Fresh meat here... and I'm elbow deep into the g52 tranny from my 84 4x4 pickup(180k mi). After a lot of deliberation I have decided to rebuild the tranny myself, I have time on my side, solid mechanical aptitude, and the guts to give it a try. So riddle me this...Background: A few years back fifth gear began making a whining sound, due to economic issues and such I just turned the radio up at highway speed. Now after a recent road trip all the rest of the gears, except fourth, have taken on a similar note, and I decided to do something about it.I have seen some bits and pieces about a common problem with G52 fifth gear, and a fix it kit, but nothing definitive, such as a source for the kit or a solid explanation of the problem. I have come to the conclusion that the universal gear noise is caused by a worn out input bearing, but of course I could be wrong. In addition I have seen different opinions about break in procedures, mineral oil for the first 10K, then go synthetic. Or just go top shelf synthetic right out the gate... Also a friend told me to not reuse the old snap rings, does anyone have an experienced take on this?At this point I have it down to the intermediate plate with all the gears still on it, shafts and forks removed. There is no sign of gear damage, just fine metal shavings. I assume I will come across any bearing wear as I check play and what not in the next couple days.I have a MC minor rebuild kit, FSM, and have sourced new snap rings and pretty much all the internals I may need, so I'm just looking for thoughts on what I have mentioned or any other good ideas about the G52.Thanks folks.
