This is Chris's 8" front 3rd.....new US GEAR 529's
and also installing this donated Lockrite. 



I have new bearings going in also....so off with
the old ones using this little adapter my dad made
at the machine shop.
 


By having the center "point" at a location lower
than the grip jaws allows the puller to not want 
to bend and fall over.....the pull keeps the puller
straight up. The jaw fingers have been ground on
some to grip the bearing lip better. 


 
With the carrier bearings off, now it's time to 
remove the ring gear.....and throw away these locking
clips. I will use loctite instead. 


 
Punch the dowel out and remove the drive pin
and spider/side gears.
 


I partially assembled it and checked for less
than .015" clearance. 


 
With the locker in, it's time to file any irregularities
off the ring gear mounting surface.
 

 
New ring on....loctited and torqued to 70 ft/lb
and the new carrier bearings installed. 


 
US GEAR.
 

 
Gone as far as I can go with the case.....time
to work on the main chunk....even with the pinion
nut staked, the ole electric impact with a 30mm 
impact socket easily removed this.....in about 
2 seconds. Pink is the code for 4.10 gears?....
any "hidden meaning" there? 



My seal remover....big chisel and some side taps
from the hammer....
 

 
Part number for the pre-86 main rear pinion
bearing......32307JN by Nachi. 


 
Small front pinion bearing number 30306Ja by KOYO. 


 
Carrier bearing race 17831 roller 17887 by NSK.
 


I chose a .099" pinion shim and pressed on the new
bearing....that's the Toyota factory solid collar
and I chose .052" worth of shims for a first try.... 


 
With just the pinion installed and carefully 
ramming the yoke down.....I found a nice 10 
in/lb of pinion pre-load. So that means no 
repetitive dis-assembly needed to get the pre-load
right on. Now I can place the carrier in and
finally get it ready for the 1st painted pattern check. 



I set the backlash in the ballpark but made sure
I had some carrier bearing pre-load.....roughly
about 40 ft/lb on the bearing adjusters. That way,
when I wedge a crowbar between the ring and carrier,
I won't get any ring gear deflection to screw up
the painted pattern.
 


A very nice pattern on the drive side..... 


 
Coast side mimics the same. At this point, I tweaked
the BL in at .007" and used some arm to get good
 carrier bearing pre-load. 


 
Just for the fun of it, I checked the pinion
pre-load with the added resistance of the 
tightened up carrier in place.....adds about
10 more inch/pounds to it.
 

 
Then I pounded the new seal in.....I used an old 
race that fits over the top nicely here. 


 
Plenty of grease on the rubber seal and blue loctite
on the threads......then placed the yoke, washer and 
new nut on.....held the gun on it for about 5 
seconds(200 ft/lbs).... 


 
Just for the fun again, I checked the torqued 
required to turn the pinion with everything in
place......even with the grease on the seal another
10 in/lb was felt due to "seal" resistance for a 
total of 30 in/lb accumulative.
 

 
swish swish SWISH!
