I just inspected my brakes and rotated the tires. The original brakes look like they will last to 200,000 miles on the front, thanks to the liberal use of my Jacobs exhaust brake. The rears should probably go 300,000. The exhaust brake has never given any trouble at all. There are no signs of corrosion under the truck or in the brakes. I am on my second set of tires and they are wearing perfectly even. Got 87,000+ on the originals. I always keep the tires at 60 psi minimum and higher when loaded. There is no wear apparent in the ball joints or tie rods or steering box. The truck has never seen an alignment rack! It also has never seen snow or ice, so no salt or calcium chloride either. The only thing I did find was an indication the left rear axle seal is just beginning to seep. I will replace that shortly. All in all, this is the best vehicle I have ever owned. Or even heard of for that matter. One lift pump, one fuse and one bulb are the only repairs!
