The bearing set sold at Autozone and NAPA have a sealed bearing. My 9" has
the separate bearing and race. It came stock this way and when I replaced
the axles a year-and-half ago they were the same separate bearing and race
assembly, which I cannot seem to find.
Is there a trick to installing the sealed bearing set? I can't imagine having to
beat the axle into place to seat the bearing, and nut-tightening with the flange
seems hardly a durable setup. any tips would be appreciated!
Call the other-auto-parts stores and ask for a "set 20" tapered bearing set?
My notes say the seal number's 3195 but I believe it's included in the box
with the "set 20".
'75 F100 parts truck came with one side original "set 20" tapered bearing
(gear oil) and other side had the one-piece-sealed-bearing (grease packed)
with the separate seal behind it.
BKW sez they are interchangeable. (?)
The sealed ball bearing came out with the axle (outer race and all) and left
the seal inside the housing. You can change that-seal without a press.
The older "set 20" tapered bearing leaves the outer race in the housing but
the seal is trapped under the retaining collar and bearing so the bearing gets
gear oil. At least that's how I 'member it. ;)
Pressing a new-axle-retainer on the new axles was an eye opener for me.
My 8 ton bottle jack couldn't do it, had to use the 20 ton.
I'm going to get help with that-part next time. ;)
I can drive and hour to Willcox and -save- time. ;)
