What are the signs to know when you must replace a front wheel bearing on a 4x4?

 

It will squeak like your brakes, but won't stop/start when brakes are applied. Or just go with every two years a whole new hub/bearing assembly, especially if you are 4WD. Jack your truck up and push on your wheel, if it wobbles, you know you need a new assembly. Check the balljoints/U joints as well. If you are gonna change one side, change the other.
