aartod Posted May 30, 2008 Share Posted May 30, 2008 My rear end on my 90 legacy started "howling" yesterday... I assume it is the rear end and not the wheel bearings because the noise does not change while cornering. The noise increases greatly while decilerating (I think because of the differant load put on the rearend)... So, to get to the point, what rear ends are interchangeable? And another question, is there anything I can do to to keep it alive alittle longer? I dont have alot of time to work on it right now! Any advice would be great!!!

bulwnkl Posted May 30, 2008 Share Posted May 30, 2008 Thicker gear oil will help keep it a little quieter for now. So, if you're running 75W-90, go to 80W-90, 75W- or 80W-110, or maybe even 85W-140. Link to comment Share on other sites More sharing options...
aartod Posted May 30, 2008 Author Share Posted May 30, 2008 BY the way, my car has a 5 speed... What years of legacys had the same rear end? Are the loyale or impreza rear ends the same? Did all of the legacys around 1990 have the same gear ratio? The local junk yard wants about $200 for a used one... I think I will search craigslist!

aartod Posted May 31, 2008 Author Share Posted May 31, 2008 I changed the diff gear oil and replaced it with 85w and there was no change in the noise... so much for the easy way out! Link to comment Share on other sites More sharing options...
aartod Posted June 2, 2008 Author Share Posted June 2, 2008 I was crawling around under my car looking at all of the possablilitys for the source of of my problem and I wiggled the drive shaft at both ends looking for freeplay of any sort and I also shook and wiggled the center support bearing and now the noise has dissappeared.... I am quite sure that it will be back, and now am not so sure that it is the rearend that is the cause of my problems! Link to comment Share on other sites More sharing options...
