Howdy all. I'm rebuilding my rear Dana 44 axle (3.73, 30 spline), and I'm shopping for a new differential. My '72 Scout II originally came with a Trac-Lok that was replaced years ago by an open differential. I was planning on returning the axle to its stock configuration with a Trac-Lok, but I hear a lot of negative comments about their performance and endurance. I'm looking to spend below $400 or so for the differential, so the Trac-Lok is nicely priced at around $200. However, I don't want to be rebuilding this axle again, and I do want good offroad performance. Any personal recommendations? Any good lockers that are easy to install in the $400 range?
