How to Determine the Right Size Bearing Buddy for a Ranger Utility Trailer

Updated 03/30/2015 | Published 03/27/2015

Question:

I have a Ranger utility trailer. I have measured the dust cap and it is 1.9725 The closest I can come up with is the 1968 I suppose the dust cap might compress slightly when ed. I wonder if the 1968 will work? Thanks.

Instead of measuring the dust cap you have, measure the hub bore where the dust cap fits. You need the most accurate measurement possible so using dial or digital calipers is the way to go. Usually the dust cap or bearing protector outer diameter is slightly larger than the hub bore. this is so you have a very tight fit.

It sounds like you might actually need a 1.98 inch, which is more common. But measuring the hub bore should tell us. In the event that the hub bore returns a similar measurement then the definitive way to determine if there are bearing protectors that fit is to go by the outer bearing number, which you should be able to see without removing the hub.
