Parts for your 2011 Subaru Impreza-Cv boots

2011 Subaru Impreza CV boots — what they do and when to replace them

Technical sources confirm the 2011 Subaru Impreza is fitted with CV boots on its front and rear drive shafts. Subaru Factory Service Manual (2011 Impreza GE/GH/GR/GV – Drive Shaft section), the Subaru Electronic Parts Catalogue (listing inner/outer boot kits for the model line), and independent manuals such as the Haynes Repair Manual for Subaru Impreza 2008–2014 all detail inspection and replacement of these boots. So yes, CV boots are relevant to servicing a 2011 Subaru Impreza.

On this AWD Impreza, each driveshaft uses constant velocity joints protected by flexible rubber boots, packed with moly grease. Those boots keep the joint lubricated and seal out water, road grit, and mud. When a boot cracks or splits, grease flings out and contaminants rush in, quickly chewing out the joint and leading to that classic clicking on turns. Replacing a worn boot early is miles cheaper than a full shaft or CV joint replacement.

As part of regular servicing, it’s smart to ask for a CV boot inspection every 10–15,000 kilometres, or any time the front undertray comes off. A quick look behind each wheel and at the inner boots near the transmission can catch early weeping or fine cracking. After beach runs, gravel roads, or water crossings, give them another once-over.

• Common signs it’s time: grease spray on the inside of the wheel or guard, rubber cracking, a burning grease smell after a drive, clicking on turns, or vibration on take-off.
• Front boots usually fail first (more steering angle and heat), but the rears age as well—don’t ignore them.

When replacing, quality matters. Use a proper Subaru-spec boot kit with new stainless bands and the correct molybdenum disulphide CV grease. Clean the joint thoroughly, repack to the specified quantity in the service manual, and fit the boot so ribs sit naturally without twisting. Single-use clamps must be replaced and crimped with the right tool to avoid leaks. If the joint’s already noisy or gritty, a complete driveshaft may be the better call.

After reassembly, the axle nut should be torqued to the Subaru specification and staked correctly. A wheel alignment isn’t typically required unless suspension components were disturbed. Keeping on top of CV boots is simple preventative maintenance that helps the Impreza stay quiet, smooth, and reliable on Aussie and Kiwi roads.

Popular questions

Q: How often should CV boots be checked on a 2011 Subaru Impreza?

They’re best checked at every routine service (about every 10–15,000 km) and after harsh use like gravel, muddy tracks, or beach driving. Regular inspections spot small cracks or weeping grease before the joint is damaged.

Q: Can a split CV boot be repaired temporarily on the Impreza?

Universal “split” boots can get someone out of trouble, but they don’t seal as reliably or last as long. The preferred fix is removing the shaft, properly cleaning and repacking the joint, and installing a quality boot kit with new clamps.

Q: Do rear CV boots wear out as often as the fronts?

Front boots tend to fail first due to steering angles, heat, and road spray. That said, the rear boots age and can crack over time—especially on higher-kilometre cars or vehicles used off-road—so they deserve the same inspection routine.
