I'm really confused, the front d. shaft is loose, they say both LT230 and front diff need a rebuild. I am in the West of Russia and could easy get "new" t-case n' diff from a junk yard in Russia, Lithania, or Poland. But I don't want to go that route. It seems there is lots of things out there, so I got overwhelmed and confused. Diff ratios 4.1 vs. 4.75, KAM vs. Leyland, ARB, air locks, electric locks, self-locking, rebuild kits from this company or that company, and so on. One fellow I know fitted a P38 rear diff to his RRC and he swears this is the way to go. Is there a common knowledge what to do best? Labor is pretty cheap here and I can do some things on my own, too. The poit is, if I am to spend time and money on this old rust bucket, I want to make upgrades rather than just fix it so it'll run for a while more. Thank you all.
