Ugh ja that ring gear is toasty :o  big job to replace.  On the 6.9 you have to pull the engine and trans which in itself is no walk in the park.  Best to bang out other jobbies while it's out.  Bon chance ;)

Yes, spot on.  Prepare yourself for some soul searching on how much work you want to do when engine is out.  It's such a great opportunity to do jobs you'd probably never consider otherwise! 

Anyway, if you do pull the engine make sure that your engine hoist is HUGE.  It's not just a question of weight.  The boom needs to surprisingly long or you'll eventually get stuck.  Also get a good, heavy duty leveling arm.  The cheap ones with small threads (such as Harbor Freight) will wear out surprisingly fast.  With the right equipment pulling the engine really isn't as bad as you'd expect, though it is laborious.  With undersized or cheap-o equipment there's a very high risk of something very bad happening.  Don't ask me how it know this.   ::)
