Hi everyone,

I just replaced both my front wheel hub assemblies in my 2003silverado and about two days ago the passenger side moans and howls again when the engine is about 2000-2600 rpm. The shocks and struts are probably old as well, but my freind said it could be an internal part of my engine like the lifters but the engine doesn't knock and tick or anything. The wheel hubs I used to replace were NAPA so should I go get a replacement while I'm under warranty or is it maybe another part?

 

Oh and this only happens while driving not when the truck is idling so that why I don't think it's the engine causing this noise

 

rpm wouldnt have any effect on wheel bearings it would be the speed and load changes that did. If you can make the sound sitting still but at 2000rpm i would start by removing the belt and sseeing if the noise is still there. I'm leaning towards a pulley issue by the sounds of it
