Parts for your 2007 Subaru Impreza-Cv boots

2007 Subaru Impreza CV boots — what they do and how to look after them

Based on the Subaru Impreza 2007 Factory Service Manual (Driveline/Axle section) and the Subaru Electronic Parts Catalogue for MY2007, the 2007 Subaru Impreza uses constant velocity (CV) joints on the front drive shafts (and rear as well on AWD models). Each joint is sealed by a rubber CV boot with clamps and specified CV grease. Haynes’ Subaru Impreza 2002–2011 manual also details inspection and replacement of front and rear CV boots. So yes — CV boots are absolutely relevant and fitted to the 2007 Subaru Impreza.

On a 2007 Impreza, CV boots do a simple but vital job: they keep thick moly grease in and water, sand, and grit out of the CV joints. Those joints let the axles transfer drive smoothly while the wheels steer and the suspension moves — crucial on an AWD Subaru that sees plenty of wet, dusty, or corrugated Kiwi and Aussie roads. Each front axle has an inner and outer boot, AWD models also have CV boots on the rear axle shafts. When the rubber boots age, crack, or the clamps loosen, grease flings out, contaminants get in, and the joint can wear quickly, leading to clicking on tight turns, vibration under load, or even joint failure.

There’s no fixed replacement interval for CV boots in the factory schedule, but the service literature calls for regular inspection. A good rule of thumb locally is to check them at every service or at least every 10,000–15,000 kilometres. Look for splits, weeping grease at the clamp edges, or a messy spray of grease on the inner guard or subframe. Catching a split early means a straightforward boot-and-grease job rather than a full driveshaft replacement.

When replacing, use OE-quality boots, the correct CV joint grease, and proper ear-type or stainless clamps crimped with the right tool. If one boot has failed, consider the condition of its mate on the same shaft, as they’ve lived the same life. On reassembly, follow the factory manual for axle removal/refit steps and torque specs for the axle nut and suspension hardware. Aftermarket “stretch” boots can work in a pinch, but for long-term durability on an Impreza, formed boots with correct clamps are the safer bet.

• Tell-tales of trouble: clicking on turns, shudder on acceleration, or visible grease spray.
• Best practice: inspect at each service, especially if the car sees gravel, beach runs, or lots of city steering.
• Act early: replacing a boot is cheaper than replacing a noisy CV joint or complete shaft.

FAQs

How often should CV boots be checked on a 2007 Subaru Impreza?
They should be visually inspected at every regular service, or at least every 10,000–15,000 kilometres. If the car regularly drives on gravel, through mud, or in heavy rain, check more often. Early detection of small splits or weeping clamps prevents costly joint damage.

What are the common signs a CV boot has failed?
Grease splattered around the inside of the wheel, control arms, or subframe is the big giveaway. You may also notice a cracking or clicking noise on tight turns if the outer joint has been contaminated. Any visible splits, loose clamps, or perished rubber mean it’s time for attention.

Can a split CV boot be replaced without changing the whole axle?
Yes. If the joint hasn’t run dry or ingested grit for long, a new boot, fresh moly grease, and proper clamps will sort it. If there’s clicking, roughness, or excessive play, the joint (or complete shaft) may need replacement — a technician can assess this during disassembly.
