I recently got a dana 70 out of a 90 F-350 for the powr-lok and 4.10 gears. While tearing that axle apart I noticed that ford must use a different kind of retainer to hold the hubs/ drums on. They use a ratcheting type two piece nut/ lock ring instead of the huge nut with the nylon threads and key that is on our trucks. they look like this.


I was wondering if they would work on the dana 70 from my truck that I am rebuilding. The threads are the same, so they fit on. It seems to be much more effective at retaining the hub/drum. Just wondering if anyone has used these because I need new axle nuts of some sort and the less I have to buy, the better

I have had about every kind of axle made apart, at one time or another, and I have never seen a bearing adjuster/lock nut like that before.

My guess is that it is some type of aftermarket "upgrade".

My Dana 70 Ford has the single nylock nut with the little easy-to-lose drive in wedge-thingie; I hate them.

The nuts are of some soft metal that allows the bearing to eat into the backside, thus loosening the adjustment as it wears the groove.

By far the most superior adjusting/lock nut set-up available is the double-nut with folding ear lock-ring.

Those nuts are HARD and I have never seen a wear groove in one, NEVER

Unless they can be found on a junker axle, they are quite pricey, something like seventy-five bucks a side; but, they are well worth it.

To answer your question, if the threads fit, go for it.

BearKiller, those nuts are on all the newer Fords. I am not sure what year it started, but I know for sure that from 2000 up I have been seeing them on the Fords. Ford calls for them on the Dana 60 and up. There are some axles that still use the standard 2 9/16" axle nuts or the 3 1/4" on the F53 chassis(motorhome)

I see them more often on "Dana 60"'s. Nice idea, but the 4 holes for the socket are spaced a little further apart than a standard front axle nut. The socket for them have a pilot stub to fit in the axle tube.

Those are the ones I have on My 4.10, it is factory item I believe and You can get the socket for this at any autoparts store it is a big socket with 4 pins coming out of it to help lock it back on place it is done in 3 steps and the #'s are 90-100lbs then back 1/4 turn and then 25lbs.

thanks for the replies! I think I will go ahead and use them since they appear to be in perfect condition. I was looking at getting the double nut set up like you were saying BearKiller, but these seem just as good and are free! They came out of a dana 70 under a 1990 f-350 ambulence. Maybe someone upgraded it to the newer style? thanks again for all the info!

IIRC our D70 rears use the same thread as our fronts.

You could switch to the dual locking nuts for a Chevy D60 and be better than the nylocks.

IMHO anyway!.

I prefer the GM style over the wedgie type:

The Dana 60, 70 and 80 use the same nut ( i have put them on all of them my self). I use the nylock nuts on F&R of my truck and have never had a prob. You can get the exact preload insted of having to go to tight or loose with the dual nuts ( yes I know you can turn the washer over to change the location of the holes but it is still never quite right). just my $0.02

The nut used on some fords like in the pic is like that used on many big rigs.

My '92 F250 Sterling 10.25" used them... while they are a pain to get off (w/o the socket), they do NOT back off!

anybody know where you can get a socket to fit these nuts. My local parts store only had the smaller 4 pin socket for d44's and such.
