A torn CV boot is a split in the rubber cover over a CV joint on your axle. Get it fixed soon, because grease leaks out and dirt gets in.
The boot keeps the joint lubricated and keeps out dirt and road grit.
To spot a tear, look at the inside of your front wheels. Grease sprayed there points to a torn boot. You might also see a cut or cracks in the rubber. One Canadian mechanic service suggests checking the boots every 30,000 to 50,000 kilometres.
Timing matters. Catch the tear early, and the fix can be a new boot. The shop cleans the joint, packs in fresh grease and clamps on a new boot. That only works if the joint is still good.
Wait too long, and grit wears the joint out. Then a boot alone won’t fix it, and you’ll likely need a whole axle. Driving on a bad boot can be dangerous.
Have the boots checked at your next service. For prices, read our guide to CV axle replacement cost in Vancouver.
