Sears DieHard Platinums arre relabeled Odyssey batteries. They've been working well in my Dodge dually and race car! They are less expensive than the Odysseys.

As for wheel bearings, the only solution is trying to find a better wheel bearing grease. Years ago I found an obvious difference on my heavy trailer when I switched from conventional HD grease to Amsoil's Racing Grease: http://www.amsoil.com/shop/by-product/grease/dominator-synthetic-racing-grease/?code=GRGCR-EA
