I just had new tie rod assemblies on both sides installed,new brake caster bushings installed, had the wheels balanced and the front end aligned and the steering adjusted and I still have some steering shake at 75 MPH and 80 MPH. The car has 16 inch 8 hole Mercedes late model S class wheels. Anyone have an idea where to look?

Thanks

check your tires, ...most of the time, ..there's some defects such as bulging or sort that is hard to notice. Also, ..make sure that tire pressures are within specs.
If your tires are defective, ..you'll experience wiggling at high speeds..
