anyone know where I can download a schematic for a rear axle seal change for my 06 2500 mega 4x4. Large pumpkin, cant remember the 2 different dimentions of the difs. Or does the axle have to be removed from the dif to replace the seal. Where is the seal located- in the housing, attached to the axle???

Thanks

 

The rear axle is a full floater - there are no axle shaft seals if that is what you are referring to. There are wheel bearing seals which are located in the back side of the bearing hubs. You will have to unbolt the axle shafts and remove the bearing hub assemblies to access them. The only other seal on the axle assembly is the pinion seal.

 

Thanks. After the hub is off is there any specialty tools required to get the seal out and reinstall.

Cheers

On my 2003 aam 11.5 both rear hub seals started leaking in the first 50,000 miles replaced with dana 80 seals no leaks in the last 123,000 mi.
I realize this is not the correct seal but I had them on hand and the dimensions were very close so I gave it a try worked great.
