Parts for your 2006 Subaru Impreza-Driveshafts

2006 Subaru Impreza Driveshafts

Yes, driveshafts are absolutely relevant and fitted to the 2006 Subaru Impreza. Technical sources that confirm this include the Subaru Factory Service Manual for MY2006 Impreza (Driveline/Axle — Propeller Shaft, Front Axle, Rear Axle), Subaru Australia’s 2006 Impreza brochure noting Symmetrical All-Wheel Drive as standard, and OEM parts catalogues listing a two-piece propeller shaft (rear driveshaft) plus front and rear CV drive shafts for this model. In Aussie and Kiwi markets, AWD is standard across the 2006 range, so every car runs a propeller shaft to the rear diff as well as CV shafts to each wheel.

On this Impreza, “driveshafts” can mean two things: the propeller shaft that sends torque to the rear differential, and the CV (constant velocity) axle shafts at each wheel that actually turn the tyres. Together they’re the backbone of Subaru’s Symmetrical AWD, helping deliver grippy, predictable handling on wet roads, gravel and long outback runs.

Servicing-wise, driveshafts don’t need constant fuss, but a quick check at each service goes a long way. Look for split CV boots, grease flung around the inner guards, and listen for clicking on tight turns (front CVs) or a dull thump and vibration under load (often prop shaft joints or carrier bearing). Surface rust isn’t a drama, torn boots and play in joints are.

• Inspect CV boots every 10,000–15,000 km or at each oil change, especially if the car sees gravel or coastal conditions.
• If a boot is torn, replace the boot promptly, if the joint’s noisy or gritty, replace the whole shaft.
• For the propeller shaft, check the centre carrier bearing and universal joints for play and noise, many are non-serviceable, so replacement of the assembly may be required.
• When removing shafts, mark flange orientations, use new seals and clips where specified, and torque to the workshop manual specs.

Common symptoms that call for action include shudder on take-off, vibration at highway speeds, clunks shifting from accel to decel, and grease spray around a wheel. A quality replacement shaft or a professionally rebuilt unit, fitted with new seals, will restore the trademark Subaru smoothness. For those doing big kilometres or towing, preventative boot replacement and regular checks under the bonnet and underbody will save a heap of hassle.

How can someone tell if their 2006 Impreza’s driveshafts are on the way out?

Clicking on full lock (especially when turning right or left under throttle) points to a front CV. A rhythmic vibration that rises with speed often comes from the propeller shaft or its carrier bearing. Grease sprayed near a wheel or along the underbody usually means a split CV boot. Any clunk when shifting from accelerate to decelerate is another red flag.

Do the driveshafts have a set replacement interval?

No fixed interval. Many last well beyond 200,000 km if boots stay intact. Harsh roads, lowered suspension or big torque loads can shorten life. Inspect at every service and replace at the first sign of joint play, noise, torn boots or vibration to avoid collateral damage.

Is it safe to keep driving with a torn CV boot?

Not for long. Once the boot tears, grease escapes and grit gets in. The joint can fail quickly, leading to noise, vibration and potential loss of drive. If the boot is caught early, a boot kit may save the shaft, leave it and you’ll likely need a complete driveshaft.
