I searched and cannot find anything on this. Probably because I'm the only one inexperienced enough to ask. My 09 4x4 Silverado needs the rear end rebuilt. I know better than to diy it so I want to have it professionally done. My question is, it has 3.73 ratio and I have a 3.08 with the same exact features as my 3.73. Active brake, posi, stabiltrac, all the rpo codes match except the ratio. I'm pretty sure I can't put it in there permanently and run 2 different ratios. My question is, since it takes weeks or months to get the rebuild done, can I put the 3.08 in there so I still have something to drive, as long as I don't engage the 4x4? Thanks in advance.
