Toyota Tercel

I have a 1993 toyota tercel with 91,000 miles on it. Yesterday I got the front brake pads and roters replaced. They said I need a new CV joint as well but I could wait a little bit.

So, while driving last night I noticed a humming sound coming from the passenger side. What could that sound be? Is it normal after getting new roters on a car?

Maybe it needs time to break in or its time for the CV joint replacement.

Hope this help-Good Luck
