2017 Subaru Impreza Shock-Absorbers: What They Do and When to Replace

Shock-absorbers are absolutely fitted to the 2017 Subaru Impreza. Subaru’s technical literature for the 2017MY Impreza (Service Manual, Chassis/Suspension) specifies a MacPherson strut front suspension and an independent double-wishbone rear, with gas-pressurised dampers. The Owner’s Manual and workshop data likewise refer to inspection of struts/shocks as part of routine maintenance. So yes—this model relies on shock-absorbers to keep the tyres planted and the ride tidy.

On the road, the shocks do far more than smooth out bumps. They control spring movement, help maintain tyre contact, and keep body motion in check during braking, cornering, and over corrugations. Up front, the Impreza’s damper is integrated in the strut assembly, at the rear, the shocks work with the double-wishbone setup to deliver grip and comfort. When they’re healthy, the car steers cleanly, stops predictably, and feels composed—just what’s wanted for Aussie and Kiwi roads.

Shock-absorbers don’t have a fixed change interval, but they do wear. As a rule of thumb, have them inspected at every service, or at least every 20,000 km. Many owners see strong service life into the 80,000–150,000 km range, though rough surfaces, heavy loads, and potholes can bring that forward. A quick bounce test isn’t enough, proper checks look for leaks, uneven rebound, worn mounts, and cupped tyre wear.

• Common signs they’re due: longer stopping distances, floaty or bouncy ride, nose-diving under brakes, extra body roll, clunks over bumps, oily struts/shocks, and uneven tyre wear.
• Good practice on replacement: fit in axle pairs (both fronts or both rears), renew top mounts/insulators as needed, and get a wheel alignment after front strut work.

When it’s time, quality matters. Genuine or reputable aftermarket dampers matched to the Impreza’s Subaru Global Platform geometry will restore balance and braking feel. Re-torque all fasteners at ride height per workshop specs, and don’t forget to check sway bar links and control arm bushes while there—fresh shocks can highlight play elsewhere.

Keeping the Impreza’s shock-absorbers in shape means better grip in the wet, less tyre scrub, and a calmer cabin on long Kiwi or Aussie drives. It’s one of those jobs that quietly pays for itself in safety and comfort.

Popular questions about 2017 Subaru Impreza shock-absorbers

How long do the shocks typically last on a 2017 Impreza?
Service life varies with conditions, but many see 80,000–150,000 km before performance tails off. Lots of city kerbs, corrugations, or towing can shorten that. Regular inspections catch leaks and fade before they turn into tyre wear or braking issues.

Do I need an alignment after replacing shocks or struts?
Yes—especially after front strut work. Any time a strut is removed, camber and toe can shift. A post-fit alignment restores correct geometry, protects tyres, and keeps the steering wheel straight.

Can I replace just one shock?
Best practice is to replace shocks in pairs on the same axle. Mixing old and new can upset balance and braking. If one has failed prematurely, the opposite side has likely aged similarly.
