Camry99 It could be. The problem is I can't hear or feel what you tell me.
You've mentioned a grinding noise, a weee sound, and a squeak. The squeak could be a suspension part like the strut or shock. The grind and weee sound could be a brake caliper piston thats not releasing completely and the brake pad is grinding on the rotor. It could also be a warped rotor. I could go on and on with "it could be".
You really need someone there who can analyze the situation hands on. Good luck.
