Altenator doesn't have to be removed. If I am correct this vehicle has a hydrolci tensioner with 19mm nut as part of assembly. Pull on it and this will relief the pressure and allow you to replace belt.

How do i replace the alternator on a 2000 tundra 4.7L 4x2 non serpentine configuration

I presume the serpentine belt is in the way. First, disconnect the battery terminal. Then make sure the serpentine belt diagram is readable and remove the serpentine belt. Then release the tension on the alternator belt and remove all the bolts and wiring.

The diagram should be on a ticker under the hood somewhere. No sure about the install but there is probably a tension roller that you just release with a socket to remove the belt.

Toyota Matrix 05/Auto.

What does the noise sound like? Does it increase w/ engine speed? It could be a bearing in the alternator, water pump, p.s. pump, belt tensioner pulley, etc. You can try to locate it by using a piece of wood (or long screwdriver) and VERY CAREFULLY touch it to the different components under the hood w/ car running, w/ your ear against the screwdriver handle, or piece of wood (VERY carefully due to many moving pulleys and belt(s) and hot components).
