If so it’s not the transfer case encoder. 2. At that point I would expect it could be the actuator located on the front differential. This actuator simply pushes a pin in and out to engage the front axle. Take if off and push the 4WD button to see if it is clicking as if to move the pin in and out. |

okay so i took a look at the front drive shaft and yes!. it still rotates but no 4x4! so im going to check out my actuator. thanks for the help! also in my truck i don't have the 4x4 button i have the stick on the ground. And if u could let me let me no if there could be any thing else that can cause this problem?

| im having trouble finding my actuator, where is it located? is there somehow you could send me some kind of diagram of the front differentials? i cant find any pictures online. beacause im more than sure that i did not blow my front axle out. i had just used it perfectly fine last week. also, if i have a stick for my 4wd does that mean it's called mechanical? | |
I have a 1994 Z71 4X4 auto. the other night I herd a soft ginding noise like the pinion shaft hitting my flywheel. Now its loud and only does it when you take off from a stop. Only for two or three seconds then just befor trans shifts into second gear. I thuoght my starter was letting the shaft hit flywheel but I had afriend ride with me and he said it was my axle but it dont sound like it s from there it sounds like a external noise and close to fly wheel locatiom more towards the right side where starter is . OH this is good when I put it in 4 high the noise goes away..please help me .

if my actuator does not engage will that keep my 4wd light from not turning on?
