Question:

How do I know if this will fit my trailer? I have a 2006 Karavan, the bolt pattern is right, 5 X 41/2 but will it fit my spindles?

The best way to determine which replacement hubs you need for your trailer would be to remove one of the hubs and retrieve the bearings. Find the numbers stamped into the bearings and with those we will be able to get you the correct hubs.

If you are unable to retrieve the bearing numbers, you can take measurements of the spindle. I have included a link to our spindle main page. At the top of the page is a diagram showing all of the measurements we would need to find the correct hubs and bearings. The measurements need to be as precise as possible so I recommend using dial or digital calipers if you need to measure the spindle.

The Trailer Hub Assembly, # 34822545BX, uses # L44643 inner and outer bearings. It will fit on several spindles including # TRU94FR, # TRU44FR, # TRU97FR, and # TRU59FR.
