need to prepare new washers for differential fluid change?
For W124 rear differential fluid change, must I prepare two new washers?
Or is it OK to re-use existing washers?

Differential Washers
Hi,---- The answer to your question is NO. I have owned a 91 & presently a 95 w124 that I have done differential service on. The fill & drain plugs are tapered pipe thread which do not require a sealing washer. They are 14 MM HEX size. You will need a 1/2" drive hex 14MM & a breaker bar to "crack them loose", sometimes they "are in there". Make sure you remove the fill plug FIRST, if you drain it & can't remove the fill plug, you have a " Big Problem ". Good Luck ,------ Ray

Good advice from Ray - especially on removing the fill plug first.
It's also a good idea to either wrap teflon tape on the threads or treat them with neversieze to prevent them from rusting on in the future.

Excellent advise from above. Make sure you have a breaker bar that is plenty long enough.

It also helps to spray them with a penetrating oil a few times x a few days before you intend to remove them. By doing this I didn't need a breaker bar or have any trouble removing mine after 12+ years becoming stuck.
