Parts for your 2006 Subaru Forester-Driveshafts

2006 Subaru Forester driveshafts

Driveshafts are absolutely used on the 2006 Subaru Forester. Technical sources including the Subaru Factory Service Manual for the SG-series (Driveline/Axle sections: Propeller Shaft, Front & Rear Drive Shafts), the Subaru Electronic Parts Catalogue, and common workshop manuals for 2003–2008 Forester models all specify a longitudinal propeller shaft to the rear differential plus CV-type front and rear drive shafts. That means driveshafts are directly relevant to this model—no question.

On a 2006 Forester, the centre propeller shaft sends drive from the gearbox/transfer assembly to the rear diff, while each axle uses CV-jointed drive shafts to transfer torque to the wheels. In everyday terms, these shafts are what turn engine power into movement at all four corners, keeping the Subaru’s AWD grip working whether it’s on wet tarmac or a gravel back road.

As part of routine servicing, it’s smart to check the driveshafts every 15,000 km or 12 months. Look for split CV boots, thrown grease, or perished rubber at the centre support bearing on the prop shaft. Spin and flex the shafts by hand with the vehicle safely supported—any notchiness, play or visible cracks in boots calls for attention. A light click on tight low-speed turns suggests a worn outer CV, while a vibration or shudder under load (often 60–80 km/h) can point to a tired universal joint, out-of-phase prop shaft, or a failing centre bearing.

If replacing components, mark flange positions so the prop shaft goes back in phase, and use new self-locking nuts and clips where specified. Keep the mating faces clean, torque to spec from the service manual, and don’t forget to re-check the rear diff companion flange for play. For CV shafts, a quality boot kit can save a good joint if caught early, once the joint clicks, a complete shaft is usually the better fix. After any driveline work, a short road test to confirm no vibration or binding is a must.

• Watch for grease spray near a wheel or underbody—often a torn CV boot.
• Listen for clicking on turns, thumps on take-off, or steady-speed vibration.
• Replace damaged boots promptly to avoid destroying a serviceable CV joint.

Popular questions about 2006 Subaru Forester driveshafts

How long do the driveshafts and CV joints typically last?
With normal use, many Forester CV shafts last well over 150,000 km, and the prop shaft can go much farther. Lifespan depends on boot condition and road grime—boots that stay intact keep grease in and water out, dramatically extending life. Regular inspections during routine servicing make the biggest difference.

Can someone keep driving with a torn CV boot?
It’s not a great idea. Once the boot splits, grease escapes and grit gets in, quickly wearing the joint. If the joint hasn’t started clicking yet, a prompt boot replacement can save the shaft. If there’s already noise on turns, a complete CV shaft is usually required.

What causes a vibration around 60–80 km/h under load?
On this model it’s commonly a worn universal joint, a failing centre support bearing, or an out-of-balance/incorrectly phased prop shaft. Less often, a deformed tyre or engine mount issue can mimic the symptom. A workshop can check shaft play, bearing condition, and phasing marks to pinpoint the cause.
