Hello all
I have a 1992 k1500 single cab 5.7 l v8
I recently had the old front drive shaft installed, bolted in front and back. But the 4wd still isn't working. Is there anything that Im missing?
All the help would be great!

 

If the fuse is good,the actuator on the front end is the next thing to check. Check the plug for power with the key on and shifter in 4x4. If it has power, unscrew the actuator and see if it extends. It's common for a bad actuator to blow the fuse so you'll want to keep an eye on it.

Why was the drive shaft removed?

 

The truck was rebuilt so the guy didn't put it on in time before I bought it. And thank you! I'll check into that 👍
