Dust Caps

Are your axles the originals?

I will check tomorrow as I think our caps stick out more than 1 inch from the hub. But, you know how memory can be.

Andy, Did you ever find out about these caps? Ed

Related question:

Visited our '79 Argosy 27 in the storage yard today with the plan to make sure everything ok before we head out for the first time of the season.

When going to check air pressure, I notice that the dust cap, and the bearing buddy (or similar equivalent) (was this standard?...I've emailed the previous owner to ask if he put it on) was off on one wheel.

I have no idea when it went missing...October was when it was winterized and put in the storage yard. I had other issues on my mind and didn't check, or did I think to look during the winter when I checked it then. But the dust caps were Grease had leaked up the hub a bit, but wouldn't it have splattered on the (white) wheel if it had come out when it was rolling? As late as Labour day last year, it was certainly on there, and went out for one weekend after that before winterizing.

Really has me perplexed...a dust cap sure, but a bearing buddy which is hammered on (I believe) to come off? Surely someone didn't steal it for their own use? Although, if its not a stanadrd size...and rare to find, you never know.

Are dust cap standard sizes? Original Airstream Axis, OEM size 7.00 R15 tires. Something I should be able to pick up at an RV dealer locally? Obviously would like to have it before next weekend.

Should I be servicing the bearings right away, or can it wait? I had them redone and repacked last summer, it hadn't been done (but were apparently still fine) for about 7 years prior. We drove about 4000 miles last summer on them, won't be as much this year. Being a bit of a rookie, wasn't sure what I was looking at earlier today, and what I exactly I was missing, so now that I have taken a picture, I may go back and make sure everythig else is there as far as the bearings go. There is still a large amount of grease on the bearings it is just getting a dust cap fine at least for the short term, or should I be looking at something else to make sure everything is ok before I go the 2h drive next weekend.

The other issue, as mentioned, is how something like this bearing buddy could come off in the first place (assuming it wasn't stolen).

Any help, guidenece, thoughts, would be appreciated.

Edit: Attached are the one missing the dust cap and missing the bearing can see the grease leaked up to coat the hub. The second picture is an ok wheel with the bearing buddy (and dust cap removed) in place.

After another visit to the trailer, armed with info and a set of 1.98 bearing protectors and "caps" (thinner plastic that stretches, not a hard cap) and a tape measure, found out that 1.98 is too small. The outside diameter of the ones currently on there (in the pic on my post above) is 2.24".
I quickly went to another store, but they only had 2.04, 2.44" variatons in addition to 1.98".

It appears 2.24 is a listed width on the bearing buddy website, so I may look into that, but for purposes of this weekend, it won't work. After calling around locallay, found an axle place, and they told me it really is a rare size, and they could order it (or caps that fit) through the same channels online that I would, but nothing local.

The caps that came with the 1.98 protectors are also small diameter wise, and, as one of the posters above said, not deep enough of an offset. Again, the cap would be a different size too then one that would fit a 2.24 bearing protector, as the exposed bearing would be a different size.

I contacted the previous owner, who's been very helpful in the year that we've bought it from him. He has the original Argosy caps (his father had put the bearing buddies on years ago, but he kept the originals), however they actually bolt on under the 7 nuts on each of the wheel. I may end up getting those at some point, but its not possible to have that fix by this weekend.

Outside of welding something together, any other options for a makeshift cap/protector for a short 300 mile round trip? In addition to the dust, there does plan to be some rain that we'll be heading through, and really don't want those bearings left exposed.
