ordered a wheel/hub bearing assembly. As I started assembly, I noticed the blue grease, and thought, great! I won't have to grease the bearings. As I looked closer, there was DIRTY, brown grease underneath the new. The bearing appeared to have been used, not even cleaned, and new grease thrown on to cover it. I ended up having to clean the filthy bearings, and regrease them before use. Was just going to let it go. But now, I wish I'd have taken a pic. not happy
