Need to replace RR air shock...
 

I need to replace the RR shock in my wifes E320. Does anyone have part number and can I replace it with a shock with out the reservoir tank (arrnot)? I'm only going to do the one side at this time.

you don't need expansion tank. yes you can just do one but maybe arnott will cut you a price if you replace in pairs. this must be a wagon correct? Wait, we are talking about air bellow and not the actual shock??? just type in w211 rear air bellow/shock assembly.... not sure on exact part number without vin!

Sorry I meant the air spring! And it is not a wagon.

No matter what you want, your choice is either MB, or Arnott.
Both will match parts to your VIN and both will recommend replacement in pairs.

wait, your 2003 E320 has air ride?

any which case, you might find post #5 useful..
