CV axle replacement

I recently changed the r CV axles on both sides and after about a week I noticed some play and a wobble on my driver side. Took off the wheel and it looks like the axle where it goes into the transmission is bout a inch to inch and a half from sitting completely into it. Do I need to take it off and redo it? And it's now leaking transmission fluid. Also same car I had my power steering pump replaced and they broke the power steering switch in half while doing it not telling me. I noticed a leak coming from it and replaced it and the harness because the way it broke the old one wont come out of the harness. It's still leaking and still whining what can I look at or do? Can I just tap it back in with a hammer? And is this where the oil seal is at or is it where the oil filter is at? My manual is confusing on all this as it doesn't show a lot of detail.
