Possibility of crankshaft sprocket slipping on crankshaft snout

Most crank sprockets are fixed to the crank with keyways afaik. It is also easy to have a press fit such that they won’t move, but then pullers are needed for removal. An interference fit can be ...

Did I remove this hub bearing wrong? (post-mortem)

My guess would be that the assembly came apart for two reasons. The wear in the bearing caused some play between the inner race and the bearing shell. Some corrosion resulted in more resistance ...

Do you need to grease wheel hubs

It depends on the bearings, if they have rubber seals on each side (ie sealed for life...) then no, but if they are "open" then you need to have grease there.

What are the extra "bumps" on this trailer hub?

They may just be an artefact of the manufacturing process. The hub looks like a casting, and if it was cast with a central hole to save machining time later, you would need to pour the metal evenly ...

Does an axle nut require a "deep" socket?

No, any old 32mm socket works on Subaru axle nuts. If you look at the photo you supplied, there is a notch in the axle (at about 9 oclock). The axle nut will have been hammered into that notch to lock ...

The purpose of redundant holes in some hubs and brake rotors

Some rotors have an M8 threaded hole to use for helping to remove the rotor from the hub (and brake drums sometimes had one or two threaded holes for the same purpose, but not M8...), but most just ...

Choosing replacement seals for trailer hubs?

I would measure the diameter of where the seal locates, the depth available for the seal and the diameter of the shaft. Any good seal selling place can match a seal with that along with the speed of ...

Servicing loose trailer hubs

From your description, it sounds as though you are spot on: the hubs were not tightened correctly by the last person who serviced them. As for the maintenance and reassembly: Completely clean the ...

Can broken wheel hub stud cause other wheel hub stud to break?

If you have 2 snapped studs then the last tire tech working on your car over torqued all your wheel nuts. The ones not snapped are probably stretched. They stretch and then fail. I'd replace them. ...

What is the difference between a worn wheel bearing and a worn wheel assembly?

I would presume they are talking about the same thing. Really the only things that can wear in the hub are the bearings and oil seals. It used to be possible to replace the bearings in the hubs on ...
