The length of the Mercedes Axels are measured with the Axles off of the Car and the Joints compressed fully inwards then the length is measured.

When I got Cardone rebuilt axles back in 2007 they cam with a new Bolt, Washer and I beleve a tube spacer and that is the parts that go through the Hub to hold the Hub end of the Axle in.

On the Cardon Axles I suppose I could have exchanged them on the life time warranty but I chose not to. Partly because I bought them fro Chief's Auto Parts wich was sold to Oreilly's Auto Parts and paper work dissapears in my house.

When you remover your Axle you should make sure that the Spacers (if there is any) stay on with the Differential.

If when you get the replacement axles and stick them in the Differential the original spacers (if there was any) do not produce the proper fit then you need to get a different thickness of Spacer. Ask Stratch how to determine what thickness you need.

I have had Cardon rebuilt Axles on My Car since 2007. No issues except that the stock style Axle Boots started to crack after 5 years of low milage use. When I removed the old Boots there was nothing on the Boot except some numbers that did not match any specific part number or helped me determine where the Boots were made.

Anyway I replaced the Boots with Dorman Universal Boots and that was a few years ago with no other issues.

You will have to ask someone how long their CVJ Axel Boots have held up.
