I have a 2000 toyota solara and when I'm driving it tends to have a grinding noise when the pedal is down but when I let go it stops sometimes at first it was doing it every now and then but it's doing it more often now, originally it was close to the wheel making me and everyone else I talked to think it's a wheel bearing but now it's moved closer to the transmission, and when I have someone look at it they can't hear anything, I need help soon because now I'm thinking it's more of a CV axle and it's pulling to right after having an alignment done, I don't want something that dangerous to break while I'm driving and end up in a ditch or another car Mechanic's Assistant: Have you heard this particular sound before? Yes and it started a couple months ago and got worse but no one basically will help me until it breaks Mechanic's Assistant: Are you fixing your Solara yourself? What have you tried so far? I haven't touched it but I don't know what is causing it to even fix it Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? That's all
