Inside your differential you have bearings or gears or both. When it starts to make noise then it most likely means that they are worn out and are due for replacement. Preventative maintenance with regular fluid services can extend the life of your differential by many years. They typically need be to be serviced every 30K - 50K miles so depending on how much you drive every couple of years or so. If you think it's been a while since you had yours serviced or you would like us to find out if it needs to be done give us a call and make an appointment with Olivia.  (541) 791-2886
