Parts for your 2010 Lexus Is-Centre bearing

2010 Lexus IS centre-bearing — fitted, what it does, and how to look after it

Based on technical sources, the 2010 Lexus IS (XE20 series — IS 250/350, RWD and AWD, and IS F) is equipped with a two-piece propeller shaft that uses a centre support bearing. The Lexus/Toyota Repair Manual for this generation includes procedures titled “Propeller Shaft — Remove/Install Centre Support Bearing”, and the Toyota Electronic Parts Catalogue lists a “Bearing Assy, Center Support, Propeller Shaft” for these models. That makes the centre-bearing relevant and serviceable on the 2010 Lexus IS.

On this model, the centre-bearing sits mid-way along the two-piece driveshaft, cradled in a rubber carrier. Its job is to support the shaft, control vibration, and keep everything running true as torque heads to the rear wheels. When it’s healthy, the car feels smooth and quiet at motorway speeds, when it’s tired, owners often report a shudder on take-off or a droning vibration between about 40–80 km/h.

There’s no fixed replacement interval — it’s a condition-based item — but routine inspections during servicing are smart, especially past 100,000 km or if the car sees rough roads. The rubber isolator can crack with age and heat, and the bearing can dry out or loosen. Catching it early avoids you chasing NVH gremlins and protects the rest of the driveline.

Replacement is a workshop job. The bearing is pressed onto the prop shaft and sits in a carrier bracket. Proper marking of the shaft halves (to keep phasing and balance) is critical, as is torquing the flange fasteners to spec. Many IS models have non-serviceable (staked) universal joints, so while the centre-bearing can usually be replaced on its own, any excessive play in the U-joints may push the job towards a full shaft assembly.

• Watch for: vibration under light throttle, a thump on take-off, or a humming that changes with road speed.
• Inspect: carrier rubber for cracking, bearing play/roughness, mounting hardware, and shaft alignment marks.
• When replacing: use quality parts, keep the shaft phased, and consider new hardware. A road test for NVH after refit is a must.

Looked after properly, the centre-bearing helps the 2010 Lexus IS stay the quiet, refined drive it’s meant to be, whether it’s the daily commute or a long Kiwi/Aussie road trip.

FAQs

Does a 2010 Lexus IS have a centre-bearing?
Yes. The XE20-series IS uses a two-piece propeller shaft with a centre support bearing. Lexus/Toyota workshop literature includes centre-bearing service procedures, and the Toyota parts catalogue lists the carrier/bearing assembly for IS 250/350 and IS F, in both RWD and AWD variants.

What are the signs the centre-bearing is failing on a 2010 IS?
Common clues are a shudder on take-off, a droning or humming that follows road speed, and a vibration around 40–80 km/h. Visual checks often reveal cracked carrier rubber or noticeable play/roughness in the bearing when the shaft is unloaded.

Can the centre-bearing be replaced without changing the whole driveshaft?
Often yes — the centre-bearing and carrier can be pressed off/on. The prop shaft halves must be marked to preserve phasing, and flange bolts torqued correctly. If the U-joints (which may be staked from factory) show play or binding, a complete shaft assembly can be the more reliable fix.
