Parts for your 2017 Subaru Impreza-Driveshafts

2017 Subaru Impreza driveshafts: what they do and when to service them

Technical sources confirm that the 2017 Subaru Impreza uses driveshafts. In AU and NZ markets the model is equipped with Subaru’s Symmetrical All‑Wheel Drive, which includes front CV axle shafts, a propeller shaft linking the transmission to the rear differential, and rear CV axle shafts. This layout is documented in the Subaru 2017 Impreza Service Manual (Drive Shaft System and Propeller Shaft sections) and reflected in the Subaru parts catalogue for the 2017 Impreza (GK/GT platform). So yes—driveshafts are absolutely relevant on this vehicle.

On a 2017 Impreza, the driveshafts transfer torque smoothly from the transmission to the wheels via constant‑velocity (CV) joints, while the prop shaft sends power to the rear diff to keep AWD doing its thing. The aim is quiet, vibration‑free delivery of power through corners and over bumps. When they’re healthy, owners barely notice them, when they’re not, they’ll definitely hear or feel it.

There’s no fixed replacement interval for driveshafts on this model. Instead, they benefit from regular inspection as part of routine servicing—think every 10,000–15,000 km or at each scheduled service. A mechanic should check CV boots for splits, seepage, or thrown grease, feel for joint play, and road‑test for noise and vibration. The prop shaft on many Subaru models of this era has non‑serviceable, staked U‑joints and a centre support bearing that’s replaced as an assembly if worn, a point noted in Subaru’s service literature.

• Common signs of trouble: clicking on turns (outer CVs), clunks on take‑off, shudder or vibration under load or at speed, grease flung around the inner guard, or a humming/whirring from the centre bearing area.
• Good practice during replacement: use quality new or Subaru reman shafts, fit new axle nuts and seals where applicable, torque fasteners correctly, and mark prop shaft orientation before removal to help preserve balance.
• Tyres matter on AWD: keep tyre sizes, brands, and wear levels matched to protect the driveline and prevent undue stress on the centre coupling and shafts.

If a CV boot is torn but the joint hasn’t run dry, a timely boot and grease refresh can save the shaft. Once a joint starts clicking or a prop shaft develops play, replacement is the sensible call. After work is done, a quick alignment check and an extended road test will confirm the repair is spot‑on.

FAQs

Does the 2017 Subaru Impreza have a driveshaft?
Yes. With Symmetrical AWD, it has front and rear CV axle shafts plus a propeller shaft to the rear differential. This is outlined in Subaru’s 2017 Impreza service information and parts listings.

How long do the CV axles and prop shaft usually last?
It varies with driving and climate. Many see well over 100,000 km without drama. Regular checks for torn boots, thrown grease, or vibration help catch issues early and extend service life.

Is it safe to drive with a clicking CV joint or driveline vibration?
Short term, gentle driving might be possible, but it can worsen quickly and risk further damage. Best to schedule an inspection and repair promptly to keep the AWD system healthy.
