vica153 Posted October 29, 2009 Share Posted October 29, 2009 After dismantling my rear differential I noticed that the 2 gears that mesh into the spider gears, 'side gears' maybe, are different heights and i have no clue which way they go back together. Does anyone have a diagram or exploded view of one of these old diffs? This one is supposedly the LSD from a late 80s XT. Link to comment Share on other sites More sharing options...
idosubaru Posted October 29, 2009 Share Posted October 29, 2009 i don't know about your problem, but XT rear diffs are the same as all other EA/ER series rear diffs. there are a number of LSD conversion threads with pictures of the guts and such, search for those if a pic might help.

vica153 Posted October 29, 2009 Author Share Posted October 29, 2009 I have been searching 4 different subaru forums as well as google and have yet to find a diagram of the diff internals. Photos of people taking the diffs apart, while very cool, don't really illustrate the small difference in side gears. Link to comment Share on other sites More sharing options...
vica153 Posted October 29, 2009 Author Share Posted October 29, 2009 (edited) One side gear is 1mm longer. Either way you put the side gears in, there is 1mm or so of play in the side gears. It looks like the 1mm longer side gear would keep the spider gear assembly from shifting that direction Edited October 30, 2009 by vica153 Link to comment Share on other sites More sharing options...
