xb33bsa said:if you are talking about the swingarm spindle,the only thing that connectcs the swingarm to the frame, (besides shocks)then the symptons you describe point to it being tight on one or both of the bushing sleaves

corrosion can cause this tightness ..soak it in pb blaster overnight ..then you can try whacking it out but you must use a precisely/propperly placed heavy backup\
look on a parts schematic to familiarize yourself and think to understand
