i recently bought a 92 cherokee, 4wd, automatic hubs, and overall, it is good, i previously owned a 91, and i loved it, but here's my question. when i was test driving it, i put it in 4H so i could get it out of the guys driveway (lots of snow behind it) and it worked just fine, then i decided to test the 4L, i stopped, put the transmission in neutral, and shifted to 4L, and at first it was good, really torquey like it should be, then with not even a sound, (after about 20 seconds),it acted as if it slipped out of gear and was in neutral, (tranny was in drive). then when i tried going back to 2wd (stopped, tranny in neutral) it would grind while trying to take it out of 4L. i eventually got it, but was wondering what would cause the 4L to malfunction when 4H worked properly? im much better at turning wrenches than diagnosing problems

 

The first thing to do is to check the linkage and tighten/adjust it if necessary.

 

ill check it out, thanks
