Sorry if this is the wrong place. Have been doing a lot of searching and I am just frustrated. I have a 92 F250 with a 5.8 liter, manual trany with manual 4x4. We turned rear drums and new pads, pulled front hubs and replace inner and outer bearing, races, (everything) used proper lubrication ( prev lube was nasty) new shocks, greased all points, new rotors and pads, cleaned hubs. Put all back together, finally got it back from my brother, first snow fall and BAM no four high. Thought I had low, because it crawls slow, but later tried turning wheels to get it to lope and it does not. When i try and go to 4h while driving, I hear a slight grind, go back to 2h and it is gone. It is a very slight grind noise. I also have a pretty good vibration in 2h when i hit 35 MPH to abot 50 MPH that was not there before, not sure if connected. Checked linkage, it seems to be fine. Jacked up front end, put trany and tc in neutral, get front axle to spin on one side, bound that side up and it transfers to the other side. Any ideas? Im hoping something in the hubs, that was the only thing we really messed with on the 4x4 system. The 4x4 was working last winter.

HELP!

 

manual or auto hubs?

 

Sorry, I forgot that. Manual, we cleaned them and lubed them.

 

Gonna have to take the hubs apart again and make sure theyre working right. That's definitely your issue. Possibly too much lube in there.

Thanks for the reply, that is the route i'm taking Friday morning. Fingers crossed that it's that simple, lol.

 

I've had it happen as well, you probably have one side working ok and the other just free wheeling. Naturally its going to send the torque to the path of least resistance.

Also, check to be sure the actuator that locks the hub to the axle shaft is working properly (the thing that pushes in as you twist from free to lock), that was one of my issues years ago.
