    Just a quick question.....

    Can the factory 10 bolt front with 3.08 be converted to 4.56 without major surgery. Or, does it need a new carrier or will I need to get a D44 or D60. I will eventually swap in a D60 but until then, I want to use 4 wheel drive and my rear is about to be 4.56. So, if the conversion to 4.56 is simiply a new R&P then I'll do it, but if not, then I'll just live without 4 wheel drive.

  2. I think I've read that the cut off point to swap carriers is 4.11, I'm not sure though. Someone else can tell you for sure.

    Thanks Dan...

    Did yours come as 4.56 or did you upgrade from a lower ratio, maybe a 3.08?

    you can get 4.56's for a to bolt. I've check into it cause that's what I'm doing to the front.

    Don't hit me, Mr. Moderator... I'll go back on topic... I swear![​IMG]

    The carrier's are the same for 2.73 and numerically higher all the way to 5.57 and anything higher, if it exists. All you'd need is the R&amp;P.
