Try driving Very slowly in a parking lot and having a friend watch your front wheels/tires. My mechanic was able to show me and I could clearly see that the wheels/tires seemed to not rotate smoothly. I could see that the rotation looked jerky and not smooth. You can't see this yourself from the driver seat and at speed you will not see it either. Once the buhsings were removed I could also see they had failed. I went with Meyle over Powerflex. Very happy so far
I am not 100% certain the parking lot observation will work for you but it did in my case. It's worth a try.
