Are D-Washers and Tang Washers Both Necessary on Trailer Spindle

Question:

I have a 1998 tent trailer with dexter ez lube axle. It had a tang washer installed between bearing and castle nut. I do not recall another washer next to the bearing, The kits i ordered included tang washers, D washers, and cotter pins. The is no provision for cotter pins on the spindles.. Using the tang washer behind the castle nut do i also need the D washer next to the bearing. Instructions have been confusing. Thanks

Whatever bearing kit you got likely came with both to give you options. Since you already had a tang washer on your spindle you can stick with the tang washer. Using the tang washer like the # 5-101 with a D washer like the # 5-23 would give you no advantage.
