These springs are a breeze compared to the set I made for the wagon. The simple built-in clips realy simpifly assembly. It's like I've been here before, with my pipe vise and wire wheel under the shade tree.

The rear on the broken originals had a leaf removed years ago, but the good donors had all 11 leafs. The fronts share a lot of leafs, including the main leaf and military wrap, with the MB, CJs, and wagons. Willys didn't change too much even between models. After prepping all the leaves they all get a coat of rust converter and rustoleum. Some folks would say it's a waste, but I figure that in addition to filling any pitting with paint to slow future corrosion, the paint also works with the lubricant as it gradually wears off. It's (painting each leaf and using the graphite paste) worked for me for years. I also got the frame painted with POR15.

This thing is a beast! I think it's close to a Dana 60 in how massive it is. It's certainly more massive than the Dana 53 that came with the donor truck. I cobbled up some supports to hold it while I figure out how to get it apart and check on the condition. I can't use my normal differential stands because it splits in half.

Hmmmmm, so that's why the parking brake never worked. The equalizer is missing from both sides. I see the shoes are separating from the metal backing too. Luckily I have a couple of "parts" Timkens. I'll probably have to buy new shoes, but I think I have all the other little doo-dads I'll need between the parts axles.

Well look at that! Glyptal! The wear pattern on the teeth looks good, as do the bearings, and it didn't seem to leak too much. The wheel bearings and seals seem good too. I'll look closer, but I may install all new seals and call it day. Even the axle tubes are clean and free of grease. This thing seems to be in great shape!

I removed the snap ring from the front pinion bearing, the bearing that's no longer available, and tried to pull the pinion out using the fine threads on the pinion nut. I pulled as hard as I dared, and then a little more and it wouldn't budge. After doing some research, including Vintage Dons thread
https://www.oldwillysforum.com/foru...ge-don-and-a-1948-willys-pickup.18442/page-20 I decided to leave it alone for now. I'll get all new seals, but installing new bearings where there's minimal, if any, visible wear, might be asking for trouble in this situation. We'll see after I do a little more cleaning and checking. The wheel bearings look good too. This is not a situation I usually find myself in. I usually replace all the bearings and seals and often the gears as well.

As far as re-assembly, I did note that the gasket maintains a dimension that could be critical, so I measured it; 0.004" thick. I posted that in case I lose my notes. This is a "simple" spirol bevel gear, not a hypoid gear, so some of the rules are different, and the manual basically indicates that if something isn't right, I'm screwed, so this is one of those situations where I might just re-seal it and go. It's in great shape and if I keep it clean and full of gear oil it should outlive me and the next caretaker.
