I think it's pretty unlikely. It's a new power steering pump. But the weird thing is is last night I was driving on a pile of logs to show my grandpa the grinding sound.. And I couldn't get it to do it. It was probably just because he was there but still. I took the axle completely apart and put it back together. And never saw anything. Im going to see if it will make the noise today...

 

So I just tried a hill climb at a gravel pit that has made the noise before. I put it in 4low 1st gear and gave it hell. And no noises at all. So i either fixed it by taking the axle apart and putting it back together, or its temperature related..
