Wheel bearings make noise and CV axel leaking grease

I need help passing inspections , I don’t know what I’m looking for and where to go. I only need the wheel bearings cause they started to make a noise , and I wasn’t even aware my CV axel was leaking grease . This is all new to me . I really need help. If I fix these things I can pass inspections !! So please I’m putting my trust in this. It’s my only hope rn

This is the results I got from my failed inspections test

What do you need help with, are you going to do the work yourself?

At least both repairs go hand in hand, have to remove the cv axles to get at the wheel bearings.

The wheel bearings need a press to remove and install.

Which cv axle boots, there is an inner and outer boot on each one. I have to replace an outer boot, cost $16 for a new boot-clamps-snap ring at the Mercedes dealer.

this is really helpful thank you. I was thinking of doing the work myself but I work a lot so I don’t know when I’ll get to it. Where can I buy the parts? Mercedes dealer? Or website? Which ones can I trust?

FCP https://www.fcpeuro.com/Mercedes~Ben...&b=5&d=1043&v= is good.

Sometimes FCP doesnt have the part I want or my local MB parts dept is cheaper.

Without know your vin i cant check for the specific parts.

That bearing kit you posted looks like its for a RWD model. The front wheel bearings for a 4matic are sealed, like the one below listed for my 2010 4matic:

You have the same one as mine 204.081. That number is good to know when looking up parts diagrams.

Some other good things to know is you have the 486 Sports Suspension, and A89 latest transmission when choosing transmission fluid and filter.
