"Help

Well i finally have money to spend on my car, and i was planing on changing the rear wheel bearing.and the u joints. The problem is that i don't want to pay some one to do something that i might be able to do these things with the right instructions. So the question is how hard would it be to change the wheel bearings. Where would i come upon instructions to change them?Oh my Car has an 7 1/4 in it.

Thanks
