I just bought this 2000 scrambler and I have a question about the steering stem. I can move the steering stem up and down by pulling up on the handle bars. From what I can see there is a bushing on the bottom of the steering stem that has a nut on the bottom of it that is probably worn out. I have been looking and cant find this part anywhere to purchase the new bushing. Has anyone replaced this and were did you get the bushing from ? Thanks
