[QUOTE="nwwheeler08, post: 1460230, member: 19646"] So, Finally got the 87 Yj with the injected I6 swap, AX-15, NP231 and 8.8 rear w/ lsd. Dana 30 Front with an Aussie. Now the front had that adapter kit installed to lock it in full time. And for some reason it has some terrible vibrations when its in. Spicer U-joints look good. And its a Drivelines NW that looks straight. Any Ideas? Also for the rear, its got an SYE kit with another Drivelines NW double caradine or whatever cv style. Now when under load theres a vibration. It feels like its coming from the driveline or tcase. I know the Rear diff isnt at the right angle but if it was a driveshaft issue, wouldnt it be all time not just under load? I put the rig on a lift, started it and ran through first and second gears without the vibration. Im going to take the rear shaft out and put in the front this weekend to see if the rear noise goes away. Thanks Ahead of time for ideas Guys! [/QUOTE]
