Wow. Was anybody else confused by the above replies?
I just pulled the hubs from a customer's M715 and here are the orig part #'s. The bearings AND seals were the same for front and rear, contrary to the parts manual and to some of the above posts.
Inner wheel bearing:
387A Cone/Roller (Timken)
382A Cup (Timken)
Outer wheel bearing:
18790 Cone/Roller (Timken)
18720 Cup (Timken)
Wheel seal:
475384X54 (National)
A set of bearings and seals should run around $60 per wheel. Don't buy them at your local parts store. They'll charge you at least twice the going rate. Find a bearing distributor or order from an online warehouse.
