OK, I found the howling noise I originally thought was tire noise. It turns out to be the driver side wheel bearing. I'm looking for a tutorial on replacement (basically removal and replace) since I'll have someone else press the bearings on and off. Can't really find a very precise answer to removal. Is there a step by step on here? Do I have to remove the ball joints, etc? Thanks in advance. Also do I need to use oem parts?
