I just posted about this earlier today. If you have some fibre type wheel bearing grease---which was usually short fiber but could have been long fiber (or any good thick fibre grease) hand pack those well, put them back together and install new grease seals. The thick fibre (or fiber if you prefer) grease will stay in place a long time (won't squish out like the junk we get today), will take up slack and does a nice job of cushioning mechanisms like the shackle pins, ball-bearing type wheel bearings, steering rod balls & cups...any sort of stuff like that. This grease was used widely for big trailer connections. This grease is no longer made but all grease is just oil that's been treated with an agent...thickening agent which is called a soap and that could include light metals as well. There are not fibers in this grease but it looks like there are. The soap causes the grease to separate into strings. Anytime I see any for sale I buy it if the price is right. Attached are two images. One shows the stuff and you can see the fibers in it. One shows the can. 30 years ago this was about $2 a pound. Not the same today but if you own one of these trucks, you may find this very useful. Good luck.
