Looking at the frame diagrams in the parts lookup, I see that the QL series frames uses a front and rear pivot pin bushing (items #20 & 21, part #'s 711-3005 & IH-384837-R1) for the front axle pivot pin, whereas the 1x8/1x9 frame does not have these bushings, yet the pivot pin is the same for all (IH-384626-R4), and the axle beam is the same for both series (part # 759-3270).
Are the pivot pin bushings for the QL series frames replaceable?
If so, how do you remove/install them?
Thanks
