What up you guys! My rear end has been screaming at me ever since Ive owned my truck. I just ordered a master rebuild kit for my 99 auto 47RE with the dana/spicer 70. I'm trying to figure out what carrier clutches to order? the Kit did not come with the carrier clutches and I want to replace them. Reliability is the number one most important thing for me, but posi would be cool. Any suggestions would be greatly appreciated! If there has already been a write up on this Im sorry i could not find it. Thanks in advance

Man, that is one thing I'm glad I've never got to do. Open diff just change fluids and drive on. 

I used spicer clutches with the lube they supply. When you get the clutches they will say thin on some make sure you get the config correct also the steels are coned make sure they go in the correct way.

You've been lucky from what I read mopar1973man, sounds like proper maintenance is key. The kit NIsaacs mentioned is a dana/spicer kit and I think I'm going to order it.  Anything I should be aware of before I order? I really just want to make sure it fits. Im sure they come with instructions for proper install but if not, lol you all will be the first to hear about it. Thanks 

Spicer kit only.  Power-Lok parts are getting harder to find and Spicer kits are a guarantee fit
