FSJ Differential Carrier Lim-Slip on TJ Dana 44

I have a bent DANA 44 carrier on my TJ 01. I found a DANA 44 loaded carried in a FSJ website, will it work / fit on my jeep?

Yes it will but I never heard of a bent carrier. I think the JK dana 44's did not start till 07. TJ d44s are regular standard cut d44 gears with the standard d44 carrier.

I was also surprized when i heard the mechanic tell me i have a bent carrier.. what happened exactly was the teeth on my ring and pinion got chipped while i was driving on asphalt. When i baught new ring and pinion set, it did not fit on the carrier, I took it to a machine shop to check the dimentions and see whats wrong, he told me that the carrier is bent, this is why my ring is not fitting it. does that make any sense?

Must've bent the ring gear mounting flange? At any rate... the FSJ carrier would physically fit your housing. Both Jeeps use a 30 spline D44. However, I see in your profile that you're running 4.56 gears. If the FSJ carrier is stock, it is probably for the 3-series gears (up to 3.73). If that's the case, you'll either have to run a "ring gear spacer" or run the "thick" 4.56 gear setup. Just something to keep in mind.

Thanks BESRK, that was really helpful, the part I am getting is not stock, it says in the description that is suitable for 3.92 and up gear ratio.

My brother warped the front diff carrier on his 68 CJ-5when he broke a ring gear tooth. Apparently the broken tooth got caught between the ring and pinion and warped the open diff case. So it happens. You might check the ring gear bolt size on your old carrier and any new one you intend to use. Dana went from 3/8 to 7/16" bolts on 44's in recent years. Foggybottombob mentions the JK 44. As I understand, the rear of those are a totally different axle and should have been renamed--bigger ring gear, bigger pinon shaft among the differences.

i think i've got a bent carrier also...78 Buick Regal 7.5" lim slip 3.23; broke the pinion teeth; when installing new ring & pinion the backlash was huge on one side & zero at 180 deg rotated. my thought is that pinion teeth got between gears & bent the carrier. now the job isnt 250 but 400 more for an auburn lim slip carrier. that shift kit in my TH200 behind a 4.3 with 4 bbl tore that **** up!!! bottom line; if you broke teeth, chances are that it bent the carrier. i'm surprised i don't see more posts about this
