Parts for your 2012 Subaru Forester-Driveshafts

2012 Subaru Forester driveshafts – what they do and how to look after them

Driveshafts are absolutely relevant on the 2012 Subaru Forester. Technical references including the Subaru Factory Service Manual for the SH-series Forester (sections: Front Drive Shaft, Rear Drive Shaft and Propeller Shaft) and the Subaru parts catalogue for MY2012 list front and rear axle shafts (CV shafts) and a centre propeller shaft between the transmission and rear differential. So yes, this Forester runs multiple driveshafts as part of Subaru’s Symmetrical AWD layout.

What do they do? The front and rear CV driveshafts send power from the differentials to each wheel, flexing with suspension and steering movement via constant-velocity joints. The centre propeller shaft (often called the tailshaft) carries torque from the gearbox/transfer to the rear diff, typically with a centre support bearing and serviceable or sealed universal joints depending on build.

For servicing, it’s smart to inspect the shafts every service interval (around 12,500 km or 6 months for many AU/NZ schedules). Look for split CV boots, flung grease, cracked boots near the clamps, play in the joints, and any rumbling or vibration at speed. On the prop shaft, check the centre bearing rubber, U-joints for free play or binding, and listen for clunks on take-off or lift-off. Catching a torn boot early and replacing it with fresh grease can save a whole CV joint.

• Common symptoms: clicking on full lock, vibration under load or at motorway speeds, shudder on take-off, thumps when shifting, or visible grease spray.
• If a boot is torn, don’t wait—grit will chew out the joint fast.

When replacing, go for quality shafts with the correct ABS tone ring spec for the Forester’s wheel speed sensors. Renew axle nuts and stake them properly, and consider new oil seals if there’s any weep at the diff or hub. A prop shaft swap is straightforward—mark the flanges to keep balance orientation, torque the fasteners evenly, and make sure the centre bearing mount isn’t preloaded. A wheel alignment usually isn’t required for a straight axle swap, but if any suspension arms are disturbed, get it checked.

With gentle driving, sealed joints often last well past 150,000 km, but rough roads, water crossings and lifted suspension can shorten their life. Regular checks keep the Forester’s AWD smooth, quiet and reliable.

• Does the 2012 Subaru Forester have a centre driveshaft?
  Yes. Every 2012 Forester (manual or auto) has a centre propeller shaft linking the transmission/transfer to the rear differential as part of Subaru’s Symmetrical AWD.
• How often should CV boots and driveshafts be inspected?
  Inspect at each service (about every 12,500 km or 6 months). Replace boots as soon as they’re cracked or split
