This was the second year of driving the TR3, about 3000 miles and it took a real beating to get the spinners off. First year I only did around 500 miles and they came right off. I used a 5LB dead blow hammer to get them off using both hands. The rears wheels were not as bad as the front. No way I could get them off with the tires off the ground with the brakes on. I even heated the front spinners with a heat gun. I used a liberal coating of Valvoline high temp bearing grease on the hubs. Should I try a different grease or more off it? I've read you should tighten the spinners every 300 miles or so, no need on my car. Any Ideas?
