well what i thought was a bummed t-case is now my front end. my passenger front has been wearing really bad and i cant drive past 45-50 without this weird vibration. the wheel isn't shaking, but just a weird vibration. then stops when i put the t-case in 4-hi. its been getting worse ever since my dumb ass thought i could rock crawl better than my buddy's Yota, and i got hung up on my front drive shaft and it felt like it popped into 2wd. then i messed with it a bit and it went back into 4. any ideas?
