Subaru CV Axle Repairs

February 15th, 2024

Sometimes your Subaru might start making noises that just don't make much sense to the average driver. Hearing clicking from your front wheels, specifically when turning, can be concerning and send driver's into a frenzy trying to figure out what's going on. However, this is a sign that your CV axle might be in need of a repair or replacement. If you happen to notice grease collecting on the inside of your tires or on the edge of the tires, this is a sign that your CV axle likely needs to be serviced. When your CV axle fails, the lubricant leaks from the axle and you'll notice this around the tires. There's also a strong chance of feeling intense vibrations while you drive. If any of this sounds like an issue you've been having, it's time to have a technician look at your CV axles.

The CV axles in your ride are connected to the drivetrain through your front wheels. These axles allow front and all-wheel drive vehicles to power the front wheels so they can turn as you steer. The joints that help you accomplish this are protected by rubberized boots, which oftentimes can be torn or damaged by debris on the road, damage from a collision, or just regular wear and tear. When this damage occurs the lubricant helping it work seeps out, and eventually the axle will fail completely and cause further damage to your Subaru.

Things to Know About Your CV Axle

The lifespan of your CV axle is typically fairly long, withstanding 80,000 to 100,000 miles under regular driving conditions. If you begin hearing a loud, rhythmic clicking noise as you turn, it's a good sign the axle is failing. That noise is caused by the lubricant leaking in one of the CV axle joints, and as your CV axle is vital to your ride, having it properly serviced at your earliest opportunity is crucial. Driving with a failed CV axle is dangerous, as it can disconnect from either the wheel or differential and make you immediately stop, or the axle could break altogether. If a catastrophic failure happens while driving at high speeds this can become highly dangerous in an instant.

If your CV axle is perforated, then there will be no clicking, vibration or grinding when turning as the lubricant would remain in the joint. In this case it's safe to drive to a service center or repair shop for a replacement part or repair service. Sometimes just the boot itself needs to be replaced, which can extend the life of the original CV axle for thousands of additional miles if there is no damage. Having your axles regularly examined when you stop in for a regular service appointment can help relieve issues revolving around your CV axle.
