New front bearings and CV Axle. (some observations and questions)

I recently had an issue with a clicking/bumpy-ish vibration on my car. (almost like a baseball card in the spokes of a bike) I could feel it in my car going 60-75mph mostly, or making a turn at a slightly higher than normal speed. I bought new front bearings & CV axle. (TRQ BRAND on AMAZON) The bumpy/click is gone but I've noticed two new issues.

- The car now makes a slight "howl" sound between 65 and 73mph. (car is smooth and quiet otherwise)
- If I brake going slow there is the sound of a slight knock like something is shifting a tiny bit with the momentum of the car. Then when I accelerate it knocks again a bit.

My. mileage went down to 38 from my normal 41 but that could just be driving in the wind... sample size not large enough.

125k Miles on a Gen 2.
Other recent care: New Spark Plugs 1k miles ago, new front struts and control arms.
