Hopefully you don’t need to replace the hub. You should be able to replace the inner and outer bearing sets and be as good as new, unless the bearings are too far gone and have spun the races in the hub.
Hub and drum appears to be one unit

You can still get them. If i had to take one off though, I'd replace it with newer. It'll take the same bearings, just put a hub pilot hub, or you could do Budd if needed, and standard drum. Same brakes
Rideandrepair and blairandgretchen Thank this. -
Reason for doing this is i have replaced everything. Springs. Shocks. Tie rods. Etc. went through multiple tires and multiple alignments nothing changes it. theres still a very intense vibrations on front driver side between 65 and 75. Its so intense that sometimes its like the front left side is hoping dwn the road. The only real relief is when im loaded. It still does it but not nearly as intense. Any help?

IMO, a dyno is very effective in isolating hard to find vibrations

The drum will bolt to the hub from the inside face. You pull axle then bearings and slide them out as a unit.
Diesel Dave Thanks this. -
We had a problem like that in a large fleet once. A truck was transferred in with that problem. Even took the hub off and took it to a machine shop. They said it was true. Our tools to test with were fairly crude but we kept coming back to this assembly. Swapped one off an older unit for sale. Problem solved but somebody bought a problem.
It could just be your brake drum.Rideandrepair Thanks this. -
If it were mine, I’d be replacing everything on both sides, so you have balanced performance and will be starting fresh. This includes kingpins, any bushings, drag link, tie rod ends, shocks, tighten the steering box slack, spin balance the steers, and anything else that could’ve been beaten to death by the oscillations. By your pictures, nothing looks very recent.
That shock is blown out and doesn’t look remotely new.
Likewise, this tie rod end hasn’t been touched in a very LONG time. That’s awfully crusty.
Rideandrepair and BoxCarKidd Thank this.
