Re: Help.. gearing stupidity

As much as I like to drive the streets. 4.10 is as low as I would go for a truck with 33/35 and a trany with a 1:1 3rd. If it will never see the free way or Hwy 4.88 would be cool to have. If you have the money you can put a 4 speed over drive in it and go low with no prob.

Special tooling yes and a lot of patience getting the bearing preload and backlash correct.

Re: Help.. gearing stupidity

Press, setup bearings (make them yourself), dial indicator, accurate 1/2" torque wrench, seal driver, locktite...That should cover 95% of it.

Maybe a pinion depth tool and a case spreader...
