Searched but didn't find an exact match for what I'm seeing here. Hopefully someone can shed some light on what I might be looking at.
2001 Sport, NP231, D30/35 front & rear.
Last night I hit a rock spill hard enough to shred the passenger rear tire and put a slow leak in the passenger front. At the time, I was in 4HI. Changed the blown tire (at midnight, in pouring rain), drove the 20 miles home, parked. Everything up until now felt OK.
Today I come out and get in the Jeep. Noticed something new and exciting: 4HI engages as per normal (driving on light mud), but doesn't disengage immediately when shifting back into 2HI. It takes about 300-400 yards for this to happen, during which time you can still feel the front axle pulling. When it does disengage, it does so with a fairly noticeable bang and a feeling like you've driven over a speed bump too fast. Note that the shift from 4HI to 2HI feels normal, it's just the disengagement of the axle that feels odd.
I haven't got under the Jeep to look for damage yet due to the weather, but is there anything obvious I should check for that might be causing this? I'm thinking it may be a vacuum problem, but would like to hear suggestions before getting my hands dirty.
