The spider is not going to come off ... at least not under my effort. Don't know if the anchor screws are sealed with something, tried one (T35) and slightly damaged it so that's the end of that. Gave it an initial spray-down and the most A-L-A-R-M-I-N-G mass of lint and smutz flushed from behind. Will apply a pressure washer tomorrow. I'm halfway considering replacing the basket/spider, just for reason of doing the job better and longer-lasting (assuming the bearing deal is successful) but that would up the cost by more than double.
Got the seal and two bearings out and rear tub cleaned.
