I'm just about ready to do the supersteer upgrade on my 1711. I have a front axle and all the connections necessary from an 1863 that I am using for this upgrade. The spindles are a little loose in the front axle. When I look at SUPERSTEER in Charlie's FAQs, it talks about replaceable bushings for the spindles and center pivot. Are there bushings that can be knocked out and replaced or does the axle need to be bored out and bushings inserted? I would appreciate all the help I can get on this.
