well ive been trying to rebuild my t-case the last month or so along with a sye kit. right now i have 242 in my jeep and im switching to a 231. now we ran into a problem today. when i shift the lever on the t-case into 4wd it works perfectly but when o shift it to 2wd the gear is still hitting like it were in 4wd, does anyone know what the issue could be.
