Today I pulled the hub/drum for cleaning, repacking, replacing the messed up stud and rebuilding the wheel cylinder.
The drum came off easily and the hub was pretty easy too. I took them in the shop and cleaned the old grease out of the hub. There was some chrome specs in the grease. I’m not sure if that came from the cage or the bearing itself – the turned freely and looked pretty good.
I repacked the bearings and hub then reinstalled on the Jeep. The wheel cylinder was a little more difficult. The cups were stuck and corroded in the cylinder and had to be driven out.
After honing the cylinder and installing new seals and spring, I inserted the caps. One of them was really tight, so I sanded and smoothed it until it moved a little better. I reinstalled the outer seals and bolted it back in the Jeep. Hopefully it will work fine – if not, I will be going through all this again.
The next job was to get started on rebuilding the front springs. I jacked it up and put jack stands under the frame right behind the spring, then jacked up the axle a little to take the pressure off the spring. I removed the lower shock nut, then the u bolt nuts (that required aero kroil and heat). The front pivot bolt was next – easy enough. The rear shackle nut required Kroil and heat also. Once removed from the Jeep, I took the spring pack to the shop, installed a c clamp to hold it together and removed the center bolt. Then I removed the bolts from the clamps. Lastly, I released the c clamp and separated the spring leaves.
You can see the broken top leaf.
I used a wire brush and a welding pick hammer to clean the leaves and remove the flaking rust.
This is how much rust I removed:
Next, I cleaned the leaves with paint thinner.
Lastly, I brushed on 2 coats of rust converter as the primer before reassembly. Lookin MUCH better! The new top leaf is in front – I cleaned and painted it a few months back when I received them (I bought 2 because BOTH of my front top leaves are broken!
I will have to buy new hardware to put the spring pack back together because it was all rusted pretty bad. Grade 8 center bolt 5/16″ x 2 5/8″ and grade 5 clamp bolts 5/16″ x 2 3/8″. I will buy 5/16″ ID tubing and cut my own spacers.
