swingarm problem?

[ryan711]

I have been feeling this kinda loose feeling from the back when I get on the throttle. So I leaned the bike over on the kickstand and tried pulling my swing arm up and down and left and right and there is about a 1/4 in of play up and down. Now I dont know if this has always been this way or just noticing the play. What could it be? I dont have any grinding sound like a wore out bearing and it has no slack from left to right. Any sugguestions? Maybe just tighten it up?

Thanks sheeple

Bearings inside the swingarm may be bad. I had this same problem and just fixed it today. I had some real akward grind/squeak revolutionary type noise in the rear end and also had that 1/4" play. I was suggested Swingarm bearings.. Got the bike apart and tried tightening the pivot bolt to make sure it wasn't loose and it still had play... So I took the spare Swingarm I had and put it on, no play. No play whatsoever now. Hope it fixes the multiple issues it was causing.

Hope this helps. I have an 03/04 636

There are also needle bearings inside the "dog bone" holes in the SA. Also the holes in the aluminum "dog bone" can get all hollow out...also check to make sure the spring isn't loose when you have 0 pressure on the suspension (not hanging weight or actual bike weight). Clapped out bikes develop slack in the rear suspension that is noticed most at BP.
