What was the part number for the correct part? 1.75in bearing??i had to go to the dealer for mine. i'm 2wd longbed and all the local auto parts store all came up with the same part # which the ID was too small. when i went to the dealer they ordered what they thought was the correct bearing but when it showed up it also had the smaller ID. So they ordered the optional bearing which was in fact the correct one when it arrived. go figure!
