Due to some drive line vibrations on my wrangler, I am forced to look into the source of my issues. Now, whether it's bad luck, or just coincidence; I have been under this jeep at least a dozen times inspecting or fixing things and never saw this. As you can imagine, I got pretty angry at the previous owner and the dealership that surely saw this and probably did the work. 75 dollars later, and I have a slip yoke on order. This is on a 2004 4.0 TJ with an auto and 231 t-case. I can't for the life of me ever think of an excuse to think this style of farm repair is acceptable... It has lasted a year but I really don't trust this to drive on for much more than the short distances it currently is used for. Especially with high speeds. I rarely get to drive faster than 55.
