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...

Looks like you've got some machining to do.

Re: Dana 30 front wheel bearings
 

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.

Re: Dana 30 front wheel bearings
 

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.

Re: Dana 30 front wheel bearings
 

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.

Re: Dana 30 front wheel bearings
 

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

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

Re: Dana 30 front wheel bearings
 

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...

Re: Dana 30 front wheel bearings
 

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....

Re: Dana 30 front wheel bearings
 

TIME OUT!

Why don't you take the bearings that you have and simply match them up?

Clearly, the inner and outer bearings are different, the inner is larger.
The bearings you have have markings on them that can be used to buy more
bearing sets just like what you already have.

I strongly urge you to not modify the parts that you find because they are
engineered for a very important job. The changes you are considering can
make the bearings out-of-round -- which would be a disaster -- or at least
make them weaker -- which can't be a good thing on the front of your truck.

Re: Dana 30 front wheel bearings
 

TIME OUT!

Why don't you take the bearings that you have and simply match them up?

Clearly, the inner and outer bearings are different, the inner is larger.
The bearings you have have markings on them that can be used to buy more
bearing sets just like what you already have.

I strongly urge you to not modify the parts that you find because they are
engineered for a very important job. The changes you are considering can
make the bearings out-of-round -- which would be a disaster -- or at least
make them weaker -- which can't be a good thing on the front of your truck.

Re: Dana 30 front wheel bearings
 

I'm not gonna modify the bearings, Jeff, simply make bushings to press
into the front wheel hubs that are bored to press the bearing outer
races into. Bushings made out of 4130 would actually make the hubs
stronger, as the process of cold-drawing bar-stock produces steel that
is inherently stronger than any part produced by the process of
casting (like wheel hubs).

By boring the bushing ID to size and tapping the bearing race into it
before turning the bushing OD to size, the bearing race will keep the
bushing from springing out-of-round before I get it pressed into the
wheel hub. Bearing races are hardened to around 60 on the Rockwell
scale, and they will NOT deform. (Hit one with a hammer lol... it'll
shatter, but I promise it won't bend. Wear a face shield if you try
this).

I've been setting-up/programming CNC machining equipment to manufacture
parts for the automotive, aircraft, defense industries and every
industry you can think of for about 18 years. Latest project was
getting a couple of Giddings and Lewis Horizontal Machining Centers
(their HMC 170's) to machine Allison's new auto tranny cases for big
rigs (tractor/trailors, cement mixers, etc). Allison seems quite happy
with the cases they get from Walker Die Casting. And the HMC 170's are
quite impressive. The tool magazines hold 100 tools (face mills, end
mills, boring heads, drills, taps, reamers, etc.), they execute a tool
change in less than 2 seconds, they have a 3,000 IPM rapid-traverse
rate, they have 2 pallets that auto-change. Made a fixture on one that
holds the tranny vertically, bell-housing down, do all the radial work
on it. On the second pallet tranny mounts to the fixture via the (just
machined) mounting pads locating on 2 dowell holes we just put in, do
all the linear work on ths fixture (main-bearing bore, drive bearing
bore, clutch ring grooves, seal bores, etc.). Allison has a tight
tolerance from the centerline of the main bores to the pan mounting
surface, so this is where I have the machine facing the pan mounting
surface and drilling/tapping/reaming bunches of holes on the bottom.

I mounted a 2-foot-long wire brush off a floor-cleaner in a boring-bar
holder, machine swipes it over and inside the whole tranny-case last
thing, does a good job of de-burring the whole thing. Allison folks
were impressed lol.

Been doin this a long time...

Okay then, but why can't you read the numbers stamped on the bearings you
have, and buy more stuff with the same numbers?

Re: Dana 30 front wheel bearings
 

The numbers are barely legible, and I probably could if I could find a
parts supplier that had a master listing for whatever brand bearings
these are (only the SKU is stamped into the bearings, not the brand
name). O'course, if/when I ever sold this thing, were the new owner
ever to replace the front wheel bearings, they'd be going thru this
whole thing all over again.

i can understand why parts houses loose track of rarely used part
numbers on a 33 year-old jeep. Modifying the wheel hubs to accept the
bearings EVERYONE has listed is really not that big of a deal. I
simply thought somebody might be able to point me to the right bearings
and save me from sacrificing a lunch-hour working on a personal
project...
