2018 Toyota Corolla strut mounts — what they do and when to replace them
Based on Toyota’s own technical references — the Corolla New Car Features (E170/E180), the 2018 Corolla Repair Manual, and the Toyota Electronic Parts Catalogue — the 2018 Toyota Corolla runs MacPherson struts at the front and a torsion-beam rear with separate shock absorbers. That means front strut mounts are definitely used (Toyota calls them the Front Suspension Support Sub‑Assembly with an integrated bearing), while the rear does not use strut mounts.
On the front end, the strut mount sits at the top of the strut assembly, tying the suspension to the body and providing a smooth pivot for steering via a built‑in bearing. It carries vehicle weight, isolates road noise and vibration, and lets the strut rotate as the wheels are turned. When these mounts wear, the bearing can bind or the rubber can compress or crack, which knocks the alignment and ride quality about.
For everyday servicing of a 2018 Corolla, strut mounts aren’t a regular “consumable” like filters, but they’re smart to inspect any time the front struts are being assessed. Many techs in Australia and New Zealand will replace mounts and bearings whenever new front struts go in, because the labour overlaps and fresh mounts help protect the new dampers.
Typical signs the front strut mounts need attention include:
- Clunks or creaks over speed humps, driveways, or rough chip roads
- Steering that feels notchy or slow to self‑centre after a turn
- Uneven front tyre wear or alignment that won’t stay put
- Visible cracks, crushed rubber, or rust staining around the top mount
Replacement advice for a 2018 Corolla front end:
- Use a quality spring compressor and follow Toyota torque specs, the top nut and mount fasteners are critical.
- Renew the mount and the bearing as a pair, mixing old and new can cause noise or steering bind.
- Book a wheel alignment straight after the job, camber and toe will shift when struts are disturbed.
- Choose parts that suit local conditions — OE or reputable aftermarket mounts handle Aussie and Kiwi roads well.
While the rear doesn’t have strut mounts, the shock absorber upper bushings should still be checked for perishing during routine services. Keeping the front mounts healthy lets the Corolla steer sweetly, ride quietly, and keep tyres wearing evenly over the long haul.
Popular questions about 2018 Toyota Corolla strut mounts
Do 2018 Toyota Corollas have strut mounts?
Yes — on the front suspension only. The 2018 Corolla uses MacPherson struts up front, which require a strut mount with an integrated bearing. The rear is a torsion‑beam with separate shocks, so there’s no rear strut mount, just shock mounts and bushings.
How long do front strut mounts last on a 2018 Corolla?
In typical Australian and New Zealand conditions, many last 80,000–150,000 km, sometimes longer on smoother highways. Frequent corrugations, speed humps, heavy loads, or larger tyres can shorten their life. Inspect them whenever front struts are serviced or if steering and ride feel change.
Should strut mounts be replaced when fitting new front struts?
It’s strongly recommended. The labour overlaps, the bearing is a known wear item, and fresh mounts help prevent knocks and steering bind. Pairing new struts with new mounts and a post‑job alignment gives the best result and protects tyre wear.
