What kind of differentials is everyone running?

I've got the stock traction lok in the rear and open in the front.

Lookin maybe at upgrading to an Eaton posi in the rear. I have some bad chatter now..

Any suggestions? 58k miles

 

I'm runnin a Detroit True Trac in the rear, open in the front with 4.10:1 gears.
gets the job done for me!

Wonderboy how do you like the true trac? Thats what im thinking of now. I like the fact it doesnt have parts that wear out....
