Car has 260,000 miles. I have a steering wheel shake that has been occurring at random speeds. I first noticed it only at 60 mph and now it is occurring at 20 mph and 60 mph. I have also noticed the shaking sometimes reduces or stops when I turn the wheel slightly or am going around a corner. The struts, stabilizer bar and outer tie rods have been replaced. I have had a recent alignment and wheel balancing (road force). I’ve described it to my mechanic and he thinks it is the tires. I’m not so sure, but I had the balancing check two more times. Still no change. I’m suspicious of CV joints. I occasionally hear some clicks while turning, but it is quite faint.
