\'93 k1500 Front Drive Train Clunk
I'm tryin' to figure out what's wrong with my friend's '93 K1500. The truck is completely stock. He recently put on a new front diff actuator. While driving at highway speeds in 2wd, we hear a clunk and feel a 'grab' in the front drive train, like the front drive shaft is trying to start spinning. Would this be the actuator getting a voltage signal from a bad switch on the transfer case? Or would it be the actuator is not retracting all the way? The problem is not constant. There's no way the T-case could be trying to slip into <nobr>4wd
</nobr> without the lever being moved, is there? The '93 uses a switch on the T-case to control the actuator, no dash switch. Our next step is to run it with the actuator removed, to see if the problem goes away. Any ideas? I did a search but it didn't find anything specific about this problem.
