Parts for your 1999 Subaru Forester-Cv boots

1999 Subaru Forester CV boots — what they do and when to replace them

CV boots are absolutely used on the 1999 Subaru Forester. The Subaru Factory Service Manual for the SF-series (MY1999) details front and rear drive shafts with inner and outer constant velocity joints protected by rubber boots, and Subaru’s genuine parts catalogue lists specific boot kits for those shafts. Workshop references like Haynes and Gregory’s also cover boot inspection and replacement for this generation, confirming they’re standard fitment on both front and rear axles due to the Forester’s full-time AWD and independent suspension.

On this Forester, the CV boots are tough, ribbed rubber covers that keep high-moly grease inside the joints and grit, water, and dust out. The outer boots guard the Rzeppa-style joints that handle steering angles up front, while the inner boots cover the DOJ-type joints that manage plunge as the suspension moves. If a boot splits, grease flings out and contaminants sneak in, which can quickly chew out the joint—cue the classic clicking on turns and shudder under load.

For everyday servicing in Australia and New Zealand, a quick look at the CV boots at each service interval (or every 10,000–15,000 km) is a smart move—especially if the Forester spends time on gravel roads, in coastal spray, or towing. Light surface cracking in the rubber is an early warning, wet, flung grease around the inner rim of the wheel or control arms means it’s time to act.

Catch a split early and a boot-only repair with fresh grease and new clamps usually saves the joint. If there’s already noise or roughness, it’s often better value to replace the complete shaft assembly. When fitting new boots, use the correct lithium-moly CV grease, new clamps tightened to spec, and ensure the boot isn’t twisted at full lock or full droop. A wheel alignment isn’t generally required for a shaft swap on this model, but it’s wise to recheck fastener torque after a short drive and keep an eye out for any new leaks or vibrations.

• Typical signs to watch: grease spray near the wheel, cracking or splits in the boot, clicking on turns, vibration under acceleration.
• Care tips: inspect at each service, clean away built-up mud, and address any clamp looseness before it escalates.

Popular questions about 1999 Subaru Forester CV boots

How often should CV boots be replaced on a 1999 Forester?
There’s no fixed replacement interval, boots are serviced on condition. With regular checks, many last well over 100,000 km. Inspect them at each service, and more often if driving on gravel or beach access roads. Replace at the first sign of cracking, tearing, or grease leakage.

Can a torn CV boot be repaired or must the whole axle be replaced?
If the joint hasn’t run dry or ingested grit, a new boot kit with fresh moly grease is fine. If there’s clicking on turns, blueing, rust-coloured grease, or noticeable play, a complete shaft is usually the more economical and reliable fix.

What symptoms point to a failing CV joint on this model?
Common giveaways are a rhythmic click or clack while turning and accelerating, vibration under load, and grease splatter inside the wheel or along the suspension. Address it quickly to avoid collateral damage to wheel bearings and brakes.
