Redneck locker install & pattern check

That's good in theory, but it rarely works. It seems to always throw BL off one way or the other as things tighten up. I think everyone thinks that it's perfectly centered when it's loose and it's not.

If you think about it, the reason is that you can’t have negative backlash. You could remove all of the shims on the pinion side of the carrier, and the backlash will never go blow zero. In other words, the ring gear always stops moving toward the pinion when it contacts the pinion.

In his case, you are correct since he started with zero backlash. In general though, people will set up gears (with correct or some backlash) and keep the carrier somewhat loose so they can pull it out easily when they are doing setup. Then they think they can add an equal number of shims to both sides and get the proper preload without changing the backlash. I have seen it enough times that it isn't the case 99% of the time. In theory, yes. Reality, not so much.

Good point,but it has to start somewhere

My point is that when you set up gears, determine what is proper carrier preload before running a pattern. My cases go in tight every single time. That ensures consistency on the final setup. I don't add shims at the end. It's the same reason patterns will show a slight variance when swapping from setup bearings to your final bearings. Don't get me wrong, these changes aren't huge, but they are definitely noticeable and can be quite frustrating.

I don't disagree. It's just too late for any of that

So you want to help me throw a lunchbox in the front, and a new set of gears so I am not a snail on the highway with my 3.07s?

Ill supply parts, beer, and just let you slap the carriers in without caring about proper gear pattern :ROFLMAO:
