CV Boot Torn

Hi All,

I did 4 brakes on my 2019 S560 this weekend. While the break job went off without any issues, I did notice a lot of grease on the rear of my pass side front wheel.
Further inspection shows this......
The boot split and spilled its grease....
Car has 110K miles on it.
I am thinking replace the half axle?
Is it called a drive shaft?
Replace boot?
What do you guys think?

If it were mine, I'd replace the CV axle shaft for piece of mind.

Do you hear any clicking noises when turning?

No clunking noises, I bet this just happened.
Would you do both sides, or just one?
is this a beast of a Job?

Haven't had to do this on my S class but if it's similar to most other cars, plan on a couple hours.

I DIY everything and have just about every tool needed so while I say "jump in", others may not.

Many shops will try to tell you need to replace the shaft, to make more money.
but a good mechanic should be able to replace just the boot or have a specialized shaft replace the boot only. Should be 200-400 or so.

Labor to take out the axle and replace the boot is same as just putting in a new axle. Almost certainly some amount of dirt and grit has gotten into the joint and will eventually ruin it, so you really should replace the entire axle. Further more, if the boot on one end of the axle has failed the one on the other end may also be close to failing and you wouldn't want to do this twice.

The axles themselves aren't terribly expensive ...https://www.rockauto.com/en/moreinfo...t=2288&jsn=693

OP I'd have your OEM axle with fresh boots and grease over an aftermarket C/V axle every day of the week and twice on Sunday.

If it is not clicking in sharp turns with lots of steering lock it is alive. Grease is thrown out via centrifugal force and dirt doesn't get in there until the boot is wide open.

Easy? Not in particular. DIY-able for those of us with a hoist and a sense of adventure. I'm too old to do such things on stands.
