Thanks again guys,
Yes, the five nuts on the "cover" plate are all off and I pried the plate loose. Of course I can't remove it completely cuz it's stuck behind the axle flange.
I went back to scrutinize the Driver's side that came off so easy. I couldn't learn anything that tells what's wrong on the Pass side.
I wouldn't be surprised if someone used JB weld on the $&$#^* outer bearing race on the Pass side. It bears evidence of being jury rigged, with the red silicone goop and harsh tool marks on the Driver's side "cover" plate, which is even warped enough it has to be hammered over the 5 studs to sit properly....

So there's all that.. and what it implies about the low level of care given by the prior "mechanic"...

I can't share photos at the moment, I'll try later tonight..
Best,
