May be the installation does not meet the good, or spindle hole or bearing into something, spindle bearings generally Angular contact bearings, installation should pay attention to the direction and pairing You only have new clothes too, before installation using gasoline or diesel cleaning spindle hole and bearing, and then to the bearing Dayou, high temperature grease, pay attention not to exceed the bearing gap of one-third of a, then is assembled out, this is very important, in order to, pay attention gap, direction, parallel, and even cleaning. Should go bearings fixed on the spindle and bearing bore inside, so rigid. I do not know you're using what bearing, I changed a lot of times, this is my experience.
