Question:
Hello, I'm trying to determine the size drum/hub I have on my Jayco 195RB baja travel trailer. It has a 3500 lb axle and is a 5 lug on 4.5inch bolt pattern. The inside measured diameter is 10 inches and the width of the functional part of the drum is about 2 3/8 inch and the overall inside width is 2.5. All the 10 inch drum/hubs I see on E trailer are either 2 1/4 or 2 5/8 wide so I'm not sure what parts I need?

Expert Reply:
Tape measures are not as accurate a measuring tool as a digital caliper like Item # PTW80157. Based on your information, we know it will be a 10 x 2-1/4 inch hub. Another great way to find the right size is to match your inner and outer bearings which have their sizes stamped on them. It sounds like you will need 10 inch hub and drum like Item # AKHD-545-35-K that fits 3,500-lb axles with an inner bearing like Item # L68149 and and outer bearing like Item # L44649. Make sure to check your bearing numbers to confirm correct fit.
I have attached additional information and some videos that will help you with your project.
