Odd sound when in 4hi/4lo?
I went on a short drive last night about 3 miles down the road to get some smokes and I noticed this very slight intermittent (has happened before but only after hitting a large bump in the road and sometimes randomly) wobble/vibration in my steering so i decided to see if it was the balance of the tires so I put it into 4HI and noticed this very slight whirling sound coming from under the jeep, can't hear it with the windows down. Its somewhat louder in 4Lo and after I disengage 4wd from either 4Lo-4Hi it takes about 50-200 feet to shut off with a slight jolt.
I do all the maintenance to the jeep and I have the FSM for my model year, any ideas on what this might be?
