n1gzd_plymouth Posted December 25, 2019 Report Share Posted December 25, 2019 My engine is rebuilt and back in the car. Car runs and drives. Main issue to resolve now is rear end leak (new after changing seals - worse with new seals). Rebecca Quote Link to comment Share on other sites More sharing options...

Rebecca Axles, pinion or all 3?nos oem seals should be soaked in oil before installing. some of those older axle housings had a couple seals on axles,and a grease fitting to fill the void between them. Gear lube should be 3/4” to 1” below fill port. also if it has a vent, make sure its not plugged.

I made the same mistake on a 1940 Dodge truck over 30 years ago, I didn't soak my seals in gear oil, and I put grease on them before I installed them. What a messy disaster!

Tooljunkie Posted December 25, 2019 Report Share Posted December 25, 2019 I just did my front wheel seals on the Fargo. Old stock leather. They soaked up oil instantly. They were thirsty. Quote Link to comment Share on other sites More sharing options...
Dartgame Posted December 25, 2019 Report Share Posted December 25, 2019 The old style seals can wear serious grooves in the axle shaft etc. Might be a good idea to examine and install speedy sleeves if they are bad... 1 Quote Link to comment Share on other sites More sharing options...
dpollo Posted December 28, 2019 Report Share Posted December 28, 2019 a speedi sleeve makes a nice repair but they are spendy. 1 Quote Link to comment Share on other sites More sharing options...

Lesson learned LOL diff housing seal. we think corrosion is preventing the new seal from sealing (old seal matched the corrosion). will revisit in spring.

Andydodge Posted January 27, 2020 Report Share Posted January 27, 2020 Personally I would never use leather seals even if they have been soaking for a year in oil............although if there is a groove worn in the axle or whatever the seal rides on then it won't matter what the seals made of it will leak anyway, so a speedie sleeve or similar is required......I'd chase up a neoprene seal but thats just me........andyd 1 Quote Link to comment Share on other sites More sharing options...

Rebecca I hope that your second attempt will be successful. I have used crocus cloth and 1200 Grit sandpaper to repair rusted shafts. But if there is one available, always try to find a speedy sleeve(seal saver) first. Let us know how things go Rebecca. Quote Link to comment Share on other sites More sharing options...

I have not driven the car with the new engine. Got it done just about then the salt and snow arrived. snug as a bug now. I did just notice an oil leak under the firewall on the left side. I have not investigated but I am wondering if it is leaking line from oil filter hosing. will investigate soon. Rebecca Quote Link to comment Share on other sites More sharing options...

n1gzd_plymouth Posted March 12, 2020 Author Report Share Posted March 12, 2020 other than repeated investigation I have been unable to figure out where this leak is coming from. I can see no oil above the cross member (on either side). Is dripping from the cross member (left side of car). Hopefully when I finally start it up for the spring I an see if it is a real leak (vs some oil that had pooled somewhere from before and is finally pouring out).
