While doing some maintenance today, I noticed that there was a slight leak at the end of the shaft where the driveline attaches. How common is this and how much to replace the seal?
Additionally when I drained my transfer case oil, I found some gold looking shavings. Is that normal? I have some vibration at the back of my jeep but I thought it was because I have 2.5" lift and the driveshaft has not been replaced.
