Parts for your 2013 Lexus Is-Wheel hubs

2013 Lexus IS wheel hubs: what they do and when to replace them

Wheel hubs are absolutely used on the 2013 Lexus IS. Technical references such as the Lexus/Toyota Repair Manual (TIS) for the 2013 IS (IS250/IS350/IS F) and the Toyota Electronic Parts Catalogue (EPC) list both a front “Hub (Sub‑Assembly), Front Axle” and a rear “Rear Axle Hub & Bearing Assembly.” On this model the front uses a hub pressed into a double‑row bearing within the steering knuckle, while the rear typically uses a bolt‑on, sealed hub/bearing unit with ABS tone ring. So, yes—wheel hubs are relevant and fitted to this vehicle.

On a 2013 Lexus IS, the hub is the solid mounting point for the wheel and brake rotor, keeping everything running true while the bearing lets it spin smoothly. It also carries the wheel studs and interfaces with the ABS/traction control system via a tone ring or encoder, so a crook hub or bearing can set off warning lights as well as cause noise or vibration.

They’re sealed and designed to be maintenance‑free, but a quick check at service time is smart. A technician will spin each wheel, feel for roughness, listen for a humming or growl that changes with speed, and check for play with the wheel off the ground. Any looseness, noisy running, or heat discolouration around the hub calls for replacement. Expect many hubs to last well past 150,000 km, but harsh roads, impacts, or water ingress can shorten that.

• Common symptoms: droning/humming that rises with speed, steering wheel vibration, ABS or traction light on, uneven tyre wear, or a hot hub after a drive.
• Front: the hub is pressed into the bearing in the knuckle. Replacement usually needs a press and proper support to avoid damaging the new bearing. No front axle nut on this RWD layout.
• Rear: typically a bolt‑on hub/bearing assembly. Renew any single‑use fasteners, torque to spec, and protect the wheel speed sensor.

After hub work, it’s good practice to check brake rotor runout, re‑torque wheel nuts after a short drive, and book an alignment if the knuckle’s been disturbed. Quality OEM‑spec parts and careful torqueing go a long way to quiet, long‑lived hubs on the IS.

FAQs

Does the 2013 Lexus IS have wheel hubs or hub assemblies?
Yes. The front uses a hub pressed into a bearing in the steering knuckle, and the rear generally uses a bolt‑on sealed hub/bearing unit. This layout is confirmed by Lexus/Toyota service information and the Toyota EPC.

How long do wheel hubs last on a 2013 IS?
Many last 150,000–250,000 km or more. Rough roads, kerb hits, or water intrusion can shorten life. Listen for humming that rises with speed, feel for play when the wheel is lifted, and watch for ABS lights—these are early clues it’s time to replace.

Can a home mechanic replace them?
The rear bolt‑on units are doable with the right tools and care around the ABS sensor. The front typically needs a press to seat the bearing and hub correctly, so many DIYers leave the front to a workshop to avoid damaging new parts.
