RX Leone LSD Diff.

[AlpineRaven]

I've sourced an RX Leone rear diff (not recently, ages ago), yes its 4.11 LSD from an Automatic RX Turbo. Now I wanna to know if I could change the crown from 41 teeth down to 37 teeth to match the AWD gearbox. Can it be possible to do that myself at home? or do I require special tools? Will the bolt holes fit? (I'm getting the 37 teeth crown from an 89 L series wagon) as my rear diff that I'm suspicious that is worn out as it makes whine noises, and while I am changing the crown over, is there any notices that I should do while its taken apart ie. New seals etc?

Thanks

from the ultimate subaru repair manual. it refers to 3.7 and 3.9's but those are for the turbo lsd, and open respectively here in the US, just follow the same directions, but with your 4.11, and 3.7 (or whatever you'rs is).
