So my bikes rear end started to feel very stiff so i decided it was time to re-lube all the bearings in the swingarm and rear suspension link. I got the link out and found my problem. All bearings were completely frozen with rust. I am obviously replacing them. The swingarm is still attached to the rest of the bike because i cannot (yet) get the bolt out of where it goes through the frame. But moving the swingarm by hand yields very smooth movement and no noise whatsoever, so it makes me thing those bearings might still be in good shape. I guess what im asking is can i get away with just replacing the rear link bearing assemblies and leave the swingarm the way it is, or should i just replace them all while im at it. Cost is a factor for me here also.
