Revived this older thread. Who here has had their JK re-geared that only replaced the D30 carrier? I'm speaking to the members with stock 3:21 gears. I have read threads advising of the rear D44 carrier being replaced and the opposite of that. I have been told and read the rear Dana 44 carrier break is 3:73/3:92. I have also have been told and read there is no carrier break for the rear jk Dana 44. Many ring and pinion suppliers only advise on the front Dana 30 carrier needing to be replaced.
As you can see her Yukon has a carrier break for the Dana 30.
And here Yukon advises there is no carrier break for the rear Dana 44 (non rubicon).
Just wondering others experience and opinions on the matter. I am very curious what you all have done and the longevity of the route have taken.
