Went to look at the other side for reference, it was missing the spring-clip and washer too! It has to have been like that when I bought it, unsure how the 4x4 actually worked last winter. The driver side seems like it would naturally stay in about the right position. But, the passenger side must have been stuck in place by sheer time and old grease.
Our best junkyard only had 3 1st gens left, all had these parts already gone. I felt like I needed to get this fixed immediately with the axle just flopping around in the spindle, so I hit the dealership, and they hit me back harder. Clip is $8, washer/spacer is now $18. Times 2 sides and tax, and I'm out at $57.
I'm going to buy spares now off the internet. I found the clip for $2, have not found the spacer/washer yet.
Getting them on was a surprising fight. Both sides would not give me enough axle to fit the clip... close, like maybe 1/16". Additional prying and cursing and they are on.
Discovered bad lower ball joints, both sides.
