Does anyone know if anyone is producing replacement stop bushings for the transfer case? They crumble with age and the motor moves the shifter too far and the computer loses track of the shafts position and displays an error when you try to shift in or out of 4WD.

Thread explaining the problem here.

2010 F-150 5.4 FX4.

 

Is that plastic?

 

Yes, and I found another site that said that it can be replaced with a piece of 5/16" fuel line.

 

You could also get a piece of tube and using some red loctite and a press, you can make a permanent fix.
