Jul 21st, 2025 | | | | Joined: Sep 2008 Posts: 53 Wrench Fetcher | | Wrench Fetcher Joined: Sep 2008 Posts: 53 | I have a 1952 3600 3/4 ton truck, and i have oil leaking from the differential pinion seal. Does any one know where i can get one of these seals? I shall also be re-newing the grease seals on the hubs. But looking thru the 'classic parts' catalog i can't seem to find the diff seal. Can anyone help please. I live in the UK and could do with a little help with this one please.
Thanks

have you got the pinion nut off? if not, have fun. if you do, you can use a micrometer to measure the od and id. that will help the auto store folks get you a seal that will work.
there is also a piece of felt rope stuffed in front of the seal. mine was in good shape and did not need replacing but if your's needs to be replaced that was a part i could not find. you might be able to use water pump packing.
a speedy sleeve may be needed as well if the pinion shaft has been worn by the old seal. | | | | | Joined: Sep 2008 Posts: 53 Wrench Fetcher | | Wrench Fetcher Joined: Sep 2008 Posts: 53 | wrenchbender, that would be great if you could see if they would send to the uk.

Tim | | | | | Joined: Jun 2004 Posts: 8,597 Riding in the Passing Lane | | Riding in the Passing Lane Joined: Jun 2004 Posts: 8,597 | The part number for the pinion seal is 411330N. The felt is 5M88. The sleeve is 99259. The wheel seals are #2081. These are the National brand. The pinion seal was used on most 3/4-1 tons up to 1972. The wheel seals were used clear up into the 90's. Did you check a local parts store? It seems there would be a lot of Chevy trucks in that area. Our parts stores have parts for europe & asian vehicles. The sleeve is expensive for what it is but cheap for what it does. Let us know if you can't & i'll see what it takes to send them. George

It provides a new surface for the seal. NAPA has these parts and I think CarQuest has them as a set. | | | | | Joined: Sep 2008 Posts: 53 Wrench Fetcher | | Wrench Fetcher Joined: Sep 2008 Posts: 53 | Thanks guys. I will see what i can find over here, and if i have no luck i will be in touch. Chevy dealers in the uk are very few.
