What Size Spindle is Needed for a M/H trailer

Question:

How do I know which spindle to order for this type trailer? It is a 5ft. X 12ft. trailer and I would say light weight. I bought it used and do not have any info. in regards to size axle or spindle. Please reply ASAP. Thanks, James

The axle spindle you need to order will depend on the weight capacity of your trailer and on the type of spindle (see link) already being used, if you only need to replace one spindle.

To figure out which spindle is correct you can use the bearing part numbers, both inner and outer, and the shape and length of the spindle stub on your trailer. The bearing numbers will let you cross reference the correct spindle measurements for your hub. The axle stub shape and length will allow you to use the same mounting position as the original spindle.

Your trailer weight capacity can usually be found on a tag near the tongue of the trailer or stamped into the coupler itself.

If you need to replace both spindles, bearings, races, seals and hubs you can use any spindle of similar construction that is rated heavy enough for the trailers capacity and purchase the correct hub assembly (see link) to go with the spindles. Be sure to order the correct bolt pattern for your trailers wheel and tire combination.
