very easy to remove the powersteering, the fluid in and return are right next to each other so all you have to do it loop them. but if you do remove then leave some fluid in there, helps for lubrication. i am used to no powersteering so dont find it that heavy, but others dont like it. parking is when its heaviest and driving corning hard it gets heavy, but this gives you better feel. your problem sounds like a loose belt, screeching is normally a sign of it loose.
