Al_SemC Posted October 17, 2005 Share Posted October 17, 2005 I'd like to both replace my leaky and noisy rear diff with an LSD unit since it's crappy 8 months out of the year here. Does anyone know if they made a 4.444, i.e. AT rear end with limited slip? I recall reading something about a "Cold Weather Package" for the Outback and an LSD being part of it, but I can't find that now. Furthermore, if one exists, does anyone have one they'd be willing to part with? Link to comment Share on other sites More sharing options...
Dr. RX Posted October 17, 2005 Share Posted October 17, 2005 To answer your question in the title, yes it does. Now, if you are going to put one in your car, does the transmission that is in the car have a 4.444 ratio? The front and rear need to match, unless the center diff compensates for the difference.

NoahDL88 Posted October 17, 2005 Share Posted October 17, 2005 I believe what the good doctor is trying to say is, some of the newer Subies have a 1.1:1 center diff ratio, so you will have to make sure that the rear diff you mate up to your transmission is correct as far as if it came from a 1:1 or a 1.1:1 transmission Link to comment Share on other sites More sharing options...

Al_SemC Posted October 17, 2005 Author Share Posted October 17, 2005 I've got a 4.444:1 ratio on both diffs like a normal Legacy AT. Only the older WRX had the 1.1:1 drop gear in the transfer case, AFIK. Link to comment Share on other sites More sharing options...
blitz Posted October 17, 2005 Share Posted October 17, 2005 Seems like a lot of the Subes assembled for North American consumption in recent years spec a 4.111 final drive, whereas the 4.444 number is more prevalent elsewhere, Ozzieland, NZ, etc. Link to comment Share on other sites More sharing options...
Al_SemC Posted October 18, 2005 Author Share Posted October 18, 2005 4.111 is the final drive ratio for a few 4EAT Imprezas (93-01 Impreza w/ 1.8L and 2.2L, the 02-03 Impreza TS, Outback Sport and the 02-03 WRX). It also happens to be the final drive ratio for the 96+ Legacy Outback with the 5MT. According to my FSM, I've got a 4.444 front and rear end ratio. From what I can tell, the 00 and 01 Impreza RS AT models had 4.444 end ratios and LSDs equipped in the back. Looks like I'll need to find one of those dead. ...anybody got one?
