99 TJ, 50k miles, still has stock driveshaft and no lift. On the rear slip yoke it has a little bit of rotational play and I can push side to side on it and feel a little play. Is this normal? I've felt the slip yoke in the front drive shaft and it doesn't have play in it, but it's a different kind of setup than the rear. Just wondering if the rear was suppose to feel like this?
