09 Vibe GT FWD Won't Move

[BNAP]

Hi, I'm new to GenVibe, and need opinions.

I just replaced both CV axles on my 09 vibe, which went well, but now the car won't move forward or reverse. I bought the axles from NAPA, and though they were tough to get out, they went back in pretty easily. I lost a little fluid, and replaced it. My only thought that I'm not sure of, is that I removed both right and left axle at the same time, while NAPA got them in. It seems that maybe the axles aren't engaged in the differential for some reason???

I welcome any thoughts and/or opinions.
