Please forgive me as im new to the mercedes world. I typically work on my truck and replace everything myself. With this fancy vehicle, im hesitant to do so. My girlfriend has a 2015 CLA 250 and the driver side cv axle outer boot has a tear in it. The OEM axle will cost me somewhere around $900 if purchasing from mercedes. Is there anyone else that makes a quality cv axle thats not as costly? Any help would be greatly appreciated!!
