Parts for your 2007 Subaru Impreza-Driveshafts

2007 Subaru Impreza driveshafts — what they do and how to look after them

Yes, driveshafts are absolutely relevant and fitted to the 2007 Subaru Impreza. Technical sources including the Subaru Impreza 2007MY Service Manual (Driveline/Axle — Front Drive Shaft, Propeller Shaft sections), Subaru Australia’s Symmetrical AWD technical literature, and the Haynes Repair Manual for Subaru Impreza 2001–2011 confirm the vehicle uses front driveshafts (CV axles) and, on AWD variants sold in Australia and New Zealand, a propeller shaft to the rear differential. That’s the backbone of Subaru’s Symmetrical AWD layout.

On a 2007 Impreza, the driveshafts do the hard yakka of sending engine torque to the wheels while dealing with suspension movement and, at the front, steering angles. The front CV axles connect the transaxle to the hubs, using CV joints to keep things smooth through bumps and turns. The centre propeller shaft runs from the transmission to the rear diff, keeping the AWD system permanently engaged for balanced grip.

Good driveshafts mean quiet, vibration-free motoring. When they’re tired, they’ll tell you: clicking on tight turns, shudder on take-off, a buzz between 80–100 km/h, or grease flung around a torn CV boot. On the prop shaft, a failing centre bearing or worn joints can add a deep vibration under load.

As part of routine servicing (every 10,000–15,000 kilometres or at regular service intervals), it’s smart to:

• Inspect CV boots for cracks or splits, and clean/replace clamps if weeping.
• Check for play, clicks or notchiness in CV joints, listen on full-lock low-speed turns.
• Spin and feel the propeller shaft centre bearing, look for perished rubber or roughness.
• Verify flange bolts are tight and there’s no fresh oil at axle or diff seals.
• Keep tyres matched in size and wear across all four corners to protect the AWD driveline.

If a boot is torn, act quickly—replacing just the boot and grease early can save the whole axle. When an axle or prop shaft is due, go for quality OEM-equivalent parts. Replace the front axle nut with a new staked nut, align any prop shaft phasing marks, and torque everything properly. After work, a road test for vibration and a quick alignment check are good practice. For many Subaru prop shafts, the universal joints are non‑serviceable, a complete shaft or specialist rebuild is the go if they’re worn.

How long do 2007 Impreza driveshafts typically last?

With intact boots and regular servicing, CV axles often run well past 150,000–250,000 kilometres. The propeller shaft usually lasts similar or longer, but harsh roads, mismatched tyres, and leaks can shorten life. Early attention to boot damage pays for itself.

Can you drive with a torn CV boot?

Not for long without risk. A split boot throws out grease and lets grit in, rapidly wearing the CV joint. If caught early, a boot kit and fresh grease may save the axle. If it’s been noisy or driven for a while, plan on a complete axle replacement.

What does driveshaft replacement cost in AU/NZ?

Ballpark figures vary by brand and labour rates: front CV axle supply and fit is often a few hundred dollars per side, while a complete propeller shaft can run higher. Quality parts and proper installation matter more than chasing the cheapest option—vibration from poor axles isn’t worth the hassle.
