Yes, If you have the NP 203 transfercase, there is a kit to either change out the planatary gears item 20 or the rear shaft assembly in this picture: http://www.drivetrain.com/images/sto...3_p1_large.jpg

A good write on this page: http://coloradok5.com/milemarkerpt.shtml

The upper shaft kit is far superior to the one on bottom in strength but is also more expensive.

While you are in there it would be good to check chain wear and change if stretched.
