Determining Parts Needed To Convert Trailer From Hydraulic Brakes To Electric Brakes
Question:
the outer bearing is a L44649 and the inner is a LM48548 the tire size is 7 - 14 If I can convert just the hydraulic brakes to electric and not change hubs and rims I am okay with that. If we need to change everything that's fine too... can you give me a price both ways please. Thank you

I would be happy to recommend the parts you will need to convert your trailer from hydraulic brakes with 14" wheels to electric trailer brakes with new 5 lug wheels, but first we will need to determine a few things about the trailer.
First you will need to find out which inner and outer hub bearings your trailer uses.
There is two ways to accomplish this, with the easiest being pulling on hub off and checking for the bearing number on each bearing. This number is stamped on the face of the bearing as you can see in the included picture of the # L44649.
If the bearings numbers are not readable, you will need to use digital calipers like # PTW80157 to measure the spindles according to the included diagram.
With bearing numbers or spindle measurements I will be able to recommend the correct parts that will fit your trailers axle.
Lastly if you can provide the tire size of your current 14" tires, I will be able to make a recommendation on new wheels and tires. It is important to keep the tire size close to the same size to avoid any clearance issues cause by the tire being too wide and hitting the trailers frame, or too tall and hitting the wheel well.
I included a helpful article on adding electric trailer brakes to a trailer for you to take a look at, and once you send over the bearing and tire information I would be happy to recommend all of the correct parts to complete the conversion.
