In a 1993 Jeep Grand Cherokee LTD when you go to turn a corner the back tires skip and the front will not disengage what do you do?

Answer 1

It's your viscous coupler. That part is located in the rear housing of your transfer case. Likely there is nothing wrong with the transfer case itself, these couplers are a wear item and do not last forever. Mine went at 203,000 miles. You can replace the coupler and avoid the cost of a new transfer case. It's possible to replace it with the transfer case still in the jeep, that's how I did mine. Or you can pull the whole unit if that's something you're comfortable with.

The replacement procedure isn't difficult but reaching the snap ring can be a bit tricky with the case in the truck.
