Last weekend I did an SYE on my 2002 Jeep TJ. After the install, I drove it from Columbia to Greenville (2 Hours, no problems). Then on Thursday I drove it to Spartanburg to Carolina Driveline to have the rear driveshaft made and the front re-tubed. When they got under it to do some measurements, they pointed out how hot the rear yoke was. They thought it may be because it is so close to the muffler and there is no heat shield between the two. After some thought, I started to wonder if I messed up inserting the oil pickup tube into the oil pump inside the t-case when doing the SYE. So I convinced myself to crack it open again. I drove it back to columbia and opened it up. I took the yoke off and then just the back tail housing. From there I could push the oil pump up and see that the tube was seated. I even took some needle nose pliers and made sure. Then I even turned the t-case by hand and confirmed it was pumping oil. So, I put it back together. Then I made a heat shield that separates the muffler and t-case along with the yoke and top part of the driveshaft in an attempt to block the heat. I started the jeep and let it run and the heat shield worked well. So, back on the road to Greenville. I drove about 15 minutes and stopped for food. I checked the yoke again and sure enough, it was very hot again. What is going on? Is this something I should even be concerned about? I just have this bad feeling that this is a sign of something bad to come. Anyone?
