Re: Bearing Buddies
I'd say that if the bearing set is making noise, both bearings need to be thoroughly inspected. I wouldn't stop at just the outer bearing if it's found to be bad. Best case it costs you a seal, worst case it costs a bearing and a seal, but you definely know what you have. I've serviced bearing sets that the outer set was great and the inners were the problem. I've serviced wheel bearings for over 30 years and have seen all kinds of failures.<br /><br />You don't have to have "foreign debris" to have a bad bearing. All it takes is one bad pit in either a race or a roller to make the noise and start the deterioration process.<br /><br />I'm not trying to argue with anyone, it's just that there may be people out there that want to learn how to do it right. Servicing on a regular basis is great, however, that doesn't mean that the bearings are guaranteed to go from service interval to service interval. So from time to time, you jack it up, check the play and listen to what the bearings are trying to tell you, regardless of the service interval. Very cheap assurance.
