Dana 30 front wheel bearings

'73 CJ-5, Dana 30 front-end... got the wheel bearings from AutoZone (2
per wheel, an inner and an outer). They have them listed as the same,
but the race for the outer is sloppy in the hub. The hub obviously
hasn't been "wallered out" (as these local Tennesseans would say) but
there's at least 3/32" of cleareance in what should be a pres-fit.
Anyone know the right outer-bearing, or do I need to just make a
press-fit bushing and bore it to press-fit the race into? (been maching
to within a few tenth's tolerance for many years)

Thanks in advance for your help...

They look the same:

Looks like you've got some machining to do.

They sure are different bearings in my CJ7's D30! They look close,
but....

I just replaced my inner and got a bearing at NAPA. The box says BR50
with these numbers: LM102949 and LM102910. One number would be the cage
and the other the race.

Hi Mike,
I know they are different on the Dana 44s, they look similar, but
have a different cone angle, and fortunately for me the outer will not
slide all the way on the spindle.

The spindle is bigger for the inside one too, I just looked at a spare
spindle. The inner bearing slips on easy up to the end, then it press
fits the last 3/4" on the spindle.

On my '81 CJ5, the wheel bearings are different.

I had a spare set to read the numbers from, but I musta installed them ...

I appreciate everyone's input. Think I'm gonna make a bushing at work
tomorrow night. I've been researching this all weekend, everything I
find lists the inner and outer bearings as the same. Gonna bore a
piece of pre-heat-treated 4130, tap the race into it, then turn the OD
about .002" over the hub bore before cutting it off and pressing it
into the hub. That should keep this thin-walled SOB from springing
out-of-round.

Happy fourth, everyone. Y'all be safe...

How are you going to make the bearing fit over the spindle? It won't in
my Dana 30.

I gave you the correct part numbers for the bearing and race....

**** I didn't even think about the inner race ID or spindle OD... I'll
run those numbers thru the guys at NAPA.. Thanks, Mike,,,

we ALL experience brain-farts sometimes...
