I went to replace the rear wheels cylinders in this truck that has been sitting 40 years. When removing the hub/drum, the outer seal was shot and there is no inner wheel bearing seal on either side of the truck. I have tried finding seals that fit this truck's description, but no luck. I purchased one from Jim Carter's for a 1 1/2 ton b/c the 1 ton was too small (3 15/16) and the dimensions appeared very close, but was 4 5/8 inches bore versus the 4.5 inches that I have. The inner seal shoulder/shaft is 3.188 with the hub measuring 4.5 inches. There is possibly a seal on the axle housing that has a metal facing w/ a felt backing a little over 1/2 inch thick and measures 4.40 inches in diameter. So this is 0.05 gap between this "seal" and the hub. My brakes were soaked on one side from brake fluid and maybe grease but definitely had grease throughout the drum on the other side where my wheel cylinders did not leak. Also my wheel bearing grease was washed out.
Did these trucks come with a wb seal and the last guy just didn't put them in or did this model use these metal-backed felt seals? I'm afraid my new shoes will be grease soaked in no time.
By the way, the felt ones are inward on the axle housing with the 3.188 inch shoulder described earlier in between it and the bearing and the shoulder is about 1/4 inch deep.
Also, can someone confirm this is a one ton and not a ton and a half...I have been told both but have not had much luck searching the internet for confirmation?
Thanks,
Hilarious
