Here is the jdparts pic and parts (cover and shaft) if you want.

Robert,

Here is a picture of the drive shaft on my JD770. Should be similiar to what your JD790 should look like. I would recommend that you not use your 4WD until that shaft is fixed or replaced and a new cover installed.

OK Guys. Thanks for all of your help. I now have the front end/driveshaft problems fixed. See pic. Ran me about $320.00 for parts. If I knew then what I know now I could have saved about $60.00 by making the tube shield out of 2" electrical PVC. Oh well...live and learn. Thanks again for all your help.

Robert,

If you haven't already, there is a lot of information on this forum to read about how to best operate your JD790 to reduce the risk of breaking the front gears.

Yep...and one good thing to remember is the tractor is better at pulling heavy loads going forward, rather then backing up.
Another...use adequate ballast on the 3PH when you're using the loader.

IIRC, those gears in the front differential cost another TBNer about $1500.
