Parts for your 2013 Lexus Is-Centre bearing

2013 Lexus IS centre-bearing

Yes — the 2013 Lexus IS uses a centre-bearing (also called a centre support bearing) on its two-piece propeller shaft. This is shown in the Lexus Repair Manual’s Propeller Shaft section for the XE20 series (IS 250/350 and IS F), and in the Toyota/Lexus Electronic Parts Catalogue, which lists a “Bearing Assy, Centre Support, Propeller Shaft” for 2006–2013 IS variants, including rear-wheel drive and all-wheel drive models.

On the 2013 Lexus IS, the centre-bearing supports the two-piece driveshaft between the transmission and rear differential, keeping everything running smooth and quiet. By suspending the shaft on a rubber-mounted bearing midway along the car, it controls vibration, manages shaft angles over bumps, and reduces noise in the cabin — exactly the refined behaviour Lexus owners expect.

Over time, the rubber isolator can crack or sag and the bearing itself can wear. Typical signs that the centre-bearing needs attention include:

• A thump or shudder on take-off or during gear changes
• Droning or whirring that rises with road speed
• Noticeable vibration under load or on overrun
• Visible tearing or excessive play in the support rubber

As part of regular servicing, it’s smart to inspect the bearing and bracket every 60,000–100,000 km, or sooner if the car tows, drives on rough roads, or has been lowered. Look for cracked rubber, rust-coloured dust from a dry bearing, and any misalignment. Also check adjacent parts: the transmission mount, differential mounts, universal joints, and any couplings, because wear there can mimic the same symptoms.

When replacement is due, the job involves removing the prop shaft, keeping its phasing and balance intact. Mark the flanges and shaft halves before separation, use the correct torque settings on reassembly, and follow Lexus specs for bracket alignment. Some genuine applications bundle the centre-bearing with the complete propeller shaft, while quality aftermarket options may allow a bearing-only replacement — just note that pressing the bearing on and off needs the right tools, and a balance check is recommended if the shaft is split.

Given the role this little hero plays in driveline smoothness, owners who chase down early noises and vibrations will usually save money and keep that trademark Lexus calm on every commute.

• Use OEM-quality parts for long life and low NVH
• Recheck fasteners and road test after any driveline work
• Address oil leaks that can degrade the support rubber

Popular questions

Does the 2013 Lexus IS have a centre-bearing?
Yes. The XE20-series IS (including IS 250, IS 350 and IS F) uses a two-piece propeller shaft with a centre support bearing from factory, as shown in the Lexus Repair Manual and Toyota/Lexus EPC listings.

What symptoms point to a failing centre-bearing on a 2013 IS?
Common clues are a take-off thump, driveline vibration that changes with speed, and a low-frequency drone. A visual check may reveal cracked or sagging rubber around the bearing bracket.

Can the centre-bearing be replaced separately?
Often yes with quality aftermarket parts, though Lexus may supply it as part of the complete prop shaft. If replacing the bearing alone, keep the shaft in phase, press the new bearing correctly, and consider a balance check.
