Expert Reply:

It appears you need a spindle nut. We have a couple of options for you to work with your 2,500 lbs axle:

The Trailer Spindle Nut 1", part, # 165686 and the Washer For 1", part # SW1000
Replacement Trailer Spindle Jam Nut, part # 6-191 and the Replacement Nut Retainer for 6-191 Jam Nut, part # 6-190

They each have 14 threads per inch and work with axles with 1" spindles. Each spindle nut needs either a washer or a nut retainer. If your spindle uses a cotter pin, you will need the first option.

I have included product description links and video review links below.

Yes, spindle washers are to be used except in a rare occasion where they will not fit. However, the Dexter Trailer Axle with Idler Hubs #20440I-ST-72 does not come with washer. You will need part #SW1000.

Answer 6

The two bearings you mentioned have different inner diameters. The #L44643 has an inner diameter that is exactly 1 inch and the #L44649 is 1.06 inch. This may not seem like a lot but it's a big enough difference to prevent the hub you have now…

Answer 7

The best way to select a new hub is to match it based on the bearing set used in the original part. New hubs must use the same bearings as your old ones in order for them to fit on your spindles, so if you can find the part numbers from your inner…
