has anybody converted from awd to 4wd. my tahoe is stock awd but uses a two speed case. meaning i have awd or 4lo. but the case is week so i went with a nv149 case. well its about shot now too so i'm ready to just go 14 bolt and push button 4wd. being that mine has push button setup already, would it just be a matter of swapping the buttons and the harness portion? also i have no need for auto track in the 243 case and i want to swap to a 4l80e, so would it just be better to run a hd push button case? i know i will need a new front diff or at least half of one. mine doesn't have the actuator on the side like 4wd trucks do.
