Whirlpool washer not spinning. Model#LSR7233EQO?

I just replaced the outer plastic tub because it had a hole and was leaking. I put it all back together and everythng works fine until the spin cycle and now the spin cycle does not work. Could I have gotten something back on too tight that prevent the inner tub from spinning or did I do smething else wrong? I have worked so hard to fix this thing, I would really appreciate help to get this finished right.
