Understanding Strut Mounts on the 2020 Subaru Impreza

The 2020 Subaru Impreza features a suspension setup that is quite typical for modern compact cars but does not utilise traditional strut mounts in the way you might expect on other vehicles. Unlike some models that employ MacPherson struts with distinct strut mounts at the top of the assembly, the 2020 Impreza uses a suspension system with separate shock absorbers and coil springs, resulting in a configuration where the term strut mount is not applicable.

To break it down, the Subaru Impreza's front suspension uses a MacPherson strut design that integrates the shock absorber and spring into one unit, but the mounting method varies. Instead of a rubber or bearing component identified specifically as a strut mount, the 2020 Impreza uses a top mount that functions more like a bearing plate and spring perch combination, designed to provide structural support and some cushioning while also enabling the suspension to pivot smoothly during steering. This means that while there is a mount at the top of the strut assembly, it is not a strut mount in the traditional sense that includes a bearing or isolator generally referred to in other vehicles.

Given this setup, the Impreza's suspension design does not require a replaceable strut mount component separate from the top mounting plate of the assembly. Instead, wear and tear issues more commonly arise in the shock absorber or spring itself or in related bushings and suspension arms. So, for this reason, discussions around strut mount replacement specifically are less common and less relevant for the 2020 Subaru Impreza.

However, if one were to look at servicing the top mounting areas on this vehicle or general strut servicing, it's helpful to understand what strut mounts do in vehicles that use them, and why maintaining these components is important for ride quality and suspension longevity.

Strut mounts are vital components in any MacPherson strut suspension system where the shock absorber and spring are combined into one assembly. They effectively connect the strut to the vehicle's chassis, acting as an interface between the suspension and the car body. Their purpose is to securely hold the strut in place while allowing it to pivot during steering. Most strut mounts also have a rubber or elastomeric layer to absorb road vibrations and noise, making for a smoother, quieter ride.

In some vehicles, strut mounts contain a bearing or thrust bearing that facilitates the rotation of the strut when the driver turns the steering wheel. A worn or failing strut mount can lead to a series of symptoms that affect drivability and comfort. This includes clunking noises over bumps, excessive vibration in the cabin, uneven tyre wear, and even steering difficulties. Because these mounts also absorb shock and vibration, their degradation over time means the suspension won't perform as intended, ultimately impacting safety.

When it comes to maintaining or replacing strut mounts, it is typically recommended to inspect them whenever the struts or shocks are serviced or replaced. This is because strut mounts generally wear roughly in the same timeframe as the struts, and replacing them simultaneously can save considerable labour costs and prevent future issues. Failure to replace worn strut mounts can lead to premature wear on new struts and poor handling characteristics.

For car owners servicing their 2020 Subaru Impreza, while the specific strut mount might not be a separate service item, regular inspection of the entire suspension system is key. This includes checking for any unusual noises coming from the front suspension, inspecting bushes and mounts for cracks or deterioration, and ensuring that the shock absorbers themselves are functioning optimally. A comprehensive suspension check as part of routine servicing helps catch early signs of wear and ensures the car maintains its sharp handling and comfortable ride.

Most mechanics or service centres advising on replacements for a 2020 Impreza will focus on the integrity of the shock absorbers, springs, and related mounting hardware. It's worth noting that Subaru's design aims to reduce complexity, which often means fewer replacement parts but does require the attention of those mounting points to detect any signs of fatigue or damage.

For drivers interested in maintaining their Subaru Impreza's suspension system for maximum performance and comfort, it is recommended to follow the manufacturer's service schedule and address any suspension noises or handling changes promptly. Having the suspension thoroughly inspected during services, especially after driving on rough roads or after an accident, can prevent more significant and costly repairs later. Ultimately, even though the 2020 Impreza does not use traditional strut mounts, the top suspension mounts and related components still require attention to keep your ride safe and comfortable.
