Parts for your 2015 Subaru Impreza-Strut mounts

2015 Subaru Impreza strut mounts

Based on technical documentation, strut mounts are fitted to the 2015 Subaru Impreza at the front. The Subaru 2015MY Impreza Factory Service Manual (Chassis, Front Suspension, MacPherson Strut) specifies a MacPherson front layout, which by design uses a top mount and bearing. The Subaru parts catalogue (Group 20, PNC 20320 “Support – Front Strut Mount”) lists left and right front strut mounts for this model. The rear uses an independent double-wishbone arrangement, so rear “strut” mounts aren’t applicable.

For the front end, the strut mount is the bit that ties the strut to the body and lets the strut rotate smoothly as the steering turns. It isolates noise and vibration, keeps alignment stable, and helps the car track straight on long Kiwi and Aussie highways. Inside the mount is a bearing that allows the spring and strut to twist without binding.

Owners of a 2015 Impreza should think of the strut mount as a wear item, much like the strut itself. There’s no fixed replacement interval, but inspection during scheduled servicing makes sense—especially every 40–60,000 km or whenever front-end work is being done. If the struts are being replaced, doing the mounts at the same time saves labour and helps the fresh dampers do their best work.

Common signs the front strut mounts are tired include:

• Clunks or creaks over speed humps or sharp driveways
• Notchy or heavy steering at low speeds (the top bearing binding)
• Front-end vibration, vague steering feel, or alignment that won’t stay put
• Cupped or uneven tyre wear at the front

Quality matters here. Genuine or reputable aftermarket mounts with integrated bearings tend to last longer and stay quiet. Replacement is done in pairs left/right, the coil spring is safely compressed off the car, the new mount and bearing are fitted, and the assembly is torqued correctly before refit. A wheel alignment afterwards is a must—expect crisper turn‑in and less tramlining when everything’s tight again. For anyone chasing WOF/reg inspection peace of mind, fresh mounts can tidy up borderline ride or noise issues that testers pick up on.

Driving on badly worn mounts can accelerate strut wear and chew through tyres, so it pays to sort them early rather than wait for a bigger bill later.

Popular questions about 2015 Subaru Impreza strut mounts

Do all 2015 Imprezas have front and rear strut mounts?
No. The front suspension is MacPherson strut and uses strut mounts with bearings. The rear is independent double wishbone, which uses separate shocks and springs, so there aren’t “rear strut mounts” in the same sense—just upper shock mounts that don’t rotate for steering.

What are the tell‑tale signs my front strut mounts are worn?
Listen and feel for low‑speed creaks or clunks, steering that feels notchy when parking, or a front end that wanders and won’t hold an alignment. Uneven front tyre wear and a thud over sharp bumps are also common clues.

When should the strut mounts be replaced?
There’s no set kilometre limit. They’re typically replaced when fitting new front struts, or as soon as noise, play, or bearing roughness shows up. Having them checked every major service or around 40–60,000 km helps catch issues early, and a post‑job wheel alignment is essential.
