Parts for your 2013 Toyota Prius-Strut mounts

2013 Toyota Prius strut mounts — what they are, and when to replace them

Strut mounts absolutely are relevant to the 2013 Toyota Prius — at the front end. Technical sources including Toyota’s Repair Manual for the ZVW30 series (Front Suspension section, MacPherson strut layout) and Toyota’s parts catalogue identify a front upper strut mount with an integrated bearing. Reputable aftermarket catalogues (e.g., KYB and Monroe) also list dedicated front strut-mount kits for 2010–2015 Prius models. The rear of this Prius uses a torsion-beam with separate shock absorbers, so there are no rear strut mounts — just upper shock mounts/bushes.

On the front of a 2013 Prius, the strut mount’s job is twofold: it ties the strut into the body and supports vehicle loads, while the built-in bearing lets the strut rotate smoothly as the wheels steer. That bearing is what keeps steering light and on-centre, and the rubber insulator helps keep road harshness and cabin noise down. When it’s healthy, alignment stays true, tyre wear is even, and the steering feels predictable.

As part of routine servicing, a good workshop will check the front strut mounts for perished rubber, play in the bearing, rust around the top hat, and any movement at the top of the strut while someone rocks the wheel. In Aussie and Kiwi conditions — heat, wet weather, gravel and corrugations — the mounts and bearings can age faster. Many owners find they last somewhere between 120,000 and 200,000 km, but they can go earlier if the roads are rough or the car’s heavily loaded.

Common clues it’s time to replace them include:

• Clunks or knocks over speed bumps or potholes
• Creaks while turning at low speed, or “memory steer” (wheel doesn’t self-centre)
• Wandering or vague steering and uneven tyre wear
• Visible cracking of the rubber insulator

Best practice is to replace strut mounts in pairs and, if the struts are older, do them at the same time — it saves labour and resets the front end properly. Use new hardware and ensure the mount orientation marks are aligned correctly. After any strut or mount work, book a wheel alignment. A tidy, noise-free front end and straight steering wheel are the giveaways the job’s been done right.

FAQs

Do both front strut mounts need replacing together?
Yes, it’s smart to do both fronts at once. Mounts age at a similar rate, and replacing them as a pair avoids uneven steering feel or noise left-to-right. If the struts are old or leaking, have the shop fit new struts and mounts together and follow up with an alignment.

How long do Prius strut mounts usually last in Australia and New Zealand?
Many last 120,000–200,000 km, but hot summers, coastal corrosion, and rough or corrugated roads can shorten that. Listen for knocks and steering creaks, and have the mounts inspected during major services from around 100,000 km onward.

Could a front-end clunk be something other than the strut mounts?
Absolutely. Sway bar links, control arm bushes, ball joints, or the strut itself can also make noise. A proper inspection — checking mount play, link wear, and bush condition with the suspension loaded — will pinpoint the culprit before parts are ordered.
