Parts for your 2006 Subaru Forester-Cv joint

2006 Subaru Forester CV joint — what it does and how to look after it

Multiple technical references confirm the 2006 Subaru Forester (SG, AWD) is fitted with constant velocity (CV) joints front and rear. This is documented in the Subaru Factory Service Manual for 2006 Forester (Drive Shaft/Front Axle and Rear Axle sections), the Subaru Genuine Parts Catalogue for SG models (front drive shaft and rear halfshaft diagrams), and mainstream application data from driveline manufacturers such as GKN/Löbro. So a CV-joint is absolutely relevant on this vehicle.

On this Forester, the outer joints are Birfield/Rzeppa style to steer smoothly, while the inner joints are plunge/DOJ types that slide in and out as the suspension travels. Together they let the all-wheel-drive system put power down through tight corners without vibration, binding, or undue wear.

As part of routine servicing, the smart move is to keep an eye on the rubber boots and any hint of grease spray around the inner guards or underbody. Once a boot splits, the joint can fling out grease and suck in grit, which quickly chews the bearing surfaces. Catching a perished boot early and rebooting with the correct moly CV grease is cheaper than replacing a whole axle.

• Common signs to watch for:
  • Clicking or clacking on tight turns (outer joint wear).
  • Shudder under load or on take-off (inner joint or excessive play).
  • Grease mist on wheels or chassis near the boot area.

When replacement is needed, many owners prefer rebooting and regreasing the original Subaru shafts if the joint surfaces are still tidy. Genuine or quality OE-equivalent axles typically behave better than cheapies that can introduce vibrations or ABS quirks. If swapping a full shaft, match the transmission type and ABS tone ring spec, and always torque the axle nut to the factory value from the Subaru manual. Refit with a new split pin or spring pin where required, and avoid hammering on stubs or hubs to protect bearings.

Service tips that make life easier:

• Inspect CV boots every service or 10,000 km—especially after gravel-road trips.
• Use the specified high-moly CV grease and fresh clamps when rebooting.
• After axle work, recheck wheel bearing play and road test for noise on full lock.

Does a 2006 Subaru Forester have CV joints front and rear?

Yes. The SG Forester uses CV joints on the front drive shafts and on the rear halfshafts. This layout is shown in Subaru’s service manual and parts catalogue, and it’s standard fare for Subaru’s AWD driveline on this model year.

What are the tell-tale signs a CV joint or boot needs attention?

Grease flicked around the inner guard or wheel area points to a split boot. Clicking on full-lock turns usually means an outer joint is worn, while a shudder or vibration under acceleration can hint at inner joint play. Get onto it early—rebooting a good joint is far cheaper than replacing an axle after grit gets in.

Should they replace the whole axle or just reboot the joint?

If the joint surfaces are still smooth and quiet, a reboot with the correct grease is a top-value fix. If there’s clicking, blueing, pitting, or heavy play, a quality OE or OE-equivalent complete shaft is the better bet. Cheap axles can introduce vibration, so it pays to choose carefully.
