Question about 1999 Chevrolet Silverado 1500
I own a 99 chevy silverado 5.3 and one day the 4wd just quit working. I have the push button 4wd and the lights come on like it shifts but nothing happens. the front wheels don't spin when in 4wd just the rear driveline. It doesn't make any weird noises and no service lights came on. any ideas?
Jack up the rear wheels and put it on jack stands. Have someone get in it and put it in 4wd and drive. Release the brake. Rear wheels are spinning only right. Don't get under it but look under it and see if the front driveshaft is spinning. If the shaft is spinning but the wheels aren't it is likely a bad front axle actuator. If the front shaft isn't spinning it is a transfercase problem.

a little tip a friend gave me in unlocking the 4wd drive on ramps or hill and then put in neutral let roll back a foot put in park and then let off the 4wd
when in 4wd the hubs get a little heated cause they need greased so they stick into position making it hard to come out of 4wd this which i spoke of i got stuck in the senerio where i almost drove home in 4wd from 300 miles away but i called my friend he told me bought this and so i thought it could help you
your hubs just locked up on you your bearings are going to need to be packed again this is normal for this
