I mostly notice this crunching sound when I first accelerate the car the first time of the day and also when I turn right. Sometimes it sounds like it's coming from the front passenger tire/side when I turn right. But when I am first accelerating, it sounds like it's coming from the acceleration. I've taken it to Toyota twice and of course it doesn't do it then because I've been driving. Also it doesn't seem to do it at faster speeds once the car is going. It's driving me crazy. I don't want to wait until something major happens. Any thoughts very much appreciated.
