I have a rock krawler 3.5 with a je reel 1350 drive shaft and just got under the jeep after doing the rubicon and at the u joint it was hitting the tank skid enough to dig into it about .25 inches. With my stock flange it hit just a little but it is bigger. When it is just sitting on level ground it looks like I have plenty of room. And also I have the 3 link in the back. Any help would be appreciated.

 

double check to make sure that your axle is centered? more than likely, you're off a bit and when flexing on the trail, your drive shaft swings over and hits your tank. i've seen this happen a lot.

 

...this does not sound good

 

Thanks a lot. I will check tomorrow.

 

Just checked my rear axle and it was off about a .25 inches toward the gas tank. I moved the track bar two turns out and it looks like it is 1/8 of an inch the other way. It seems to drive all right. I thought it would be better to cheat it to the left a little sense I had that problem. Do you think this make sense and was that enough off to cause me to hit gas tank.
