I'm no mechanic so I can't completely answer your question but I wanted to pass along a little info.
Does your truck have the 3.92 LSD rear? If so, some of the third gen trucks with that rear have problems with some sort of c-clips (I think it's called) breaking off in the rear end. My understanding from doing research is that the clips basically hold the entire gear set in the proper position inside the housing. If the clips break off or come loose your truck may still operate normally as long as one of the clips doesn't end up in the gears but it will cause wear over time and some have had to replace both the gear set and the entire rear end housing because of this wear. Don't let this freak you out....I'm not saying that you have this problem. I just wanted to pass along some info in case you weren't aware already.
I thought about pulling my diff cover myself but I am going to take mine to the dealer after the first of the year and let someone who knows exactly what to look for take a look at it. If you do it yourself I would just look for any loose metal pieces or chunks in the old fluid that comes out or in the bottom of the diff housing. Let us know what you do and how it goes if you don't mind.
