Blue88Comanche Posted December 28, 2016 Share Posted December 28, 2016 I have C/V shafts from a v8 zj. I don't do any hard wheeling, but I like the handling when making sharp turns. If you are replacing just the u-joints you gotta take out the shafts anyway. Sent from my iPad using Tapatalk Link to comment Share on other sites More sharing options...
Crash Posted December 31, 2016 Share Posted December 31, 2016 ABS shafts or late model D30 shafts use the 297 joints that you can run spicer 760 joints in. Link to comment Share on other sites More sharing options...
Incommando Posted December 31, 2016 Share Posted December 31, 2016 If you don't change axles you are limited to the stock 260 series u joint. Just run spicer and call it a day Link to comment Share on other sites More sharing options...
DirtyComanche Posted December 31, 2016 Share Posted December 31, 2016 I bought ZJ CVs because I had damaged 260x shafts. So far I like them but don't have a lot of miles or abuse on them. I think they're probably all around better than the 260x shafts and aren't a lot of money. Personally I would never bother changing a set of 260x ujoints. Junkyard some newer style ones, or buy aftermarket. Link to comment Share on other sites More sharing options...
Jeepman Posted December 31, 2016 Share Posted December 31, 2016 ABS shafts or late model D30 shafts use the 297 joints that you can run spicer 760 joints in. This is the way to go if you want to stay U-joints... Personally I got sick of changing u-joints every year or so and switched to ZJ CV shafts and never changed one again in my MJ and ran the same CV shafts for the next 6 years till I did a Hub conversion and had to go back to U-joints but they were the 297's and a locker but rarely had the hubs unlocked...

DirtyComanche Posted December 31, 2016 Share Posted December 31, 2016 To do everything over again I'd probably just order RCVs. But then again, I like spending money foolishly. Link to comment Share on other sites More sharing options...
mikekaz1 Posted January 1, 2017 Share Posted January 1, 2017 I like my CV shafts. No issues here. Link to comment Share on other sites More sharing options...
