CV! CV! CV!

Sounds like your CV boot has split. Get it checked ASAP as it may still be rescueable!

what a cv boot ? how much will that cost to repair??

The CV (constant velocity) is a universal joint that allows the drive shaft to move with the suspension. There are 2 on each side, an inboard and outboard. The inboard is on the gearbox casing and rarely gives problems. The outboard is just behind the wheel bearing and on a FWD car has to flex left/right as well as up down.

If only the boot needs changing it could be around £40. If it needs the CV changing too it will cost more for the parts, labour should be around the same price.

As you can see a lot of moving parts - so having them cased in grease keeps them healthy and quiet. When they lose their grease they become noisey and eventually will fail.

And in most cases you'll need to replace them in pairs
