I'm already replacing the 74's. I am inquiring about the 67's. I figured it would not be such an easy repair. I've had this mower for numerous years now, and never changed any of these bushings. There's a lot of play in the steering, and I have a toe out situation, too. I have new steering linkage, new spindle bushings, and I replaced the front tires. So, it's a difficult repair?
