I looked up some specs on your 2005 Karavan BW-2350-74-ST and based on its GVWR it more than likely uses a 3,500lb axle, though I HIGHLY recommend verifying this first since trailer manufacturers like to just use random axles they have laying around.

Assuming it is in fact a 3,500lb axle you'll need bearing kit # BK2-100, but you can confirm this by checking the axle tag on the center of the axle beam to see what the axle rating is, or if the tag is missing which is likely due to the trailers age you'll want to use calipers # PTW80157 to measure your spindle using the below diagram.

As long as your outer bearing surface of the spindle measures 1.063", and the inner bearing surface measures # 1.378" the above kit will work perfectly. If you find you have a different size spindle just send me those measurements and I'll get you the right bearings.
