My Impreza has a vibration in the steering wheel around 65+ mph. I had the tires replaced, road force balanced, and new rotors put on. Shake eased up, but is still noticeable and a pain on long drives. I also just had an alignment, but it seems to have gone right back out of alignment after a couple weeks. Car has about 75,000 miles on it.
Any ideas on how to remedy this? I’ve already dumped a good chunk of change trying to get this taken care of and would prefer not dumping a ton more money into it.
