Parts for your 2011 Subaru Forester-Cv boots

2011 Subaru Forester CV-boots: purpose, care and when to replace

Referencing technical sources: the Subaru Forester 2011 Service Manual (Drive Shaft/Front and Rear Axle sections) and the Subaru Genuine Parts Catalogue for MY2011 Forester both specify front and rear constant-velocity (CV) joints with protective rubber boots. That confirms cv-boots are fitted and very relevant on the 2011 Subaru Forester.

On a 2011 Subaru Forester, cv-boots are the flexible rubber sleeves that seal each CV joint on the front driveshafts and rear axle shafts. Their job is simple but critical: keep high-moly grease in, and water, grit and road muck out. Because the Forester is AWD and often sees gravel, beach runs and the odd track, these boots cop a fair hiding. If a boot splits, grease flings onto the inside of the wheel and suspension, the joint runs dry, and wear ramps up quickly—cue clicking on turns (outer joint) or shudder under load (inner joint).

As part of routine servicing, it’s smart to have the cv-boots inspected every 10,000–15,000 kilometres, or at each service if the car sees a lot of corrugations or off-road use. A quick look for fine cracks, greasy spray, torn clamps or perished rubber can save a full axle replacement later. If a boot is just cracked or split but the joint hasn’t ingested grit or water, a boot-only replacement with fresh molybdenum CV grease and new clamps usually does the trick and keeps costs down.

When replacing a cv-boot, using the correct boot kit for the SH-chassis Forester matters, as does the proper clamp tool so the bands are tight and even. After refitting, the axle nut should be torqued to the factory spec and the wheel alignment checked if any suspension fasteners were disturbed. If the joint is already noisy, pitted, or has been run dry, it’s better value to fit a complete driveshaft assembly rather than gamble on a boot alone.

Drivers who regularly tow, launch boats, or tackle mud and sand should rinse the underbody and book more frequent inspections—salt and grit are boot killers. Treated early, a $50–$150 boot kit and a bit of labour keeps the Forester’s driveline quiet, smooth, and ready for the next mission.

Popular questions about 2011 Subaru Forester cv-boots

How can someone tell if a cv-boot on a 2011 Forester is torn?
Common giveaways are grease splattered around the inside of the wheel or along the suspension arm, a visible split or missing clamp on the boot, and dirt stuck to wet grease. If left too long, a clicking noise on tight turns often follows, meaning the joint has started to wear.

Can just the cv-boot be replaced, or does the whole driveshaft need swapping?
If the boot has recently split and the joint hasn’t taken in grit or water, a boot-only replacement with fresh grease is fine. If there’s clicking, roughness, rust-coloured grease, or excessive play, a complete shaft is the safer, longer-lasting fix.

How often should cv-boots be checked on a Forester used on gravel or off-road?
Have them inspected at every service, and sooner after harsh trips. Frequent gravel, beach work, or mud warrants a quick look after each outing—catching a small crack early avoids joint damage.
