Front end problems ??

[79 oshkosh 2323]

I jacked up my m37 to do the front brakes. As i spun the wheel after putting it on jack stands i noticed the pinion does not turn. Both wheels spin. As i spin one the other goes backwards witch is normal but no movement in the pinion at all.What should i look for. I know it has to come apart. Thanks

Stop (or chock) the other wheel from spinning backwards while you spin the other, then let us know what happens.

Can you post a picture of your truck? Also what year is yours?

Nice looking truck, don't tell anyone but I like the M37 in red just as much as I do green.

If it has an open diff and both wheels are off the ground that is normal. The rotational force takes the path of least resistance which is to spin diff which rotates the opposite side in the opposite direction. If you lock up the other wheel as mentioned above, the power should then rotate the pinion and driveshaft.

You were correct. I had both wheels off the ground. Im glad i asked i allmost kept going and pulled the diff. Thank you for the help.
