Vibration at 75mph. Bad hub?

67Dart273 said

I HAVE had a failed hub, years ago, on my 70 RR. The inner race on one side "ate" the bore out so that the race was !!!LOOSE!!! at the bottom of the hub bore.

I could not tell by wiggling the hub around on the spindle. It sure as heck caused a "wierd" vibration.

Ditto. In my 69 Dart slant w/ 9" drums, both hubs failed like that. The outer race spun in the hub, which ruined the hub.

The first time it happened on a trip from GA to CA in 1986. Because of a squeak on turns I stopped and had a shop in AL change the front wheel bearings. I watched, and it appeared he did it right and backed off a little on the spindle nut. The bearing failed in MS and welded the bearing race to the spindle, which a great welder cut off w/ Ox. The outer race spun in the hub, but they had a Valiant for parts w/ 9" hub in the yard.

The other hub failed in 1989 on a trip. I took it to Brake-O and they put a new drum on the bad hub, charged me $350, then showed me the wobbly race and said "you can fix that yourself". I learned to avoid shops. No 9" hub at any junkyard in Atlanta, so drove the car back to TN and found a 9" hub there.

If your hub is bad, you might consider changing to 10" drums, since I suspect 9" hubs are marginal. You can get almost free since many change to disk brakes (another idea, many posts). Indeed, my new 64 Valiant has 9" drums so I'll start looking for spare hubs now.
