Got my LSD fix today
Posted 15 August 2009 - 01:05 AM
However, I have a few after-the-fact questions:
1. I overtorqued the bolts that hold the ring gear to the LSD carrier unit. Factory spec is like 58lb ft i was told, but that was after I torqued them to 90lb ft ... Is this going to be a problem?
2. I am not a rearend/tranny specialist, and have no clue how to check backlash. When I swapped the LSD into the 3.9 housing, I used the shims that were installed on the housing when I took it apart and I put it back on exactly like I found it. Should I be worried about grenading my pinion gear? Everything feels good, no slop, nice and smooth motion...
3. I used RTV silicone to make the rear cover gasket... Because Im lazy and impatient and did not want to wait another week for a gasket from the dealer... No problems there right?
4. I used Genuine Subaru LSD oil in it (all the writing was in Jappanese so I couldnt read it :-\), I just filled the diff with it untill it was level with the fill plug. I wasnt supposed to mix it like 50/50 was I?...
I got really lazy about this whole piece of the project, I did not clean and paint the housing or polish the cover or put on a custom 3.9 LSD sticker... Its ugly, dirty, and no one would tell by looking that its LSD, But I now have an LSD that will see lots and lots of mud and trails I hope... Cant wait to try it out! Ill test it out this week and then put it to the real test at Evan's Creek

never done one, but the few i've read about, folks just put them together like they found them so to speak like you did.
i have to do the same thing before winter, how long did it take you? an hour or a few?

Now its time to weld up the 3.9 chunk and put it in one of my Brats

great, should be about the same for me, sounds EXACTLY how my work usually goes!!!
All in all it took me prolly 3-4 hours of looking at it, kinda-scraping some dirt, looking at it, taking some parts off, looking at it, spilling 6 quarts of used diff oil all over my power tools, looking at it
