I have an eight year old Frigidaire washer/dryer combo. ~6 months ago I experienced leaking coming from directly underneath the tub and replaced the tub seal. This resolved the problem for a period of time.

However, recently the leaking has re-appeared from directly underneath the tub (along the driveshaft). The leaking only occurs during the agitate phase and does not occur during the fill, rinse or spin phases.

Any suggestions on how to further diagnose? Thanks in advance for suggestions and help.
