sqweeking noise n/s/r wheel
 

Hi after some help with a noise that I can't pin Point.it's a 55 plate wrx only does it when driving for more than 15 20 mins then it sqweeks really load with bumps in road I could hear slight knocking on shock so removed and 're packed with grease still there.
Reduced sqweeking when on throttle but when on over run ie off throttle sqweekss like mad every one that listens to it says it's coming from wheel. Any ideas also have a slight grumbling wheel bearing that side but carnt pin to front or back I suspect front don't know if it's related..
