Is a Spindle Washer Needed Between the Spindle Nut and Outer Bearing on Dexter 5 on 4-1/2 Hubs

Question:

On a Dexter 5 on 4 1/2 Hub, should there be a washer between the axle nut and the outer bearing? On all other trailers and cars there is a washer, none on the Dexter trailer I have, just a large nut that covers the whole bearing.

Expert Reply:

Yes, there should be a washer of some type between the spindle nut and the bearing on your trailer. The washer protects the back side of the bearing from the edges and points on the back side of the spindle nut.

There are several types of spindle washers available depending on the spindle configuration on your trailer.

The Washer For 1 inch Spindle, # SW1000, is typically used on spindles that have a castle nut, like # 165686, and a cotter pin, # 165649.

A D washer, # 5-23, would be used on a spindle that has a flat side and uses the same castle nut and cotter pin setup.

A Tongue Washer, # 165863, would be used on a spindle with a groove cut through the threads, and would use the same castle nut and cotter pin setup.

A Tang Washer, # 5-101 or # 5-71, could be used with a spindle that has a D shape or a groove, and no cotter pin. The tang on this type of washer is bent up in one or places to prevent the spindle nut from turning and a cotter pin is not needed.

Before installing spindle washers on your trailer, you should check the outer bearing for damage. If you see grooves or scarring of the bearing, you should replace the outer bearing and remove and repack the grease, # L11380, in the trailer hub.

I have added a video on repacking bearings and a link to all of the wheel bearings we carry for you.
