2009 Subaru Impreza CV Boots — Purpose, care, and when to replace

Based on factory documentation and parts listings, CV boots are absolutely used on the 2009 Subaru Impreza. The Subaru Impreza/WRX 2008–2011 Service Manual (Front and Rear Axle sections) specifies inner and outer boots on each driveshaft, and Subaru’s parts catalog lists front drive shaft boot kits (e.g., outer 28323FG000 and inner 28323FG010) for GE/GH chassis models. General repair guides such as the Haynes Subaru Impreza 2001–2011 manual also outline CV boot inspection and replacement. So yes, the 2009 Impreza runs CV boots on its front and rear axles to protect the constant-velocity joints.

On this model, those rubber boots sit over the CV joints and keep high-moly grease in while keeping water, grit, and road muck out. With Subaru’s Symmetrical AWD doing the hard yards, the CVs articulate and spin under load all day long, and the boots are the unsung heroes that stop the joints from running dry and wearing out prematurely.

For routine servicing, it’s smart to check the boots at every oil change or at least every 10,000–15,000 km. A quick look for splits, perishing, loose clamps, or grease sling on the inside of the wheels can save a lot of coin. Once a boot tears, grease escapes and contaminants get in, left too long, that can chew out a joint and turn a simple boot job into a full driveshaft or CV replacement.

Replacement is straightforward for a trained tech: remove the shaft, clean the joint, repack with the specified CV grease, slide on a quality boot, and clamp it to spec. Genuine-style kits with the right grease and clamps tend to outlast cheap alternatives, which matters on Aussie and Kiwi roads where weather and road grime can be harsh. If a joint’s already noisy (clicking on turns or clunks on take-off), a new boot won’t fix it—at that point, a reconditioned or new shaft is the go.

• Tell-tales of trouble: grease flung around the guard or wheel, visible cracks, clicking on full lock, vibration on acceleration.
• Good habits: keep an eye at tyre rotations, wash off heavy mud after off-road detours, and replace boots in pairs on the same axle if ageing is similar.

Popular questions about 2009 Subaru Impreza CV boots

How often should CV boots be inspected on a 2009 Impreza?
Most workshops give them a look at every service. As a rule of thumb, every 10,000–15,000 km or at each tyre rotation works well. More frequent checks make sense if the car sees gravel, coastal roads, or off-bitumen trips.

What are the symptoms of a torn CV boot?
Grease spattered on the inside of the wheel or guard, visible splits or loose clamps, and eventually clicking on tight turns as the joint wears. If clicking’s started, the joint may already be damaged.

Can just the boot be replaced, or does the whole axle need doing?
If the boot has torn but the joint is still quiet and free of play, a boot-and-grease service is fine. If the joint clicks, grinds, or has excessive play, a complete driveshaft or CV joint replacement is the better fix.
