Be aware that the "Nissan" FW105 "0823" bearing is more difficult to locate, or maybe a better way to say it is every parts shop caries the FW176 "08A01" "Subaru" bearing and will try to convince you they are the same.
If it does not have the NTN 4T-CR1-0823 part number or the SKF FW105 part number on the box or better yet on the lip of the bearing itself, it is probably the "Subaru" bearing.
Heck, have them pull a FW176 too and make sure they are different. Apparently, even some boxes saying FW105 have the Fw176 parts in them.
