Thread: Roller fairlead not spinning?

Have you tried to pull it apart? If not, do so and try and clean it. You may find it has el-cheap-o bearings in it, which when you've got it all cleaned up, maybe put some good quality ones in place.
Being generally the first thing to hit the mud, I wouldn't think it would take much to clog them up anyway. So periodical cleaning and a grease, would be a good thing.
Probably not really of concern right now, but the damage to the rollers at present whilst your running steel should be ok, but you'd want to clean them up a bit if you change to rope.
