In order to replace your axle you will need to know your current axle capacity. In addition to the axle capacity you will also need to know the hub face to hub face measurement to match your current axle. Once you have this information you will be able to find a replacement, assuming one is available. Since you have square axles now and would be switching to a round axle you would also need new U-bolts.

If you cannot find an axle with the same length and capacity the other option is to use the Timbren Axle-Less Trailer Suspension System like the # ASR1THDS01 (2,200 lb) or # ASR3500S05 (3,500 lb). This system replaces your axle as well as your suspension.

In order to switch to electric brakes you will need new brake assemblies like the # AKEBRK-35-SA. You will want the brakes to match the drum size you have now. These brakes fit a 10" x 2-1/4" drum and are designed for 3,500 lb axles. You will also want a breakaway like the # 20400 and a brake controller like the # RED44FR for your vehicle.

I have attached some review videos along with links to our axles and brakes. I also attached a helpful article on adding electric drum brakes for your reference.

Answer 5

To determine the size of the brake assemblies you need you have to measure the depth and width of the hub drum on the axle like what you see in the picture I attached. The most common size is 2-1/4 inch wide like the #T4071600-500 that you…

The Timbren Axle-Less Trailer Suspension #ASR2KHDS09 you're looking at is actually not going to work with your trailer tires since this kit is only going to work with trailer wheels that are 16" or larger. So, instead I'd recommend going…

All you need for attaching a brake controller to your 2022 Hyundai Palisade is the receiving-end setup. For that setup, you need to have a 4-way and a 7-way wiring harness in order to use a brake controller. If you do not have the 4-way installed…

The Timbren Silent Ride #TSR14KT01 can actually be installed by welding it on or bolting it on. You could do both welding and bolt it on, but that is not really necessary. I am not sure of the bracket to move it around on the frame, but they do have…

Answer 11

While we don't carry that specific part number essentially it is just a 3,500 lb trailer axle hub/drum that has a 6 on 5-1/2 inch bolt pattern like the Dexter #84656UC3-EZ so this would work perfectly for you.
