Hi guys, need help! Got 08 63MLAMG got front left Axle that is really tight on the joint barely can bend it side that goes in to the differential. At 50 mpg i had a noise coming from the front of the car i couldnt figure out what it was. i guessing this is my problem because its really tight.
My Axle part # is A 1643300701.
My question, is it ok to use Axle from any model like ML350 ML550 i see alot of diffrent part numbers but they all fit W164.
Can i use A1643300801 or A1643302301
Or i only have to use same part # i have? Thank you in advance for any help.

 

No you cannot use any other axle shaft.

 

Thank you Maj. Dundee.I wonder what is the difference between them, its the same chassis. I know all W163 used the same Axles.

 

I have no true reason why, maybe they are beefier .
