2nd Gen Non-Engine/Transmission Rear Axle Seals

[KMacnicol]

I have to do rear axle seals on my 3500 2WD dually this weekend and was wondering if there is any special tools that I will need. I did a search and found some things about a 2 9/16 socket but they were all 4x4. Is it the same differential? Thanks

The nut retaining the bearings is a 2 9/16. It is held in place by a couple little parts that "lock" it to the housing. This is a weakness in the Dana 70/80 rears axle outer ends. I recommend a Quad 4x4 kit to upgrade the retaining system. If the stock clips get loose they can wreck your day.

I'm looking to do my one of my 2500's rear seals again this week myself.



I need an upgraded seal, what do I need from http://quad4x4.com/Dodge Rear Axle.htm

I will be doing mine again soon. This is what I ordered:

QK4012 Same as QK4011 without socket

QK8326 Oil Bath Seal Upgrade Option for Dana 70 and 80 axles with Single Rear Wheels

Can anyone tell me more about this oil bath seal? Is it a seal like some Fords use where the rotating parts of the seal are within the seal and don't actually spin on the axle spindle? Also does anyone have a part number other than Quad 4x4 for this seal?

Are you sure it's 2 9/16 on the hub nut socket? I did my rear seal in March and it needed a 2 1/2 hub nut socket. I have the Dana 80, maybe mines different.

The # that I previously listed was for the upgraded seal if you were ordering a bearing kit also. The seals by themselves are part #QK8340.
