Possible hub failure

Two years ago the right rear hub on the signature TT sheared off just inside the outer bearing after being cool to the touch at a stop 45 min earlier. Failure occurred on a hair-pin turn entering the campground so no further damage was done.

Yesterday while checking tire/hub temps at a stop I found the right front dust cap rolling around in the wheel cover. I cleaned it out and tapped it firmly home only to find it loose again 20 min later.

Has this happened to anyone else? I've never had a dust cap fall off anything before! Is there something I need to know about 2000 ALKO hubs? We bought this TT in 2011 with 75 miles on it. It was on a permanent lot for its first 10 years so the running gear is not exactly 'high mileage'.

Hopefully,

Stu

I'd suggest to pull that hub and any others that haven't been serviced recently. Repack the bearings,clean up inside and inspect the brakes. You will feel better knowing what is going on inside those areas than always wondering when the next one will fail. 10 years in storage means they need service.

If the dust cap doesn't remain seated, buy a new one.

This.
