Horrible Noises When Shifting 4wd
A couple of days ago I took my Jeep out to this vacant lot down the street. When it rains there are big puddles and stuff and living in the city it's nice to be able to get a little bit of mudding in. So I had it 4hi when I did this, and on the way home I put it back into 2hi, where I heard a rattling sound coming from underneath. I got home, then started to go to my girlfriend's house, and on the way down the street the rattling got worse and louder as I increased my speed. I put it into 4hi again, and the rattling got quieter, and so I put it back into 2hi and got a horrible grinding sound that was loud enough to echo down the street. I put it back into 4hi, turn around, come home and take my other car to the oldd lady's house.
So today I'm trying to figure out what's going on. It will shift into 4lo, but I hear the rattling noise again. And if I go 1-3 mph I can drive in 2hi, but I can't go into reverse without a loud scraping/grinding noise. I can reverse in 4hi. I checked the u-joints on both driveshafts, and they're solid. The shift linkage may be the problem, as said on other posts, but I feel like it's something inside the transfer case because it will shift in and out of gear, but just get scraping noises after I shift into and apply the gas.
I'm gonna have an entirely new TJ by the time I fix everything that's gone wrong in that damn thing.
