'96 Blazer 4x4 problem

Hello, I searched all the other post's and couldn't find the answer to my problem. I have a '96 Blazer, The 4wd dosen't work. I press the button on the dash for 4 hi, the light goes on and I hear the transfer case lock in, I had it up on my lift in drive and the rear wheels turning. I figured it was the 4WD Actuator under the battery so I took it out and found a rip in the diaphragm. I figured before I go out and buy a new one I would try pulling the cable to see what happens, all I get is a grinding noise from the front end and the front wheels do not engage. Any Ideas? Thanks!!:banghead:

If you have all 4 wheels off the ground, and the rears are turning, the front axle will grind and not engage. (Front and rear wheels need to be going the same speed.) Put the transmission in park or neutral and try it.

Old Master You are the king! I never even thought of that. I will try it tomarrow and let you know how I make out. Thanks!!!

Hello, Again I replaced the 4wd actuator and every thing seams to work good! I want to say thanks again this forum is always very helpful! Thanks!!! :iceslolan
