A step by step video showing how I diagnosed, removed and partially tore down a damaged GM 246 (NP246) transfer case on a Chev 2000 Suburban 4X4 with the 4L60-E automatic transmission. The video shows details of removal and installation of the case, though full rebuild details are not shown.


For the best 246D disassembly I've ever seen, don't forget to watch this one:

If you decide to inspect your vehicle while in drive with rear wheels spinning, be wary for your personal safety, since sudden loss of life or limb may be only inches away.
