OK, I've got my rear wheel off to get the rotor turned and brake pads replaced. I'm planning on replacing the 6304 bearing , but I noticed that there's another bearing also. In the service manual, it's number is NK 26 x 35 x 25/3A. Is it neccessary for me to replace this one as well? My bike is an '84 VR with 71,000 miles.
Thanks!
