 Rear is most likely a 35 but a lot of TJ's did have 44's. Look at the tags on the cover and it will tell you which rear you have and the gears. Rebuild is the best and cheapest way to go,and also good time to add locked.

35=rubber fill plug                44=threaded fill plug
You may be able to buy a complete used axle for less than a rebuild, depending on what you need to replace. If your just putting new bearings and seals and your doing it yourself than a rebuild would work. But if you need R+P side gears etc. junk yard may be the ticket.
More info would help. (tire size, rear end type, dif. ratio, manual or auto, 4 or 6 cyl.) Maby this is the time for a gear drop, but dont forget about the front end if you change rear gear ratio.
