  • Driver Drop Diff Flip

    In doing a spring over why would a driver drop diff not work if flipped to do a passenger drop spring over?

    I'll just keep it simple and say it doesn't work like that.

      That would also make it a high pinion.

        Well, the big issue would be that once you put it in 4wd, the tires would try to turn the wrong direction. By just flipping the axle, you move the ring gear to the opposite side of the pinion which makes the tires rotate the opposite direction, given the same input rotation.

        Then there are the other issues like the caster angle being way off, the ball joints would be up-side-down, and while flipping it would raise the pinion(not to be mistaken for "high-pinion"), there would be oiling issues.

          And leaks from the vent fitting, and we already have enough of those

            And steering problems. When I was a kid I tried that with one of my first cars. A '66 Chevy Nova. It had the monoleaf and sagged bad in the back so we flipped the axle and I had 2 speeds reverse and one forwards! (194 6 cyl with Powerglide) We even drove it on the highway like that, ala "Hooper" after adjusting the steering.

              Plays hob with the caster and camber too.

                Plus you'd be driving on the concave side of the ring gear teeth, which is the weaker side.

                  So,,,flip it. remove the knuckles and weld them onto the other side, right side up, change the gears to reverse cut gears like the newer high pinion 44s' have....now what?

                    While they gave you lots of reasons I think it wasn't a bad question. It does seem like an 'easy' solution at face value but unfortunatly it just doesn't work.

                      Reverse cut gears still rotate in the same direction as gears in a standard axle. the teeth are just cut "reversed" because in a HP axle, the pinion comes in above the ring gear center line.

                        Will still have lubrication issues as well. Pinion bearings won't live long. The high pinions are designed to eliminate the lubrication issue.
