I have a 2005 Tundra (2 wheel drive) with 93000 miles. The truck has been very good mechanically since day 1. Over the past several weeks I have noticed I am getting a loud roar while driving. Road surface does not affect it and in the mean time I replace my tires and still the same sound. I can hear it developing at around 20mph and is very pronounced at 50mph and beyond. Today I jacked it and removed the 4 nuts and the back plate to check the bearings. They seem to have play and sounded a a little "course" as I was turning them. I suspect they need replacing. I called the dealer and they want 360.99 each side. Is this something I can do myself or do you need a press to accomplish this? I am pretty proficient working on the truck.
