Can anyone help me before I turn my washer into a smoker

!!! I have a frigidaire stackable dryer/washer, back in March I replaced a seal set which seemed to have fixed the leak but now the thing is leaking again. I rechecked the seals and there is not a problem with them am I missing another seal that might be bad? I do notice when it spins that it is making a high pitch squeal. Someone...anyone help....
Thanks Joe
