Is the Grease Seal Seat Larger Than the Bar Stock on the Square #84 Spindle TRU47FR

Published 11/08/2022

Question:

Your dimensional drawing for spindle Item# TRU47FR shows the square section of the part to be 1.5. However, the smaller diameter of the adjacent mating surface for the grease seal is 1.73. So, Im assuming that the square portion of the axle is actually 1.75, Is this correct?

I checked with the manufacturer, TruRyde, about the Square #84 Spindle (1750 lb) part # TRU47FR and can confirm that the grease seal portion of the spindle is actually larger than the bar stock. The grease seal mating surface is 1.73" and the bar stock that gets welded inside the axle is 1.50". It's hard to tell in the photos but you can just barely see the grease seal mating surface sticking out from the bar stock.
