How to Determine Replacement Hub for M416 Military Trailer
Updated 04/02/2018 | Published 03/31/2018
Question:
Hi, I would like to convert my 1966 Johnson M416 military trailer to 8 lug x 6.5 and retain the E-Brake. Do you have any hubs that would bolt on that would achieve this? Thanks,

Due to the age of the trailer, we will want a little more information to make sure we get you the correct hub and drum assembly and brake assemblies. The best way to choose a replacement hub is by using the bearing and grease seal part numbers that are stamped into the metal cage of the bearing and the rubber of the seal. With these part numbers, I can cross reference the correct hub. We've had a few people ask for similar hub replacements for your M416 trailer and we've given them this and the following info and we've yet to hear back if there is a solution that we offer.
If you cannot determine the part numbers of the bearings or seals, then the next best option is to measure the bearing and seal journals on the spindle. You will want to use a precise measuring tool such as a dial caliper because the measurements must be accurate down to the thousandth of an inch. With these measurements, I can determine what bearings your spindle requires. I have attached a photo that shows the part numbers and where to measure on the spindle.
If you want to add electric brakes, then you will want to make sure your axle has a brake mounting flange welded to the axle. The brake mounting flange is typically welded right behind the spindle and has 4 or 5 bolt holes to mount a brake assembly. Can you tell me if you have a brake mounting flange and how many bolt holes it has?
With this information, I can see if we have hubs and brakes that will work for you.
