Yea, good practice. It's odd these are the same style bearings and construction I remember from the front wheels on old rear wheel dive cars I owned and rear wheels on front wheel drive cars. I have serviced bearings like this many times albeit 25 years ago.They didn't call to be repacked every year. Seems excessive and after my first inspection today I wonder just what might go bad if they are well greased and adjusted. After 12000 miles (plus the milage getting it from Indiana to CA originally) the first one looks great, like new. I think I will go ahead and repack and inspect them all just to make sure they look like the first and plan every 2 years at which point I will just go ahead and replace everything. At one year I will use the ezlube. For us that will be about 12-15,00 miles every 2 years.
With modern trucks exhaust brakes the trailer breaks just don't get used that much, Same on the truck. Before we traded it in our truck had 55,000 miles and the dealer measure the pads and said we had 70% left. Plus I drive like a little old lady. :halo:
