I have a 93 z71 w/ 4x4 auto tranny and Im having a strange problem. While driving either slow or fast I get a random "Bang" noise comming from the transfer case area, (more like someone hitting it with a sledge hammer) It can happen at 10 mph or 70. When it does happen I get a slight jolt of resistance as if the front hubs are trying to lock, I cant say for sure but thats what it feels like? After the noise occurs I'll put it in 4X4 and drive it for awhile and no banging noise happens? after its put back into 2x4 its fine for awhile, then driving over speed bumps or railroad tracks seem to set it off again......... I know for sure its not the ring clip on the input shaft due to a shop looking at it.
I just took out the front driveline and drove iot for awhile and the problem is still there, I guess the next step it to remove the 4x4 swith going into the transfer case?
Anyone had or heard of this problem?
Thanks for any help on this.
