Hello Mark,

Welcome to the forum, I could not tell you what year that was, but I can tell you how you may discover the part providing it is sold separately?

What i would do is sign-up EPC-You will need a credit card(it is free), windows machine that is fully updated. Using Internet explorer with JAVA fully updated.

EPC-net Online

A) Find VIN's for each year of the E350's(from 2003 to your year). Look on Craiglist or other vendors where they show the vin's

B) Put in the vin's into EPC, and look at the Transmission list of parts for each year; Watch the year the part revision until the revised part appears as the leading part, or the oil pump part number gets revised.

C) I'd call the dealer once you have the part number of the bearing to get visual ID..

I did this once to find a revised part. sounds like a pain, but it has worked for me. Maybe someone else can give you another approach..

Best of luck,

Martin
