I'll have the rear knuckle bushing checked. I don't think it's my strut or strut mount since I changed both of them when I changed my struts (Tokico Blues), I got one of those strut mount kits. I don't think it's the strut since it's still only happenning on the right side. It would be a big coincidence if my Tokico strut is bad on the same side it's been making the noise. If I go over a bump with just the left side of the car there's no noise. I'm taking my car to the dealership during lunch and the head tech said I could drive him around and he'll check it out to see what it is.
