Ok i need to replace my rear axle bearings and seals on my 2006 ford f150, there was some evidence of fluid on the back side of the wheel and its making a grinding noise. I called the dealership and of course they wanted about 500.00 smackers to do it. I know its fairly simple but does any one have step by step guidance. I have my calipers and rotor off, but thats as far as i've got.
