So I had the same problem with my 2006 H3 that many experienced: the refusal of the car to turn even 90 degrees at slow speeds. This forum helped me see that it could be the melting shift fork in the transfer case issue. So 2.5 years ago I had the better metal one put in...costing about $500. It worked perfectly! The turn radius was impeccable and no more resistance existed. So just 2 days ago, it decided to revert to its old ways and now I'm stuck again without the ability to maneuver in parking lots or make u-turns. Could the metal shift fork have melted too?? How many times does one have to replace the shift fork?? Thanks for any advice!

 

The plastic fork issue was not because of "melting". No your metal fork is not melted either.

Go to a parking lot, shift to 4Hi Lock & drive forward a short distance. Stop, shift to 4Hi and drive backwards a short distance, see if the condition continues.

On occasion, any T Case can get stuck in Hi Lock because of pent up Torque not allowing the lock to disengage. Driving backwards and turning back and forth can unwind that stuck condition.

 

Thank you so much for your help. I tried to do as you said, however, and it has not helped. Do you have any other suggestions?

 

You may have a boogered CV (half shaft) on one side.

Did you check the boots to see if there are any cuts or cracks in them? Any grease trails on the underside near the Half shafts?

Just a thought.
