My predator was making some horrific rear brake sounds. I stopped to take a look and found that my rear axle has a little bit of play. That, and I see new purple colored grease by the axle. The only thing I can think of is that my bearings are shot. I only have about 20 hrs on it so I think it was my fault. I changed to a 39 tooth sprocket and I think I may have over tighten the concentric locking bolts. I have the predator manual and in the chain tension section it says to torque to 45lbs. In the brake section of the book it says to torque the same bolts to 30lbs! Which is right? Am I right in assuming that my bearings are shot if I have play in my axle? Any help would be appreciated. Thanks.
