Do Mobile Home Axles Have Weight Capacity Rating  

Question:

I just got a pair of old axles off of a 50s model mobile home frame. They are 6 lug, axles, electric brakes and tubing is 2.5inch wide. No identifying numbers on them, and they are extremely heavy. Any info on the load rating would help, is there a way to tell by measuring spindle and bearing sizes perhaps. Any help please..

Expert Reply:

Mobile home axles are designed for a one time use and do not have a load rating. You may be able to find hubs and drums and other hub components for the specific spindles you have on the axles but that can be very difficult as mobile home axles typically have non-standard sizes.

I have attached a drawing that shows where you would need to measure on your spindle for the replacement components. You will want to measure the spindle in the places where the bearing ride and also the inside diameter of the hub. You will want to use a digital caliper like part # PTW80157 to get these measurements.

t might actually be more cost effective to replace the axles with some that come with hubs and drums and electric brakes. That way you get all new parts that are all standard and compatible with each other.

My brother used mobile home ax!es on his 16 ft. Trailer for many years. Low Boy tires. He used aLittle longer bolts to attach the wheels. Jacked trailer up a little to be able to spin tire with a guide toMake sure it was centered. Then on the bolts put a heavy duty lock washer and then torqued all bolts to 90 lbs of torque. Never had an issue.

There are plenty of mobile home axles and hubs on the road, but it's still not something that we recommend for routine use - they just aren't designed and built for that type of application. Prolonged use likely requires modifications like on your brother's trailer and replacement parts are really hard (if not impossible) to source when the time comes.
