Just finishing up my LT230 swap into a '94 RRC LWB. Guessing I need to use 80w-90 gear oil into the transfer case, don't have a manual so, kind of assuming from what I've read on here. Also, anyone have any good tips to avoid having the linkage seize up? Should get enough use so that it never happens, but anyone ever had any luck filling the well of the T-case shifter with gear oil or grease?
