NOTE: This info only applies to the SG generation (for now)

Ok, the info is strewn all around so let me try to collect the stuff I need..

In regards to our rear diffs, tranmissions, part numbers and ratios... (please correct me!)

-Opposedforces lists for the XTs (4EAT-LSD):

Differential assembly-rear 1
27011AA541
4.444 VISCOUS LSD
'03, January — '04, March
4.444 VISCOUS LSD
'03, December — '05, March

27011AA730
4.111 VISCOUS LSD
'05, January — '06, March
4.111 VISCOUS LSD
'06, February — '07, March
4.111 VISCOUS LSD
'07, February — '07, November

-4EAT XS, which also has a LSD rear diff, utilizes the earlier LSD PN, 27011AA541.

-5MT XTs also seem to be using 27011AA541.

-5MT XSs, on the other hand, use 27011AA730.

-5MT X (non-LSD), uses:

Differential assembly-rear 1
27011AA343
4.111
'03, December — '05, March
4.111
'05, January — '06, March
4.111
'06, February — '07, March
4.111
'07, February — '07, November

-4EAT X (non-LSD), uses:

Differential assembly-rear 1
27011AA413
4.444
'03, December — '05, March
4.444
'05, January — '06, March
4.444
'06, February — '07, March
4.444
'07, February — '07, November

-LLBeans use the same as the XSs.

Note: Manufacturing date can be found on the driver's side between the front and rear doors above the rocker moulding.

So essentially, if I was looking for a replacement rear diff for my 05 4EAT XS built in 12/04, I should be looking for a 5MT XT rear diff. Am I getting this correct?

So...
5MT XT - 4.44 LSD
4EAT XT (MY04/05) - 4.44 LSD
4EAT XT (MY06-08) - 4.11 LSD
5MT XS - 4.11 LSD
4EAT XS - 4.44 LSD
5MT X - 4.11 non-LSD
4EAT X - 4.44 non-LSD
4EAT LL Bean - 4.44 LSD
5MT LL Bean - 4.11 LSD
08? 4EAT FSX - 4.44 non-LSD (-AA413)
SH 4EAT X, X PLUS, X LTD - 4.44 non-LSD (-AA413)

Can someone chime in on which Legacy rear diffs also work for us? I think the 99-02 Legacies shared our components (shows you how far behind the Legacy family we are!).

Cool list, thanks. I was also told that if you installed a rear diff with the wrong gear ratio, you will find out within a hundred feet, the hard way.
