did you make sure all the bolts were out?

[M4wdFab]

i am 82.75% sure all the bolts were out.

[Ryan]

Did you heat it up?

[mr.mindless]

Had propane only on it for at least an hour

[Ryan]

Wow, thats crazy.

[mr.mindless]

there's one in stock at nuway, hoping I can grab that one today and meet Vic tomorrow with it, then grab the other that's coming from Buffalo whenever.

The only potential challenge is spline depth. My CVs have a seal surface on the inboard shoulder so the splines end early.  The late unit bearings are full splined and it bottoms out about 1/4" too early.  I'll see what the early bearings do, may have to knock some splines down.  Hoping I can keep the bearings off-the-shelf though in case I need to replace one but I can't imagine one will go bad when they last 200k on Jeeps.

another couple potential issues - the old style hub has a lot more stick through, not sure if it may give CV alignment/plunge issues.

Looking at the knuckle, I may want to add some gussets if I'm taking that large bore size all the way through.

Really too bad that hub wouldn't just fucking press apart. what a pain in the dick.

Vic says he gets to the shop between 8-8:30, I'll aim to make my plan tonight and meet him there, then.
Maybe I'll try pressing the hub apart once more but I really am thinking it'll snap.

Here's the OE Eagle hub:
Flange diameter measures 5.70", hub pilot diameter measures about 3 5/8" and the knuckle steps down beyond that diameter to hold the inner seal.  I'll get it bored out to 3.75" through.



Here's the 90-99 application Jeep unit bearing, TIMKEN Part # 513084:
Bolt Quantity=5 Flange Dia=6.043" Bolt Circle Dia=4.5" Bolt Size=1/220" Wheel Pilot Dia=2.812" Brake Pilot Dia=2.832" Flange Offset=2.133" Hub Pilot Dia=3.942" Splines=27



And here is the 84-89 application unit bearing, BCA/ Timken 513107

Hub Assembly; Front Wheel Bolt Quantity=5 Flange Dia=5.69" Bolt Circle Dia=4.5" Bolt Size=1/220 Wheel Pilot Dia=2.81" Brake Pilot Dia=2.83" Flange Offset=1.81" Hub Pilot Dia=3.75" Splines=27




The old style is much deeper, need to see how this will effect CV shaft depth and alignment, I may have to go for the newer style after all and figure out what to do for brake rotors 
I've got a couple things to check before I pull the trigger on milling, I think.  Still hoping to do it first thing tomorrow though.

Looking at the knuckle, I think I'll want to gusset the top where it necks down, going all the way through with that diameter will take away a lot of the material that holds the top to the body. The caliper bracket bridges the back side but I think I'd want to add some material back in for long term durability.

You cant just buy new hubs that fit?

Sounds like it would be easier to swap in a D30. 

[mr.mindless]

Nope, can't.  would be like buying a loaded spindle for a 60, doesn't exist. it's "serviceable" (until it doesn't come apart)

[Nick]

can you do the socket trick in the u joint to pop the bearing out?

[mr.mindless]

There was no issue whatsoever getting the hub out of the knuckle.  That took about 2 minutes, tops. It's pressing the hub apart to change the bearings.

[Nick]

man way to not explain every thing clear!!! gawddddddd

[etk300ex]

What a pile

[mr.mindless]

You're just jealous, hater.

84-89 unit bearings will work perfect. Reinforcing knuckles for AM boring now!
