Purchased a new 500 box through Summit a few months ago to replace a 605 box in my 55. Have driven the car a few times now and when the car warms up, the steering gets tight in the center where the tires are straight. Like between 10 and 2 it’s tight. Makes cruising and making minor lane adjustments awkward. Has anybody had a similar issue. I thought it might be an issue with the pump, but after replacing the pump the issue is the same.
