Bent NP231 output slip yoke
My jeep is built for rock crawling, so when I took it to some local dunes, I bottomed out the suspension a number of times. I developed a bad vibration that is noticable at all speeds, and starts howling and vibrating like all hell when I hit 70mph. I took the rear drive shaft off and put the transmission into gear with the engine on to turn the splined out-put shaft. I found that there is some wobble in the shaft, so is the shaft bent, or is the problem inside teh t-case? I ordered a new shaft today but after I ordered it, I realized that the problem could be in the t-case itself, not a bent shaft. Please help! I plan on eventually usaing the rubicon express sye, if that makes any difference.
