bones Swiss are the best bearings.they are on the expensive side but are worth it.
in the wheels
When you take the old bearings out they should have a number on them, write that number down and take it to a skate shop, or store that sells bearings. or just take your trucks or the whole board to a skate shop they will help you out.
