Re: Pros and Cons of change to Posi rear?

York, you live in the "snow belt" just like I do. Seeing as yours isn't 4WD I would swap rear axels and be done with it. You don't want to tangle a$%holes with trying to swap parts around inside an axel unless you know what your doing, trust me. Every rear axel is different, even 2 going down the assembly line one after the other. Pinion depth, ring gear backlash\clearance, bearing preload, not to mention bearing replacement. It's a lot of work thats sometimes very tedious and sometimes frustrating. Get it wrong and she will howl something awful, and possibly destroy itself. I did it for 33 years and have a Detroit locker posi unit sitting in my garage I was going to install but the work involved dosen't justify changing from an open rear because I have 4WD. Jim

Little stuff left to do is mount winch, wet sand & buff out and build belly pan\running boards. Body work takes lots and LOTS of beer!!!! God, Guts and Guns made America and God, Guts and Guns will preserve it! The worst thing you could do is get into my sights, but that don't matter, you'll never know it, cause you'll never hear the shotJim or Paladin whichever you choose.
