An update for those interested:

All was going great with the ol' Savage 25 until a few tanks after the three
gallon mark.  It started when the right-rear carrier bearing blew it's guts
out at 40mph, completely lunching the rear differential in the process.
Destroyed ring, pinion and case halves.

Rebuilt rear diff with new R&P, new cup, new bearings and new case halves.
Spiders were fine so I left em' be.  Rebuilt front diff with new cup and
bearings.  Replaced tranny and differential outdrives with HPI heavy duty
parts as well as front and rear center shafts with HD parts as they were
pretty beat up.  Rebuilt my steering servo as well.

Fired her up after repairs and two tanks later clipped a tree at WOT (was
weaving thru the line of trees along my property line and got a little too
brave).  Left-front, lower a-arm and dogbone go flying in opposite
directions and Sav lands about 20 feet down from the tree.  A-arm was
obliterated, but I managed to find both it and the dogbone.  Lots of CA and
20 minutes later I went to fire her up.  One-way bearing starts slipping.
Arrgh!  Managed to get her to start and lasts 5 minutes before a-arm lets go
and I'm right back where I started from.

Pout.

Drink beer.

Go to garage with laptop and order Golden Horizons silver aluminum lower
a-arms and new one-way bearing.  Yank the motor and remove rotostart to get
at one-way.  Backplate chips off where the screw for the backplate threads
in (corner fell off).

Curse.

Drink more beer.

Blasted one-way clean of oil and reassembled, using some HPI threadlock on
the busted corner to hold her together.  Finally managed to pop the carb off
and sealed all contact points with silicone.  Reasembled motor and fired
right back up.  Ran a 1/4 tank thru at idle to let RTV cure and went to bed.

She should be good to go as soon as I get my parts.
