I just got my right front cv axle, my power steering fluid, and an alignment done. Next day I was turning left with speed and I hear a very loud humming sound. No obvious vibration per say. This only happens turning left at higher speeds, not going slow. I plan on talking to my mechanic on Tuesday about it but I don't want them to try charging me additionally unless its necessary. Any ideas? 2000 dodge neon at 95k miles.

 

It could be a wheel bearing.

Unless it gets loud all the time, it most likely could wait a while.
