Green Mesa XJ Posted March 27, 2017 Share Posted March 27, 2017 Sounds like you have the vacuum disconnect axel (CAD). It is a bit of a hassle to get them looked up correctly most kits have the seals for non vacuum CAD axels. I just bought these seals a in the last year when I get home I'll search for the part numbers. Sent from my iPhone using Tapatalk Pro Link to comment Share on other sites More sharing options...
Green Mesa XJ Posted March 27, 2017 Share Posted March 27, 2017 Mopar # 83503504 That's the big seal for the vacuum disconnect side Crown uses the same part number 2.12" intermediate axel seal. Axel shaft seal Dana Spicer part # 46470 These should be the two axel shaft seal for the front if you have a Dana 30 with vacuum disconnect . I've noticed some of of the regular shaft seals like the Dana 46470 can look a lot more aggressive for keeping dirt and mud out. I think national may be the brand of seal.

banjobill80 Posted March 27, 2017 Author Share Posted March 27, 2017 Green Mesa XJYes it is a vacuum disconnect axle. so the 46470 is for the vacuum side and the mopar # 83503504 is for the drivers side seal? Link to comment Share on other sites More sharing options...
Eagle Posted March 28, 2017 Share Posted March 28, 2017 Green Mesa XJ Yes it is a vacuum disconnect axle. so the 46470 is for the vacuum side and the mopar # 83503504 is for the drivers side seal? I read what he wrote as just the opposite, but it doesn't matter. Each seal can only go in one location. Link to comment Share on other sites More sharing options...
Green Mesa XJ Posted March 28, 2017 Share Posted March 28, 2017 Sorry the pictures are backwards. 83503504 is the passengers side with disconnect. The next trick is rigging a way to press that seal in. There is one place I am aware of that makes the tools, I've had mixed results making my own tool. Edit : when I first tried to find these seals around 2003-4 nothing was accurate on line and the local shop that supposedly specialized in axels couldn't find it in their books, I had to bring my print out from the parts catalogue. Amazing seeing as how common these axels were in jeep and dodge trucks. Sent from my iPhone using Tapatalk Pro Link to comment Share on other sites More sharing options...
banjobill80 Posted March 28, 2017 Author Share Posted March 28, 2017 Green Mesa XJ i think with the part numbers you gave me and the physical dimension i should be good to go (fingers crossed) it only took about four trips to get the rear end rebuilt turned out to be an amc 20 anyway I thank you very much for the help on this front end :cheers: Link to comment Share on other sites More sharing options...
Green Mesa XJ Posted March 28, 2017 Share Posted March 28, 2017 Glad to help! It was a huge hassle to find the right seals the first time I did the job, seriously took weeks to finally get the right seals. Eventually started keeping a repair log on my computer with the parts numbers if I can remember them. Pretty much order all my parts online to avoid the confusion the counterman can add. Sort of like how fast food cashiers get between us and what we actually order. :) Sent from my iPhone using Tapatalk Pro Link to comment Share on other sites More sharing options...
Whiz Posted March 28, 2017 Share Posted March 28, 2017 I just just bought the seals myself... Just have not gotten the guts to attempt it yet. Let me know how it goes banjobill80. Especially on the CAD side. Link to comment Share on other sites More sharing options...
