Using 6000 lb Hubs on 7000 lb Axle
Updated 05/29/2012 | Published 05/25/2012
Question:
I would like to know if this hub will fit a 7000 lb axle Reliable that has the same specs as their 6000 lb axle legnth, tube size, OAL, both state they use the 1 3/4 inner bearing and 1 1/4 outer bearing. The reason I ask is I already have the 7000 lb axle but would rather use 6 on 5.5 wheels 15 instead of having to use 16inch as I plan to put 12inch disc brakes on the axle. I saw where you can put the 7000 lb hubs on the 5200 and 6000 axles so I figured the 6000 lb hubs should fit on the 7000lb axle. The 7000lb axle is #124442. The 6000lb axle is #124440. I do not plan to build a trailer capable of hauling 7000 lb but got a good deal on the axle. Thank you for any information you can give me Thank you for any information you can supply.

As long as bearings on the hub you choose are compatible with the existing spindle on your axle, you can indeed change to hubs that have the desired wheel bolt pattern. The first step would be to confirm the dimensions of your spindles using an accurate measuring device like a digital caliper. Using a ruler would not provide a measurement that is precise enough. I have provided a diagram that will will show you where to take the measurements. The # 8-213-5UC1 hub would be compatible with the bearing inside diameter you mentioned.
Remember, your axle weight rating will be determined by the capacity of its lowest rated component. Using a 6000 lb capacity hub on your 7000 lb axle will not be a problem, but doing so will lower the axle capacity.
The reason we do not recommend doing this is that although you will know the axle capacity has been lowered, in the event that you sell the trailer in the future, the lowered capacity will not be immediately evident to the new owner. Overloading the hubs can cause all sorts of evil things to happen, up to and including loss of the wheel while the trailer is in motion.
