Well I broke down and finally replaced the front sealed bearing and seals. While I was at it I changed the rear tires as they were 8 years old. For those of you that don't know it, after a tire reaches a certain age, shops are not allow to repair any flat for you. I believe that the age is 5 for trailers and 6 for cars.
As for the bearing change, don't believe all the horror stories about all the special tools or equipment you need. I did it all in my garage with regular tools and a little "Redneck" ingenuity and yes I had to look up that word !! Sure rides quieter too. Checked all the break pads(front & rear) and they are all fine. Cost was $400 for the tires from Sears, mounting, balance and free repairs or balance down the road and $360 for the 4 sealed bearings and 4 grease seals. The sealed bearings did not show any visual wear but the 2 outer ones felt and sounded dry.
