4th gen rear axle seal

[Randomrunner12]

Hey guys,

I've searched and searched and still not really finding what I'm looking for.

Does any one have an IPC for the rear axle on the 2012 2500? My diff has the 3.73 gears and a 14 bolt cover. I think it's the 11.5 axle but not entirely sure.

Any and all help is appreciated. My driver rear seal is leaking and I'd like to get all bearings, seals, fluids and even the diff cover replaced In a timely manner.

No need to replace bearings unless they have failed.The rear diff gasket is reusable.Remove the axle flange bolts slide out shaft,remove the retaining ring.Remove the lock key,remove the nut using specail tool#8954.Remove bearings and hub.The hub seal may separate.Reverse procedure to reassamble.I always repack the bearings to ensure they will be lubed before the gear oil reaches them while driving.Torque the nut to 37 ftlbs then back off approximately 50 degrees then to next slot for the key.

Sir Bob4x4 you rock. Thank you. Right now it's a slow leak/seep. I spray brake cleaner on it in the mornings to monitor the flow.

I am working on sourcing the correct part numbers. Right now all I have found are I should buy the national brand ones since they are USA MADE.
