My '89 F-Superduty (That's what they used to call the F450) has a Dana 80 axle. Was the Dana 80 an easy swap?

He said it's an f350 DRW with a D80.. Thats factory not swapped.
Do you have a pic of the two piece? I only thought it was one piece.
I had bought a D80 and D60 SRW(hard to find) for a swap on one of my dodge trucks.
You're talking about this right?

Not factory in a '91 F350.

Interesting.
I was curious after your response so I looked at the blue oval guide and I see the following for the D80
1988-2009 Ford F-350 (Rear)
1998-2011 Ford F-350 DRW
I'm guessing it was a SRW option in 91 and DRW starting in 98.
Thanks for that.

Perhaps he removed a Scotseal and replaced it with a standard seal? I've heard of people referring to Scotseals as a 2 piece, even though they're a unitized construction that goes in as a single assembly. Likewise, I've seen several posts over the years of people replacing a worn Scotseal with a "normal" style seal from the local discount parts store, then having massive leak issues immediately.
Alternatively, and just taking a guess here...I wonder how close the dimensions are between a D60/D70 and a D80 or Sterling and D80. I just looked up a '91 F350 on Autozone's website, and they don't even show a D80 as rear axle options. Only a tranditional style wheel seal for a D60/D70, or one that appears similar to a Scotseal for a Sterling 10.25. Perhaps one of these has a close enough OD to work, but is too large on the ID, thus causing a leak?

My '91 F350 dually has a 1 piece seal like Hacked has in the pic.
Listing is wrong. 88 is when the F-Superduty (F450) began, and it has the dana 80.
