2009 Subaru Forester CV Boots — What They Do and When to Replace

CV boots are absolutely used on the 2009 Subaru Forester. Technical sources including the Subaru Factory Service Manual (2009MY Forester, SH chassis – Drive Shaft/Front Axle and Rear Axle sections) and the Subaru genuine parts catalogue (boot kit listings for front outer/inner and rear axle boots) confirm the model’s front and rear drive shafts use constant velocity joints protected by rubber boots. So yes—CV boots are relevant to every 2009 Forester, regardless of trim.

On this all-wheel-drive Forester, each front axle has an outer CV joint for steering and an inner DOJ (double offset joint) for plunge movement, the rear axles also use CV joints. The boots are the ribbed rubber bellows that keep special moly grease in and dust, water, and grit out. If a boot splits, grease flings onto the inner guard and suspension, the joint runs dry, and wear accelerates fast—often leading to that classic clicking on turns.

As part of regular servicing of your 2009-subaru-forester cv-boots, a quick look goes a long way. At each service or about every 10,000–15,000 km, check for cracks in the bellows, loose clamps, or fresh grease spray. Catching a small split early usually means a simple boot kit with fresh grease and clamps, rather than a whole axle replacement.

When replacing a CV boot, quality matters. A proper boot kit includes the correct boot profile, stainless clamps, and the right spec grease. Many techs avoid “split” or glue-on boots on Subarus, they’re a stopgap at best. A full boot replacement with the joint cleaned and repacked is the reliable fix. After refitting, ensure clamps are seated, the boot isn’t twisted at full lock or full droop, and the area is wiped clean so any new leaks are obvious later.

Driving habit and environment affect life. City kerbs, gravel roads, and lots of steering lock speed up degradation. If there’s clicking when turning, vibration on throttle, or a rhythmic clunk, the joint may already be worn—at that point a complete axle can be the smarter spend. Keeping the cv-boots in good nick protects the joints, keeps the AWD Forester smooth and quiet, and saves a bundle down the track.

• Tell-tales to watch: grease spray near the hub, perished rubber, loose or missing clamps, clicking on turns.
• Good practice: inspect every service, clean and re-grease if boots are off, and use proper boot kits over quick-fix split boots.

Popular questions about 2009 Subaru Forester CV boots

How long do CV boots last on a 2009 Subaru Forester?
With gentle driving and sealed roads, it’s common to see 100,000 km or more. In Aussie and Kiwi conditions with heat, gravel, and full-lock parking, they can age sooner. Regular inspections during routine servicing catch cracks early and extend joint life.

Can a torn CV boot be replaced without changing the whole axle?
Yes—if the joint hasn’t run dry or picked up grit. A proper boot kit, clean-out, and fresh grease will sort it. If there’s clicking or visible pitting in the joint, replacing the complete axle is usually the better long-term repair.

What are the signs a CV boot has failed on a Forester?
Look for grease flung around the inside of the wheel or lower control arm, a split in the boot’s bellows, or a loose clamp. If the joint’s already worn, you’ll hear a clicking on turns (outer joint) or feel vibration under load (often inner joint).
