Have the bearing been serviced and the lock tabs reused, not replaced?

That would be the problem, if you reuse the lock tab you usually end up re bending the same tab and they can shear off. Lucky the bearings only came loose, the broken off tab can destroy the bearings.

I have not touched the front bearings since owning the vehicle, (2yrs),,,going by service schedule they are due to be replaced at 200.000ks which it has just turned over, Supposingly been dealer serviced every 10,000ks...someone didn't get it right at some stage maybe.

couldnt swear to a 100s service schedule but other tojos they are a 40k service item
(ie 40,80,120 etc)
my ex had them stuffed up after the 40k service and
KALAMUNDA TOYOTA
denied all knowledge until it was pointed out they did the 40k service no one else would have touched them and the vehicle had had nothing but gen toyota sevicing
funny seeing their faces when they wriggle as hard as they can but end up against the wall with no option but to pay all repairs

Locking tabs need to be replaced as part of wheel bearing maintenance. They cost next to nothing.

As the others have said Axle, a new tab washer. The both nuts should also be torqued up with a correct fitting socket. If the lock nut is not tightened correctly it will allow both nuts to move. Cheers,bob.

Axle!!
That must have been the passenger side, lucky it wasnt the drivers side where it could have locked up the wheel, unless of course it has a Left hand thread.. Michael

Axle,
I had one fail ( don't remember why it failed) and the two nuts screw off allowing the wheel and hub to be retained only by the disc brake being trapped in the caliper.
It was driving normally and I only noticed something was wrong when I saw a pool of oil/grease on the ground at a morning tea stop.
A careful trackside repair then a drive to Cohen to get the bits to repair it properly.
It was an old 60 series and that was to only thing that ever gave me grief.

Sounds all to familiar, but for me it was the rear passenger side on the 60 & drum brakes so this allowed the whole wheel & floating axle to move out from the car....
We were just south of the
Jardine heading south, but had to jerryrig a large log under that corner of the car & put the axle & wheel up on the roof. We got about 10km & eventually the mechanic from
Bamaga arrived & got us on the road again.
All good fun though!

Whilst changing the locking tab is undoubtedly good maintenance and should be done, it is not necessarily a must do. If an unused tab is able to be used upon reinstallation then there is no detriment to its effectiveness.
However as stated they are cheap and if the task is planned then new washers should certainly be used.

hi offtrack
couldn't agree more no matter what vehicle it is
yes as you said if the adjusted bearing finishes with
the nut at a different lock -tab it is quiet ok to use the new one
but never try and re-use one as they will and have been known to break off
some vehicles have lock plates that are secured by phillips head screws which i have found to be a much superior system
ford /mazda and if memory serves me nissan navara
cheers barry
