meet the new gears / mini locker rev1

Ok- so the jeep is now a jeep-chevy-scout-isuzu hybrid.  It IS all American though- the isuzu came with a rear dana 44  (courtesy of the USA)  with 4.30 gears. (with a custom center pumpkin)
The differnce is that the isuzus ring gear is thicker and the pinion gear , the gear side bearing is puny compared to the scouts the yolk side is exactly the same.

*****update...  isuzu had proprietary dana 44s with special carriers and pumpkins-  they won't work in US vehicle dana 44s- they are >1/2" off!!!!******** regardless of what the guy that sold them on ebay says.
It falls half way through the scouts race before seating.  the isuzus bearing race wallers around in the scouts housing.

The first time since 1974 that these two guys have parted ways

Note the scouts ring on the left, and the isuzus on the right. 
 The  inner spacing ring measured exactly the same between the two, it just that one on the right is thicker.
Because of this, if the carrier pin ever has to come out, the ring has to come off.

Here's the pinion and all accessories from the rear axle.
The shims go between the housing and the bearing races.
Note the mangled oil slinger next to the gear.  somehow
parts of it are chewed off.  It turns out the rear had koyo
bearings but still had timken carrier
bearings, so it had been gotten into before.

 a mini spool isn't just a name- it really is small
Here's what it looks like taken apart. The round parts go into the side of the carrier, and the carriers cross pin goes through the square blocks.  100% lockup.  If I want to change it back later- the spider
gears can be back in within an hour.
