Rebuilt two of my DD's at the same time, one with a 6203 the other with a 5203. The 5203 is still whining sort of loud, the one with the 6203 is relatively quiet. Is this normal or should I disassemble and replace the 5203 with the stock size skf. About 30miles since replacement of bearings and seals. the one with stock bearing is a 09 the one with 5203 is a '10.
