How to troubleshoot 4x4
Hey there,
I bought a 98 gmc 1500 5.7L and the 4x4 does not work I was wondering how I go about troubleshooting the issue to find out what the problem is? I was told by the seller its the transfer case but i was talking to my friend about it and he doesn't think that's the case because it isn't grinding when I put it into 4h or 4L. There is a manual shift gear inside, not lock hubs. Please help as I am a self taught mechanic that doesn't know a lot but willing to learn!
Thanks in advance.
Is this a good question?
this is a common problem on these trucks i would be surprised if its not fixed already. Most likely you have a problem with your 4wd actuator either the thing is full of mud, wires are broke, like the one i had was it was stolen so just look up a youtube class on it buy you one and replace it they are about $50-60 now 12 years ago when i bought one it was $350
