Just had coach serviced. Should this concern me?

Far as I know, the cones are a locking mechanism for locking the axle to the hub. Once set, the cones compress around the stud, and keep the axle in place, even in the event of loss of nuts. That's why you have to smack the axle plate to release them for removal. They also center the axle shaft on the hub, and prevent the axle plate from moving and causing wear on the stud holes.

They are for retention the best I can see,but then you need to smack axles to turn loose even on the one that don't use the "dowel" as Rockwell calls it, axles come both ways bolts or wedges spacers I call them

So I have scoured the axle. I cannot see a fill plug anywhere. On my MCI 9 bus there was a fill plug. But there does not appear to be one on this one. What does that mean?

I would pull the axle and check the bearings and retainer nuts. Obviously they pulled the Hub. The axel  is the simplest of putting the job back together and they messed that up. A rear bearing failure could be catastrophic.

They don't all have a fill or drain plug fwiw

[brmax]

I think you meant secured the axle
Safely take a look at the diff lube level for starters is what my next task always was.
have a good day there

If there's no plug, you can fill the bottom of the hub while it is jacked up and at and angle. Then install the axle.

it's entirely likely there will be oil in the hub when you pull the axle. If so I wouldn't worry too much. If you have the hub at an angle, the majority or oil will stay in the hub and you'll be fine.

Time is obviously an issue with your build. Have you contacted the shop that originally did the work? They "should" come to your site and correct the issue with the axle cones and double check the wheel end nuts.

[Scott & Heather]

OK here's the update, the shop sent their mobile emergency mechanic and his truck out to the coach. He looked at the axle and determined that indeed things were not tightened quite properly. They were not completely loose but the cones were not seated. He did confirm that they did to fill the differential with oil and did fill the axles of as by leaning the coach and everything is good on that front. The mechanic that actually tighten down those axle nuts just didn't quite get the cones seated so they r replacing axle nuts and the cones with fresh ones and everything should be OK

Sounds good. Evidently the shop has some integrity. Mistakes happen. How they are handled can be the determining factor. I like that that are willing to replace the cones and nuts, but I wonder if the studs also should be replaced.

[eagle19952]

they still need to "reseat" the studs....

[Scott & Heather]

All set and all done. Mobile mechanic came out and removed axle, reseated everything put it all back together with fresh cones nuts and studs added oil and all set. Ready to roll!

I'm glad they made good and fixed it for you. In a perfect world, they would have done it right the first time and saved you and them a lot of hassle.

[luvrbus]

So it wasn't the wrong spacers just he didn't seat the cones before tightening right ?

[Scott & Heather]

I think the kid they had work on putting that side back in didn't seat them. They used the original spacers but just didn't get them right. After tweaking around with them he just got me new ones.
