E-Net Diag = Wheel bearing?? *Long but Cliff notes

[MrFairlady]

"the Skinny":
Ok..I've got a 91 DOHC hatch (stock motor,etc) w/ approx 180k miles on her (been bone stock her whole life untill Coilovers a few days ago)..and she is ULTRA,ultra clean...Been driving it for about 8+mths as my daily.It had to have been a Ex-Grandma's car its in that Great of shape...just a good amount of mileage...sort of.

1st noise:
Now I've been hearing a noise from the Right rear wheel area (or seemed to be between the Wheel and the door area I thought) and its a low pitched Creaking noise but only happens interm....seemed to only do it on Chassis flex like speed bumps,driveways what have you& .I thought it was the Worn out shocks...but I just put coilovers on it and its still there.

2nd noise:
It also seems to make a swirling noise while rolling 30-40mph tops ,in gear and more/louder when letting off the gas then On the gas.Slight Scraping noise Slows as my car slows but the min I throw it in Neutral while rolling.....it stops.

had a tech/friend @ the Lexus Dealer i work @ and he thought it was more Trans/driveshaft related after hooking up the Stethascope (spell) whiel on the lift,in gear,tires spinning.

MAIN QUESTION:
WOULD a Wheel bearing make a Creaking noise w/ body Flex like described is my Main question...I know it def makes sence when wheels spinning - sound getting slower as car gets slower deal...but never had a Wheel bearing issue in all the cars I've owned.

thanks
