Hello can any one help me on replacing the rear axle seals on my truck? I am going to do this myself but have not gotten into any yet. Are the rear axles "floating axles"? And is this a big job? What Seals do you Recommend putting back in? Also any torque specs? Any help will HELP alot..

Thanks Mike

Removal
NOTE: The single rear wheel (SRW) hub and the dual rear wheel (DRW) hub are different in appearance, however, the tools and procedures are the same with one exception: the brake disc can remain attached to the DRW hub if the longer driver handle is used to remove and install the bearing cups and seals.
NOTE: A SRW hub cutaway is shown for clarity in this procedure. However, the procedure is the same for the DRW hub.

1. Position the special tools on the inner bearing.

1. Using the special tools and holding the Handle straight, drive the inner bearing, slinger and hub seal out of the hub as a unit.
   • Remove the tools, bearing, slinger and hub seal.

1. Position the special tool into the hub cavity and onto the inner bearing cup.

1. Using the special tools, drive the inner bearing cup from the hub.

1. Reposition the hub facing downward. Position the special tools on the outer bearing cup.

1. Using the special tools, drive the outer bearing cup from the hub.

Installation

1. With the hub facing upward, position the outer bearing cup in the hub bore and place the special tools on the bearing cup.

1. Using the special tools, drive the outer bearing cup into the fully seated position.

1. Reposition the hub facing downward. Position the inner bearing cup in the hub bore and place the special tools on the bearing cup.

1. Using the special tools, drive the inner bearing cup into the fully seated position.

1. NOTE: The hub bearings must be prelubed with grease prior to installation. Pack each bearing with a bearing packing tool. Also apply grease to the thrust surface of the bearing. Use Premium Long-Life Grease.
   Position the greased inner bearing in the inner bearing cup.

1. NOTE: The grease on the bearing and slinger holds the slinger in position during seal installation.
   Position the slinger on the greased bearing with the tangs facing the bearing.

1. With the slinger in place, position the hub seal in the hub bore and place the special tools on the hub seal.

1. Using the special tools and holding the handle straight, drive the hub seal into position so that the seal flange bottoms out in the hub.

I changed the inner seals on my truck last fall. One thing is if the inner part of the seal stays on the truck, just hit it with the rounded end of a ball peen hammer. It will cause the thin metal to spread out and give you enough growth in the diameter to slide it right off...

The bearings looked fine so I just repacked them, I had around 80K on it at the time.

 

Great job with the instructions highland61.

Here's a link with some pics of the seal change. https://www.ford-trucks.com/forums/7...ake-shoes.html

 

that is real helpful .getting ready to do mine.

 

Thanks for the detailed information. Are the specialty tools expensive or can i rent them some where?

 

I didn't bother pricing the special tools, however, I hunted for a whole day trying to locate substitues based on the dimensions. Couldn't find them anywhere, checked with grainger and a few others online, nada. Wasn't going to sell my kids to even think about snap-on or mac.

You do need a good size hammer and use your old parts with some brass stock to set.

or

take the hubs and parts into a heavy truck shop....they have the right stuff.


.

 

Ok thanks I'll let you know how it goes..

 

Is this a Kit that i will be buying or will i have to buy it all seperate

 

Does any one know what size the Hub nut is so i can buy the hub nut wrench? I've called the autoparts store and they dont have a clue!! 2004 F-350 SDD DWR 6.0
