Well the 10.5 rear end in my 03 is leaking gear oil out the axle shaft tubes. Has anyone put new seals in these before? I know its a full floater axle so there aint much to it but want to make sure I have everything i need before tearing into it since its my only vehicle. Spoke with dodge and they dont have a parts book for sale and suggested i try the website, that worked out great......
Any ideas?

 

The part number for the wheel bearing seal is 5086773AB, and the part number for the gasket that goes between axle and hub is 5086767AB. I think you have a 11.5" AAM if you have a Cummins, but it doesn't matter both 10.5 and 11.5 use the same seal and gaskets.

 

See, it's nice to have a parts guy here!!

 

shoot me the last 8 of your VIN and I will check the build sheet for ya

 

Thanx for the help guys, i went to the dodge dealership today and spoke to them. They gave me an exploded view and the seal number. Cost 22bux for each seal but they only had one in stock. Aint nothing to changing them, iv done a few ff 14bolts before. Last 8 digits are, 3G760213

 

It is a 10.5 rearend? I've looked up a lot of parts for Dodge trucks and never seen a 10.5 behind a Cummins. I'll have to tell my guys at the counter, we always went by gas trucks had 10.5 and Cummins trucks had 11.5, if the customer didn't know which they had. Makes me feel a lot better about wanting to swap in a complete set of Power Wagon axles. I was always concerned about downsizing the 11.5 to 10.5!

 

'03 and '04 SO trucks have the 10.5 with the Cummins. I have the SO with a 10.5 rear and a 48RE and no issues to date...........

 

just verified that it is a 10.5 rear with 3.73 gears.

 

Alright changed both seals today, preety easy job, not much to it. Seals cost 33 bux each from the dealer. Thanx for the input guys.

 

mine is a 10.5" also. I know everyone says different stories on what years the 10.5" was used and to my knowledge the 10.5 was only used in 03 S.O. trucks with the 250hp engine. the 03 H.O. engine is 305hp and that is the same engine as the 04 S.O.(305hp) I have yet to hear of a 04 or newer truck that has a 10.5". They were all 11.5" I think. I think there were too many gear howling issues with the 10.5" and Dodge switched all to the 11.5". I had 3 sets of gears installed under warranty to get the howl out of it. The first was a factory issue and the other ones were Dodge tech error. I finally demanded to see and be happy with the wear pattern before they re-installed diff cover. They did it 2 times before it was even close. Correct rear gear setup is a special talent. I have set up hundreds mostly in Chevy 10/12 bolts and some Fords and I have aquired a "feel" for it. I can usually put it in and look at the pattern and only re-shim once it get it perfect. Some installers re-shim 4 times or more, if they do it right at all...

 

I have the 10.5" in my 03 SO. I installed the locker form the hemi power wagon. I pull a 12K 5th wheel RV and haven't had any issue. I'm now on 55K miles with the locker and no issues.
