Hello all. Glad to become a part of the community even with the horrible circumstances. I think my front diff may be bad. I have no 4wd. It is not the cad system I know that for sure the ring and pinon gears are fine also I think the splines are fine going into the diff. Also diff makes no noise. But at this point I'm at loss.

 

What year is your truck?

 

2001.

 

Then you should still have the CAD system. Check the passenger side axle tube. It'll be obvious if it is there or not.

 

I stated in the first post that it is not the cad system at all. I manually splined the two shafts together and spun the driveshaft and there was no movement at the wheels

 

Ok, need to include those details when you post, as we have no way of knowing what you did.

I suspect that the collar did not stay engaged.

With the front jacked up, turn the passenger side tire, does anything else turn?
