I think I need to change the front wheel bearing on my daughters 2003 Corolla because it is making a very noticable roar that varies in pitch and volume as the speed changes. It has new correct size tires, no fluid drips anywhere, good brakes, it just makes this noise that has me worried. The latest Haynes book says that the bearings are a press fit in the hub and that the replacement should be done by a "professional". Thats nice but I can't afford a "professional" when I can do the job myself as I have done on all the Toyotas, Mazdas, Chevys, and Fords that I've owned in the past 40 years. I was quite suprised when the Toyota parts guy told me the factory service manuals (2) cost $175.00, hence the Haynes book. So, my question is " Does anyone have the proper procedure in detail for replacing the front wheel bearings on a 2003 Corolla, for the layman. What I am most interested in knowing is what stupid thing NOT to do. Any help would be apprectiated.
