i am getting ready to install my doubler, so i put the 203 & the doubler together. once the 203, & doubler was bolted up tight it was/is very hard to turn by hand when it is in low range only. it feels like the gear i removed from the part of the 203 i chunked is binding on the gear it meshes with in the range box part. the gears don't have any burs either. basically i am asking if this is normal (which i don't think it is) & if not what should i do? also i didn't notice it before i took the 203 apart. thanks for your help in advance.
