Hub oil seals and bearings

Post by refit1701 »

On Garbee's parts interchange list, it shows three seals; inner oil seal, inner axle seal and outer flanged seal. I only see the two, inner oil and outer flanged on mine. There's the "paper" seal on the axle but I'll use a tube of permatex for that.

Is my hub missing a seal or is that one for something else.

The outer bearing looked ok, but the inner bearing race has several slot like depressions running across it. Should I go ahead and replace both sets (outer and inner)? Seems like that's what I used to do on Mustangs.

Wait till you see how much the bearings and races are. I would call AB Linn or Sid beck for the parts as they were MUCH cheaper than Napa.

I would recommend it if you can afford the parts. My experience has always been that if one bearing is shot, the other isn't far behind it. Better to do the whole job once than to do half the job and then wonder how long it will be before you have to do the other half.

Dang, you guys got me shell shocked over the bearing prices and I haven't even called anyone yet!!

**Edit: The inner bearing is way cheaper than the outer, which makes no sense since the inner bearing is larger. Maybe the outer one is not as popular.

My bearings have Timken on them currently, so I guess someone replaced them in the past. As I said before, the inner seal is all beat up from being reused, I think.

A local bearing supply house will be your cheaper source most likely. NAPA is pricey on bearings in general. NTN or KOYO are 2 high quality product lines & are much cheaper than Timken. You can check the military sources, however with UPS cost considered, your local bearing supplier may still be the cheaper way out simply because there is no shipping cost involved.
