Parts for your 2020 Subaru Impreza-Struts

2020 Subaru Impreza struts: fitment, purpose and service advice

Struts are absolutely relevant to the 2020 Subaru Impreza. Technical sources confirm the model uses MacPherson struts at the front and a double-wishbone setup at the rear. Subaru’s 2020 Impreza Owner’s Manual (Specifications – Suspension) lists a “front MacPherson-type” arrangement, and the Subaru Service Manual’s Front Suspension (FS) section details removal and installation of the front strut assembly. Aftermarket catalogues from KYB and Monroe for AU/NZ also list front struts and top mounts specifically for the 2020 Impreza, further confirming fitment.

On this model, the front strut is a structural assembly that combines a shock absorber, coil spring, and top mount. It locates the steering knuckle, supports vehicle weight, damps bumps, and keeps the Impreza tracking straight under braking and through corners. The top mount and bearing let the strut rotate smoothly with the steering, while the internal valving and spring control body motion, helping preserve tyre contact and even wear.

For owners and fleets, good struts mean confident turn-in, predictable braking, and less fatigue on rough Kiwi and Aussie roads. Worn units show up as clunks over potholes, nose-dive, floaty rebound, tramlining, or feathered/ cupped tyre wear. Service pros typically recommend inspection every 20,000 km or 12 months, looking for oil weep at the strut body, damaged dust boots or bump stops, perished top mounts, and uneven ride height.

• Expected life varies with conditions, but many Impreza front struts last 80,000–120,000 km before performance noticeably tails off.
• Replace in pairs on the same axle to keep damping and ride height balanced.
• Always book a wheel alignment after strut work to restore camber/caster/toe.
• It’s smart to renew related hardware at the same time: top mounts/bearings, boots, bump stops and spring isolators.
• Torque fasteners to Subaru specs at normal ride height, incorrect preload can creak or skew alignment.
• Because coil springs store significant energy, safe removal/installation needs proper compressors and workshop technique.

Quality OE-equivalent struts restore factory feel, cut braking distances on rough surfaces, and protect new tyres. Using the Subaru service manual procedures and specs ensures the Impreza’s front end stays tight, quiet and predictable for the long run.

Popular questions about 2020 Subaru Impreza struts

How long do the front struts typically last?
In normal Australian and New Zealand driving, many see 80,000–120,000 km before performance drops off. Rough roads, heavy loads and lots of city speed bumps can shorten that. Annual inspections pick up leaks or top-mount wear before it affects handling or tyres.

Should front struts be replaced in pairs?
Yes. Replacing both fronts together keeps damping and ride height even, which protects steering feel and tyre wear. Follow up with a four-wheel alignment to reset geometry.

What are the tell-tale signs the Impreza’s front struts are worn?
Common flags include clunks over bumps, longer braking distances on corrugations, nose-diving, floaty rebound, steering wander, and uneven tyre wear such as cupping or feathering. Visible oil weep on the strut body or cracked top mounts are also clear cues.
