Hey all, I have a plow truck that I've been working on. I got the truck and the 4wd shift lever was seized. I soaked it for days and I finally got it free today. I shifted the truck into 4 low, and put the plow down and chucked the wheels to see if 4wd was actually working.

The truck spins the front driveshaft and the passenger side axle spins. The drivers side looks like it tries to catch but makes a faint ratcheting sound an doesn't catch.

I'm automatically assuming that it's the ****ty factory automatic hubs. Whats everyone think? What's the best place to get a manual hub conversion? Really hate this 2wd plowing deal lol
