I think the CTM U-joints are the ones with rebuildable bushings but they are expensive, like $150 each, mabey more. Depneding on hold old your U-joints are you either have the old 297 or the newer cold forged 760. They are both the same size, but the 760 is something like 30% stronger. You have a few choices for brand, Spicer, Alloy USA and parts store brand. Alloy USA has the best warranty, 3 years. Alloy USA also has greasable caps, which are stronger then the greasable body style. I am a little bias since I just put the Alloy USA ones in my YJ, but I did some research first and for the $$ they can't be beat. By far the best deal is Northridge 4x4. Give Dave a call and he will hook you up. I paid $29.95 each for mine, just tell him you are part of JT 4x4 in CT.

www.northridge4x4.com While you are in there I also recommend getting a set of out axle seals since water and mud can get in the housing all the way to the seals by the pumpkin. They are easy to instal when the axle shafts are out. I paid $60 for a set from Northridge.
