OK, here is what I see...the passenger side axle connects to the extension shaft right at the bracket. The bracket has 2 bolts holding it to the engine block. These 2 bolts (most brackets on other cars have 3 I think) are very difficult to get to as there is a lot of stuff in the way. Also at the bracket, it looks like the axle joins the extension shaft but is covered by some type of coupling that has 2 bolts, one at the bottom and one on top of the shaft. I can feel the one on the top, but can't really see it.
Question, do I take out the entire shaft assembly by removing the bracket bolts (somehow) and then separate the axle from the extension shaft, or do I take off the coupling and separate the axle from the extension shaft leaving the extension shaft in position inserted into the transmission? Or maybe if I remove the coupling, the entire shaft pulls out of the transmission? All the videos I have watched seem to indicate the whole shaft needs to come out, then separate the axle from the extension shaft while off the car. Thanks for all the help.
