I believe that my front axles are slipping and need to be replaced, but I am not sure if I am correct or not.

At acceleration, I will feel what seems to be a slipping or weird misfire. It is prevalent when I WOT from a dead stop, and WOT on turns. You can feel it on the floor which makes me think that it is not a misfire. It does not happen every time, and it is now happening on both side. Before, it was only on one side.

Is there anyway to diagnose this axle issue without tearing the car apart first? I MIGHT need a new FPR too, but I am going to try and diagnose that today. Any help or suggestions is appreciated. Thanks.

Axles don't slip, transmissions do. A bad axle (CV joint) will manifest itself as continuous clicking/clunking when moving with the wheel turned.

Check your transmission fluid colour/smell/levels (engine/trans warm, engine running), and engine mounts. How does everything feel during shifting?

Transmission is fine. Shifts perfect. Fluid is good, and I had the transmission rebuilt about 20,000 miles ago. There is a very tiny rip in the passenger side CV boot and it is not throwing any grease, but it did let out a small amount sometime ago.
