Some of you may know that four years ago I had a wheel bearing failure on the highway which resulted in a front wheel nearly coming off at speed. I took that incident as a sign that I need to be better about maintenance tasks on my bronco because quite literally, that could have killed me. I replaced the spindles, hubs, bearings, and brakes at that time (GM disc brake conversion on a 72 bronco dana 44 front end).
I decided last night that I needed to pull the front hubs and inspect the bearings, if for no other reason than to quiet my mind. The bearings are still packed with grease and look good, however I found some witness marks on the spindle which lead me to believe that all's not well. While I know that the bearings basically slide onto the spindles with a tight fit, I don't think the bearing is supposed to spin as it appears to have been doing here.
Having slept on this last night and looking at this photo with fresh eyes, it may be that there's just grease and grime "stuck" in the machining marks on the spindle. As you can see there are machining marks along the whole length of the spindle, so perhaps this is a false flag and I am overthinking things as usual. It doesn't look like there's been any heat or other damage. Later today when I get done with work, I will probably hit it with some spray cleaner to see if my suspicions are correct.
In the mean time, What say the experts?
