Question:
Does the TRU57FR come with a standard washer and cotter pin? I see that other spindles come with the D washer and tang washer. Why are there 2 styles of retaining the nut? Thanks,

Helpful Expert Reply:
The #42 Spindle # TRU57FR does come with a Standard Washer # SW1000, Cotter Pin # 165649, and Castle Nut # 165686 to secure the hub to the spindle.
The D-Washer # 5-23 and Tang Washer # 5-101 were created to allow for a Grease Zerk # LC44XV to fit the end of the spindle and allow you to grease the hub bearings without removing the hub. There are some versions using a grease zerk and cotter pin but those are more likely to not allow grease to reach the bearings as it can come out the cotter pin hole.
