it si one of those things that i see a lot on different sites. people think the problem with the 7.5inch rear is the carrier or the gears. fact is that the case was designed to be functional and reduce materials useage. that is why GM went from 8.5inch rears to 7.5inch.
that left a case that didn't ahve all teh material need abover the bearings to hold the carrier correctly when power is applied. this can be solved to a large degree by welding the tubes to the center section(GM presses them in and then puts 2 tiny tack welds on each tube) and using a cover that has cap supports built into it.
