I always recommend seeking the services of a professional. The set up of the gears is a very precise task. It takes some special tools and a lot of patience. It's just not worth the hassle/headache/expense for a jod that most guys will only ever need to do once.
Pay a pro and you will get a warranty too.

OK, I understand. Point well taken. I'd like to go Posi. Any advice as to what kind of unit I can replace the current one with? (Years and Truck Specific, etc.) If I'm paying for a rebuild I might as well go for the Posi. Thanks, Al W.
