hey everyone. i have an 06 brute force 650 sra. and when i ride it around i sometimes hear a clank noise from what seems to be the swing arm. sometimes its when i on the throttle or just rolling around and trying to hit bumps or jerk it to hear it....so i picked up a bearing kit off ebay, and when i was loosening the nut and bolt for the swing arm, they seemed to come off a little easy so i may just re torque it all and see what happens...but how do you know when you acually need bearings? do they leak any kind of fluid? if i try to shake the back of the quad real hard and look at the swingarm up by the brearings it seems to have a little bit of play. and when i do the same to my kfx 700 its solid as a rock...just need some opinions thanks.
