Oil spray out of rear lug nuts

I'm guessing they meant flange gasket.

Not much can fail on the flange itself.

Probably. I’ve only had two heavy duty rear axle seal failures. one was an inner, one was an outer. The inner failure caused a fire from brake heat. [emoji33]

I have never seen a over the road truck without floating axles.
There may have been back in the very early days of trucking, but nothing in the last 75+ years.
That's a fact.

Where that exploded diagram is showing an 'O' ring, mine had a paper gasket, with holes for the hub studs to go thru.

With the web at your fingertips, to see that your wrong about full floating axles, you choose to argue.

For $125 an hour, I will let you talk, while I do it right.

Yes some have an o-ring, some have a thin paper gasket, some just have rtv or form a gasket type sealer.

Everything from 3/4 ton pickups to dump trucks, motorhomes, and over the road tractors use floating drive axles similar to the pic I posted.

Because on floating drive axle set ups all the axle has to do is drive or motivated forward or backwards, the hub rides on bearings on the machined end of the axle tube which actually carries the weight of the vehicle instead of the axle shaft and flange.

Like the others have said this is a common issue with these large full floating rear drive axles.
I repaired an oil leak on the passenger side of our Eaton rear drive axle.
First I jacked up that side so less gear oil would run out. Then I removed half the lug nuts so the chrome hub cover would come off, then the axle retention nuts. The axle then slides out. I spent some time cleaning and scraping off the old paper gasket. I applied Ultra Grey RTV and reinstalled it. It took less than 1 hour.
Make sure you check the differential gear oil level when done.

This is a picture of what mine look like, although this one seems worse that what I have typically seen. Not the usual from lug nut only. I will have my mechanic check it out this month.

Did you buy your KW's from e-Bay? Winross trucks don't have full-floating axles.

Reminds me of a guy I worked with for awhile. Said He was an O-O and blew his engine, couldn't afford repair and yadda yadda. Someone casually asked what engine he had. "Er...I forget." Think he was full of male bovine excrement?

I'd like to see this Ram 3500 that "does not have a floating axel". Sounds interesting. All the "3500's" I've seen over the years had either Dana 80's in the earlier ones or AAM's in the later ones. Both being full floating style. I know some early D2500's were called "light duty" and used semi-floating rears, but not the one tons.
Not a Dodge expert though, just seen some stuff over the years.

You more than likely have the same axle flange gasket leak we are discussing in this thread.

Hi, I think this thread is the perfect example of the two types of owners we have on the board. First are the old-timers who know their subject but who feel that everyone, even the rankest newbie, should have a full mechanical understanding of their vehicle plus the tools to perform major maintenance. I understand that it's fun for them to debate the underlying issue -- and exchange barbs with one another -- and for one old-timer helping another, this works perfectly.

The second group are the first-timers, the non-mechanical, the lazy and those under warranty. I am definitely in this group. So, while I stand in awe of those who can torque the what-not and hoo-doo the suspension, I need more basic help. This help will mostly be diagnostic since almost any major repair for me is going to require a mechanic.

I plan to indicate which group I am when I next ask for help. No need for the detailed instructions on repairing my Cornerstone myself. I wouldn't dare.

I totally agree. I’m not mechanically inclined at all, and really just wanted some basic input as to what it might be when I made the original post so that I could talk to them more intelligently at the shop. I can’t do any of the stuff that was suggested, and if I had tried it would have been a disaster. Thanks for saying what I’ve been thinking for a while now.
