Parts for your 2019 Subaru Impreza-Strut mounts

2019 Subaru Impreza strut mounts — what they do and when to replace them

Strut mounts are absolutely relevant to the 2019 Subaru Impreza. Technical sources including the Subaru Impreza (GK/GT) service manual and Subaru parts catalog specify a MacPherson strut front suspension with an upper strut mount and bearing, while the rear uses a separate shock on a multi‑link/double‑wishbone layout. That means dedicated strut mounts are fitted on the front only, not the rear.

On the 2019 Impreza, the front strut mounts sit at the top of each front strut assembly, bolting the strut to the body’s strut tower. They isolate noise and vibration, keep the spring centred, and, crucially, contain the bearing plate that lets the strut turn smoothly with the steering. When they’re healthy, steering feels light and precise, road noise stays civil, and wheel alignment holds steady over bumps and corrugations common on Aussie and Kiwi roads.

There’s no fixed replacement interval, but they’re a wear item. A good rule of thumb is to have them inspected around 60,000–100,000 km or any time the front struts are out. Typical signs they’re tired include:

• Clunks or knocks over potholes or speed humps
• Heavy, notchy, or “memory steer” feel at low speeds
• Uneven tyre wear or vague turn‑in
• Visible rubber cracking, perished isolator, or rust around the studs

Best practice is to replace front strut mounts in pairs. Many techs will also renew the dust boots and bump stops at the same time, and it’s smart to inspect the springs and struts while it’s apart. Quality OEM‑equivalent parts from brands such as KYB (common OE on Subarus) keep the steering feel and NVH right where it should be.

Because the mount position and strut angle affect camber and caster, a four‑wheel alignment is recommended straight after the job. The work requires safe spring compression and correct “clocking” of the spring to the perch, so it’s worth organising a workshop that knows Subaru’s GK/GT platform torque specs and procedures.

Note: the rear of the 2019 Impreza isn’t a strut — it uses a separate shock and spring on a double‑wishbone arrangement — so there’s no rear “strut mount” in the MacPherson sense. The rear has shock mounts, which can also age, but they’re a different part and task.

Popular questions

Does the 2019 Impreza have strut mounts front and rear?
It has strut mounts on the front only. The rear suspension is a multi‑link/double‑wishbone with a separate shock and spring, so it uses rear shock mounts rather than strut mounts.

What symptoms point to worn front strut mounts on an Impreza?
Common giveaways are clunks over bumps, a creak or notch when turning at parking speeds, steering that won’t self‑centre properly, or uneven front tyre wear. Visual checks may show cracked rubber or rust around the top mount studs.

Is a wheel alignment needed after replacing strut mounts?
Yes. Disturbing the front strut assembly can shift camber and caster. A post‑repair alignment helps the car track straight, protects tyre life, and restores crisp steering feel.
