i hear creaking on the passager rear end of my truck

What is your question?

when I drive over 10miles it starts and over 40 miles it goes away... it doesn't come back until i stop the truck and it sits for over 20 minute or more. Then if i start and go somewhere it's back until i go over 40 miles or faster. Is that Suspension issues or Hub Bearing? If I make a right turn it will go away

How long has your 2012 GMC Terrain had this problem?

a few weeks
