My understanding is you purchase a new seal tone ring replacement.  When mine were replaced, that was what was explained to me.

There are plane truck seal replacements available but you loose ABS function if you use that seal.
Rudy, any chance you have a part number?  The seal I purchased did not come with the tone ring.

Don't forget to grease the lip of the seal.

That discussion is for the ABS sensor (i.e. picks up signal from tone ring).

And on this thread he is looking for the tone ring itself.

ON EDIT: Michelle is correct-- post #17 is a parts list  (for his 2000 U295) MAY be the same for the 1997 U320.

Correct.  I do not need a sensor at the moment....at least I hope not.  I need to determine if I need a tone ring with the seal installed, or if I can press the seal out of the existing tone ring and press in the Stemco Voyager 393-0173 seal.  The tone ring is not a cheap thin piece of metal like some I have seen, so it seems like it is re-usable.  I do not have a press.  I have tried using a brass drift without success....might just need more effort, but I think I will try to find a shop that will press it out for me unless others have ideas on how to do this "shade tree" style.

OK - wasn't sure if John Haygarth's part list posting in that thread might have included the tone ring.  It does call out a "sensor ring"; I wasn't sure if that was the same thing.

Yes, I think the sensor ring, exciter is the same thing as a tone ring.  Good to have that parts list, but hoping I do not have to purchase that part.

Michelle,

Good catch.  While the thread is about the sensor, John's post #17 (for his 2000 U295) with part numbers MAY be the same for the 1997 U320.

I went back and edited my post.

Thanks.

Can the outside of the seal be cut to relax it's hold on the ring to remove it? Fine hack saw or hand held cutoff wheel. Can't see the side in photos to tell. Also you don't need to go all the way thru, should fail when it's close. In looking closer the seal is inside. Cutting it will relax it's hold, but you will be forced to use a hacksaw blade, possibly backward in the frame to allow clearance

DayD,

The trick is to get a heat gun (like a mac daddy hair dryer) and heat the back side of the exciter/tone ring. NOT RED HOT just warm enough to loosen the Locktite so you can gently press the seal out of the tone ring. I have never tried it with a hammer and punch  as you need to keep the parts square coming out and going back in as you don't want to here the tone ring go TWANG.

I have a great heat gun.  Never thought about using it or it having Locktite on it.  Thanks for the suggestion.

I did one like that a while back and the seal can be driven out of the tone ring and then you can see how it all goes back together

Found a local shop to press the seal out of the tone ring.  Super helpful crew, but this configuration where the gasket is pressed into the tone ring was new to them.  The number on the current seal was National 370181 BG or DG...hard to tell.  Since it appeared to have been previously replaced and was leaking again, they wanted to confirm the installed seal was the correct number.  He also wanted more info on the correct installation of the tone ring.

The shop crossed the National seal to an alternate number but none was locally available until later this week.  He suggested I call Foretravel to confirm the installed seal was the correct one....which I should have done before I ordered the wrong seal. 

Foretravel gave me Meritor part A1205J2272 and the local shop confirmed the number they found was an alternate, so they ordered it for me and I will let them install it in the hub since they have the correct installation tool.  It is the least I can do since he did not charge me for pressing out the seal or re-installing the tone ring and spent over 30 minutes looking for the part.

He also offered advise on re-installing the hub on the spindle to prevent damaging the new seal.  He said to push it on straight, spinning a little if needed, but not to rock it.  Suggested using a floor jack or re-installing a wheel to keep it aligned and to support the weight, and using a greased board to slide it.  Definitely extra work since the wheel has to be pulled back off to install the caliper, but considering the hub assembly weighs in at 140 lbs, it is probably the approach I will take.

For future reference, attached is a list of alternate seal numbers for Meritor part A1205J2272

The floor jack method on a piece of plywood is better than using a wheel. You can see the alignment better with the floor jack. You have to align height and parallel to go straight on. As soon as the hub is on the spindle enough to put on the outer bearing, it will guide you the rest of the way.

Finally got the hub reinstalled yesterday. I let the shop order and install the seal in the hub.  He charged me $50.00...which just covers his cost for the seal, but he removed the old one from the tone ring and installed the new one in the hub too.  What I thought was red locktite on the seal is just a sealant.  It was on the old and the new seal, but I know there is no way I would have gotten the old seal out of the tone ring without a press.  I tried the heat gun, mapp gas torch and big hammer, to no avail.

I ended up using a floor jack to lift and align the hub.  It was a little precarious with that 140 lb hub resting on the jack and trying to align and push, but it worked nicely.  Sealed up the end of the hub with gray RTV designed or gear oil contact.  Letting it cure and will re-fill the diff later this week.

Thank you to everyone for your contributions and especially to Pierce and Craneman who gave me confidence to do this myself.  I like doing my own work whenever possible and practical.  This was my first foray into such a project on a vehicle this large and I was in over my head a couple times.  I appreciate all of the support from this forum.  This project took me several weeks.  Was not in a hurry and holidays got in the way, but glad to have it done.
