I need to replace or tighten my wheel bearings on my 85 chevy 3/4 ton 4x4. It has automatic hubs. I can move the tire side to side and when it sits, the passenger tire leans in. Is this just the wheel bearing needing to be tightened? I know there is a clip inside. Is there a tool that I need to fix the hubs? What should I look out for when doing this? I'm hoping I just have to tighten the nut and that will fix it.
