While the original NTN bearing in my 1991 Acura Legend was made in Japan, this one is made in Taiwan. This may be the reason for the specification mismatch for the same part number. Although the P/N is listed as 6203LLU it will show up as 6203LY on receipt which is normal as the same 6203LU is listed on OE stock. BUT when you check the ID, they don't match. You need 17mm instead of 15.875mm ID
