Parts for your 2013 Toyota Prius-Thrust bearing

2013 Toyota Prius thrust bearing — what it is and when it matters

For anyone chasing a “thrust bearing” on a 2013 Toyota Prius (ZVW30), here’s the go: there is no clutch release/throwout thrust bearing because the Prius uses Toyota’s Hybrid System transaxle (eCVT) with a planetary gearset and motor-generators, not a manual clutch or a conventional auto with a pressure plate (Toyota Prius ZVW30 New Car Features – Hybrid System). That makes a standalone clutch-type thrust bearing not relevant as a service part. That said, thrust-type bearings do exist on this model in two places: inside the engine as part of the crankshaft main/thrust bearing set (Toyota Repair Manual – 2ZR‑FXE Engine, crankshaft end play), and at the top of each front strut as the strut mount bearing, which carries axial (thrust) load while allowing the strut to rotate (Toyota Repair Manual – Front Suspension, front shock absorber/strut support).

For most owners and workshops, the “thrust bearing” worth talking about is the front strut mount bearing. Its job is to take the vehicle’s weight (a vertical, thrust load) and let the MacPherson strut turn smoothly with the steering. When it wears, steering can feel notchy or heavy, the front end may creak or groan at parking speeds, and the spring can “twang” as it sticks then releases during turns.

There’s no set replacement interval in the Toyota schedule, but practical servicing says: inspect the strut mounts and bearings any time front shocks/struts are replaced (often around 100,000–150,000 km, depending on conditions), or sooner if symptoms appear. It’s smart to replace mounts/bearings in pairs and follow up with a wheel alignment. Under the bonnet, check for perished rubber in the mount and any gritty, rough feel when the strut is rotated with the spring unloaded. If the bearing’s binding, noisy or has play, swap it out.

Replacement needs a proper spring compressor and care with torque specs, it’s one of those jobs best left to a competent tech. While you’re in there, inspect bump stops, dust boots and upper spring seats. Use quality OEM or reputable aftermarket parts to keep steering feel consistent and tyre wear even.

As for the engine’s crankshaft thrust bearing, it’s an internal component checked during overhaul via end float, it’s not a routine service item unless diagnosing specific engine issues (Toyota Service Information – Engine Mechanical, thrust clearance).

Question: Does the 2013 Prius have a clutch thrust/throwout bearing?

Answer: No. Its eCVT hybrid transaxle doesn’t use a manual-type clutch, so there’s no throwout thrust bearing. This is outlined in Toyota’s New Car Features for the ZVW30 hybrid system.

Question: Where is the thrust bearing people talk about on a Prius?

Answer: In normal servicing, they’re referring to the front strut mount bearing at the top of the MacPherson strut. The engine also has internal crankshaft thrust bearings, but those aren’t routine service parts.

Question: When should the Prius strut mount (thrust) bearings be replaced?

Answer: Replace them if steering feels notchy or noisy at low speeds, if there’s play in the mount, or whenever fitting new front struts. Do both sides and get an alignment afterwards.
