I bought my wife's wj really cheap cause the old lady said the front axle was going out on it. Turns out it was just the drive shaft! I wound up replacing the 247 with a 231 from a xj. I had to swap the input shaft from the 247 to the 231, but it wasn't that bad. I also replaced the front yoke with a xj yoke, and found a zj front shaft the correct length. The only down side now is the 4wd indicator doesn't line up right now. If i had it to do all over again, I would find a 242 and swap it in cause you can find the shifter bezel that works.
