I bought a 90 Cherokee 5 Speed 4WD. The PO put a custom long arm lift kit in the jeep and i noticed that he does not have a SYE. I also have a Ford 9" rear end and PO decided to tip the rear axel back (pinion upwards) in order to keep the driveshaft angle the same. I am getting a new driveshaft made up since this one has a rather large dent in it and im wondering if i NEED a SYE to go with my setup or if i will be okay just getting a new driveshaft made up. Do i need a CV axel? Also i noticed that my slip yoke isn't allowing my driveshaft to go in and out. Currently i have the driveshaft removed from the rear yolk but it wont come out of the slip yolk. Thanks
