The FNG Posted April 11, 2012 Share Posted April 11, 2012 (edited) Ok, I've got this info for an LSD. Is it right and will it fit my Loyale with a 5spd manual 3.90 gears? rear diff from a 04 wrx. 85k miles, pulled from a salvaged running driving car. will fit all 2002-2005 3.90 5 speed wrx's. will not fit the 4.11 automatics. $100 Edited April 11, 2012 by The FNG Quote Link to comment Share on other sites More sharing options...
edrach Posted April 11, 2012 Share Posted April 11, 2012 No, your rear axles need stubs on the rear diff to fit; the WRX doesn't. Is it a VLSD or true LSD diff? Also, I think you need a 3.900 ratio and the WRX is usually a 4.111. Price is very good if it's a true LSD; you could use the clutch pack in the diff and install it in your current open diff.

987687 Posted April 11, 2012 Share Posted April 11, 2012 The wrx has a 1.1:1 center diff. So it's a 3.90 front/3.54 rear. Quote Link to comment Share on other sites More sharing options...
The FNG Posted April 11, 2012 Author Share Posted April 11, 2012 I suppose I need more info on it then. I was super stoked on the price. If I am correct, there should be a nameplate on the back of it that would specify more info (just like on my Loyale). If there is no nameplate, then how would I be sure exactly what the ratio is, if it is really an LSD (it doesn't have stubs to rotate, just female holes), and what type of LSD it is? Thanks again.

1 Lucky Texan Posted April 12, 2012 Share Posted April 12, 2012 almost certainly viscous, and many folks claim they're toast after 65K. at least, that's what I've read. Quote Link to comment Share on other sites More sharing options...
The FNG Posted April 12, 2012 Author Share Posted April 12, 2012 I think I'll leave this one to someone else. I really don't have time to mess with it. Here is the link: http://portland.craigslist.org/grg/pts/2902723089.html Quote Link to comment Share on other sites More sharing options...
