As you can see, there are two rear sub mounts. The kit comes with everything except for the center bolt, which the Baylor site says to replace. Get this at your dealer. There is one rear diff mount...at least the one that looks like this: click here
. It's under transmission. Remember when you replace it, replace the nut strip (2) inside the frame rail as stated on the Baylor write up. Also get those at your dealer. In the manual it discusses a differential bushing which almost looks like a half spherical looking thing...can't find it on FastLane, and I am not sure if this is a replacement item. Maybe someone else knows. I also want to know why the front sub mounts are hardly ever mentioned....they don't have them in FastLane as far as I know. Anyone?
