Noisey sound getting louder during spin cycle

Please note that I went online first to get an idea of what was involved.
I removed the back panel using a cordless drill w/attachment for the screws. Then the top. The directions that I received online was very helpful, but I didn't remove the whole tub assembly. I don't recommend doing it my way, but it can be done without removing the front or the whole tub assembly. After the motor and the big pulley was removed, I removed the bottom "shocks". I then took out every one of the cap screws that hold the 2 halves together. When that was done the two halves were loose. I then supported the bottom and took out the two springs. The back half came out quite easily then. It is then necessary to use a mallet to remove the inner drum from the bearing and back half of the tub. I cleaned and inspected the "spider" which was fine except it had old soap in it. Then using a dremel tool with a plastic brush I cleaned/polished the shaft of the inner tub. The new rear shell fit perfectly. Supporting the bottom of the front half of the tub, I then placed the back half assembly (with the pulley replaced on the shaft) in proximity and started the cap screws. It is weird how the 2 halves don't want to stay in correct alignment, but it can be done. After I got most of the top screws in, I used a ratchet wrench to tighten them to almost where the 2 halves were touching. That helped with the alignment process. When all (Ibelieve there are around 17 screws) were started and the 2 halves were aligned, I then started at the top and tightened to a loose fit. The second time around I tightened to semi tight. At this time I could put the springs back on (greatly improves ability to reach the bottom screws). The third time around I put them all tight. Every thing went back on without a problem. I attached water and power to the unit and ran a cycle with the top off and checked for leaks. That's it.
