Wow was i miss informed, i was told that the 91 4DR kicks with the 8 valve had the 12 bolt with 5.38s. that really sucks cause i didnt want to mess with the rear end i just wanted to tweak it. so i guess down the road i can swap in a D44 or something.
But for now i might just put the 10 bolt carrier in and try to be carful. thanks for the info.
If you are thinking you can put a samurai 10 bolt carrier in the rear axle of the trackick.....I don't think you can. The samurai (and trackick front) 10 bolt carriers are narrower (carrier bearing spacing is closer together) than the trackick rear carriers....therefore, I am pretty sure they don't/won't interchange.
If you are going to use a trackick rear 10 bolt carrier, then yes, it will swap in fine.....and I don't think it is really much weaker than the 12 bolt carrier........not really sure why they changed to 12 bolt carriers, AFAIK, the only difference in them is 10 vs. 12 bolts that hold the ring gear on.
