Parts for your 2009 Lexus Is-Universal joints

2009 Lexus IS universal joints: what they do and how to look after them

Per Lexus/Toyota factory technical sources (Toyota TIS Repair Manual: Propeller Shaft, IS 2006–2013 GSE20/GSE21/GSE25, and the Toyota/Lexus Electronic Parts Catalogue for the same series), the 2009 Lexus IS uses universal joints in its driveline. Rear‑wheel‑drive models have a two‑piece propeller shaft with a universal joint at each end and a centre support bearing, AWD variants also add a front propeller shaft with universal joints. So, universal joints are absolutely relevant to this vehicle.

On the 2009 IS, the universal joints (U‑joints) allow the prop shafts to transmit power smoothly while the gearbox, diff, and suspension all move relative to each other. They handle angle changes, keep vibration in check, and help deliver that tidy Lexus refinement at motorway speeds and around town.

From a service point of view, the factory U‑joints are sealed and not normally greaseable, so there’s no routine lubrication called out in the factory schedule. What matters is periodic inspection. At each major service, a good workshop will check for play, dry or torn seals, rust staining around the bearing cups, and any notchiness as the joint is articulated by hand. They’ll also road‑test for driveline vibration and “clunks” on take‑off or when shifting from reverse to drive.

If a U‑joint is worn, owners should know Toyota/Lexus typically supply the propeller shaft as a complete assembly. Many genuine shafts have staked‑in joints, so replacing just the joint isn’t an OEM procedure. A driveline specialist can often machine out the staked joints, fit quality circlip‑type joints, and re‑balance the shaft to spec — a smart option if the rest of the shaft is in good nick. Either way, balancing and correct phasing are crucial to avoid vibration.

• Common warning signs: clunk on take‑off, chirping or squeak that changes with speed, shudder under load, visible slop at the joint.
• Inspection cadence: every 20,000–30,000 km or at annual/major services, sooner if the car tows, sees rough roads, or has been lowered.
• Don’t ignore symptoms: a failed U‑joint can damage the centre bearing, yokes, or diff pinion, and in extreme cases lead to shaft failure.
• AWD note: the front prop shaft has its own U‑joints—apply the same checks there.

Look after the U‑joints and the IS will stay buttery‑smooth and happy on Kiwi and Aussie roads alike.

Popular questions

Does a 2009 Lexus IS actually have U‑joints?
Yes. Factory repair documentation for the 2006–2013 IS platform shows a two‑piece rear propeller shaft with universal joints, and AWD models add a front prop shaft with U‑joints as well. They’re a normal part of the driveline on this car.

Can the U‑joints be greased on a 2009 IS?
The original Lexus joints are sealed, non‑greaseable items. Routine maintenance is inspection rather than lubrication. Some aftermarket or specialist‑repaired shafts may use greaseable joints, if fitted, they should be greased at regular service intervals.

Do U‑joints on the IS get replaced separately or as an assembly?
From the dealer, the propeller shaft is usually supplied as a complete assembly because the factory joints are staked in. A driveline specialist can often replace just the joints and re‑balance the shaft, which can be cost‑effective if the shaft itself is sound.
