Parts for your 2023 Subaru Impreza-Driveshafts

2023 Subaru Impreza driveshafts: what they do and how to look after them

Based on factory service information for the GK/GT Impreza platform (2017–2023) and Subaru AU/NZ specifications listing Symmetrical All‑Wheel Drive as standard, the 2023 Subaru Impreza is fitted with a centre propeller shaft (driveshaft) to the rear differential, along with front and rear CV half‑shafts at each wheel. So yes—driveshafts are very much relevant on this model.

On the 2023 Impreza, the centre driveshaft carries torque from the transmission’s transfer section to the rear differential, letting the AWD system share grip front to rear. The four CV half‑shafts then deliver that torque to each wheel while allowing steering and suspension movement. It all works together to keep things smooth, balanced and predictable on wet bitumen, gravel and the odd muddy verge.

As part of regular servicing, a few simple checks go a long way:

• Inspect CV boots for splits or grease fling, replace any damaged boots before the joint runs dry.
• Check for play in the front and rear CV joints, and listen for clicking on tight turns (front) or shudder on take‑off (inner CV).
• Look over the prop shaft centre support bearing and feel for vibration at 60–90 km/h that rises with speed.
• Check prop shaft flange bolts for tightness and rust scale, and watch for oil leaks at the transmission/diff that can contaminate rubber components.

Subaru’s OE prop shafts often use staked, non‑serviceable uni joints, so if a joint is worn the complete assembly is typically replaced. When swapping a prop shaft, mark the flanges to preserve balance, torque the hardware correctly, and position the centre bearing as specified to avoid preload and drone. For CV half‑shafts, use quality replacements, renew axle nuts and seals, and torque the axle nut to spec to protect the hub bearing.

Service interval wise, a visual driveline check every 12 months or 15,000 km is a smart play, with extra attention after beach runs or gravel touring. Keeping tyre sizes and wear matched across all four corners also reduces stress on the AWD driveline and helps the driveshafts live a long, quiet life.

Popular questions

Does the 2023 Subaru Impreza have a driveshaft?
Yes. With Subaru’s Symmetrical AWD standard in AU/NZ, it has a centre propeller shaft to the rear differential plus four CV half‑shafts, one to each wheel.

How long do the driveshafts and CV joints usually last?
With intact boots and sensible driving, many see 150,000–250,000 km or more. Boots and clamps tend to fail before joints do, catching a split boot early can save the shaft.

What symptoms point to a driveshaft issue?
Clicking on tight turns hints at a front outer CV. A rumble or vibration that tracks road speed can point to the prop shaft or its centre bearing. Shudder on take‑off often suggests an inner CV joint. Any of these warrant a proper inspection.
