Suzuki Jimny centre-bearing — is it even a thing?

Short answer: for the standard 1993 Suzuki Jimny (known in Australia and New Zealand as the Sierra or SJ413 short‑wheelbase), a centre bearing isn’t used or relevant. The rear propeller shaft is a single piece, so there’s no centre support bearing fitted from factory.

This isn’t just hearsay. The Suzuki SJ413/Samurai factory service manual (Driveshaft/Propeller Shaft section, late 1980s–mid 1990s editions) shows a single‑piece rear shaft on the short‑wheelbase models with no carrier/centre support. The Suzuki Electronic Parts Catalogue (EPC) listings for SJ413 and the Japanese‑market JA11/JA12 Jimny of the same era also omit a centre bearing for the short‑wheelbase vehicles. Conversely, those EPC fiches do list a propeller‑shaft centre support for the long‑wheelbase “Sierra/Samurai Wagon/Long” variants, which have a two‑piece rear shaft.

Why the difference? It comes down to length and packaging. The short wheelbase Jimny/Sierra has a compact layout, so a single‑piece rear tailshaft is the simplest, strongest and most cost‑effective solution, with no need for an intermediate support. Adding a centre bearing would just introduce another wear item without any real benefit on the short shaft length.

Where a centre bearing does appear is on long‑wheelbase derivatives built in the same period (often called Sierra/Samurai “Long” or “Wagon” in local market materials). Those use a longer, two‑piece rear prop shaft to manage driveline angles and vibration, and that setup requires a centre support bearing mounted to the chassis crossmember. If your 1993 Suzuki is one of those long‑wheelbase variants, then a centre bearing is part of the driveline. If it’s the common short‑wheelbase Jimny/Sierra, it isn’t.

If you’re unsure what you’ve got, a quick look underneath will tell the story: one continuous rear shaft from the transfer case to the diff (no centre bearing), or two shafts with a rubber‑mounted support bracket about midway (centre bearing present).

FAQs

Does a 1993 Suzuki Jimny have a centre bearing?
Most 1993 Jimny/Sierra short‑wheelbase models do not have a centre bearing. They use a single‑piece rear prop shaft that doesn’t require a carrier support. Long‑wheelbase variants from the same era do have a centre bearing because they use a two‑piece rear shaft.

How can someone tell if their 1993 Jimny is the long‑wheelbase type with a centre bearing?
Crawl under the vehicle and look at the rear prop shaft. If there’s a bracket and rubber‑mounted bearing roughly halfway along supporting a joint between two shaft sections, that’s a centre bearing—so it’s a long‑wheelbase setup. If there’s just one continuous shaft, it’s the short‑wheelbase layout with no centre bearing.

If a centre bearing is fitted (long‑wheelbase), what maintenance is sensible?
Inspect the rubber mount for cracking, check for play or rumbling at the bearing, and keep an ear out for droning or vibration on overrun—classic signs of wear. It’s good practice to check it every 10,000–15,000 km along with the driveline uni joints, and replace the centre bearing assembly if there’s movement, noise, or perished rubber.
