My job purchased a used 3226 skyjack, after purchasing it I started to go through everything on the lift and noticed the white slider bushings are shot. Can anyone tell me how to replace these bushings. Seems like the entire scissor stack needs to be removed for them to be replaced. I really hope not, I can't find anything online that points me in the right direction. Thank you
