Q: Front differential not working properly

asked by on September 29, 2016

My 4wd doesn't work, the actuator works and the shift motor works. I lifted the entire truck and put it in 4 hi and the front wheels spin, but I can stop them by hand. There are no grinding noises or anything out of the ordinary. I have just replaced the cv axles and hubs. What would be the problem in the front differential?

My car has 192000 miles.
My car has an automatic transmission.
