Parts for your 2019 Subaru Impreza-Driveshafts

2019 Subaru Impreza driveshafts

Based on technical sources including the Subaru Service Manual (2019MY Impreza), the Owner’s Manual, and Subaru Australia specifications for Symmetrical All-Wheel Drive, the 2019 Subaru Impreza is fitted with driveshafts. It uses front and rear CV driveshafts (axle shafts) to each wheel, plus a central propeller shaft that links the transmission to the rear differential. So driveshafts are absolutely relevant on this model.

On the 2019 Impreza, driveshafts do the heavy lifting of getting power from the transmission to the wheels. Up front and at the rear, constant-velocity (CV) shafts deliver smooth torque through tight steering angles and suspension travel. The centre propeller shaft (often just called the driveshaft) runs down the middle of the car to the rear diff, forming the backbone of Subaru’s Symmetrical AWD layout. The result is stable, predictable traction in Aussie and Kiwi conditions, from wet tarmac to gravel backroads.

There’s no fixed replacement interval for driveshafts, they’re a service-on-condition item. During regular servicing (every 10,000–15,000 km or six months is a handy check rhythm), a good technician will:

• Inspect CV boots for cracks, splits, or grease fling around the inner guard or underbody.
• Check for play in the CV joints and listen for clicking on full lock turns (classic worn outer CV sign).
• Road test for vibration under load or at certain speeds, which may point to a worn CV, prop shaft universal/constant joint, or centre support bearing.
• Look over the centre bearing rubber support and mounting hardware on the propeller shaft.

If a boot is torn but the joint’s still quiet and tight, a timely boot replacement and re-grease can save the shaft. Once water and grit get in, the joint wears quickly and a complete shaft is usually the smarter fix. For the propeller shaft, some Subaru assemblies have non-serviceable joints, if there’s play or a persistent shudder, replacement or a quality reconditioned unit is the go. Always match spline count and length, use new seals and a fresh axle nut, and torque everything to factory specs from the Subaru manual.

To keep things sweet between services: avoid torn boots by steering clear of sharp kerbs, check underbody after rough roads, and sort any clicking or vibration early before it takes out tyres, bearings, or diff mounts.

Does the 2019 Subaru Impreza actually have driveshafts?

Yes. Technical literature such as the Subaru Service Manual (2019MY) and Subaru Australia’s AWD specs confirm it has front and rear CV driveshafts and a central propeller shaft. AWD was standard in AU/NZ, so every local 2019 Impreza has the full set.

What are common signs the driveshafts need attention?

Clicking on tight turns, grease splatter near a wheel or underbody, vibration or shudder on acceleration or at highway speeds, and clunks when taking off or shifting from reverse to drive are the big giveaways. Any of these should prompt a proper inspection of CV joints, boots, and the centre prop shaft bearing.

How often should the CV boots and prop shaft be checked, and what might it cost?

Have them inspected at each service (about every 10,000–15,000 km). A boot-only repair is usually far cheaper than a full shaft. Complete CV shafts and prop shafts vary by brand and region, expect parts and labour to differ across Australia and New Zealand. A quick quote from a Subaru specialist will pin it down for your car’s VIN and spec.
