Ive recently dived into replacing my rear bushings.  Ive noticed that the bottom A-ARM floats freely when disconnected from the shock but the upper A-ARM (no grease fitting) is very sticky and seems dry....its tough to move and stays in place when I let go of it....should the upper rear a-arm float freely or be sticky in its movement?  should I disassemble it and grease it up?

thanks,

Depends on what type of bushing it has. If it doesn't have a grease fitting I suspect is had a rubber bushing and it only flexes on the inner sleeve. You can look up the bushing on Alpha-Sports and see.  If so, it will be some type of unit like this one they now use in Kawasaki. If not, then there is a problem...lol

stock bushings tend to get "stuck" on my machine i take it aparte and apply some grease. Don't over torque the bushing if you do they will tend to get stuck.

You have same bushings in upper and lower a arm
