Difference between "Kingpin" and "wheel" bearings

Hello there guys ! just wondering what the difference is between Kingpin and Wheel Bearings !? Have a few jobs to do and want to buy the right parts ! Many thanks guys !

The kingpin bearings are too and bottom of the swivel hub the wheel bearing is same place as on every other car, what's the symptoms? If its grease on back of the swivel hub it'll be kingpins it is bearing noise it'll be wheel bearings

When checking mine I shook the top of the front wheel back and forth hard and could feel the clunk of movement as well as hear it knocking. Also I had the visual of the oil weeping from the back of the knuckle housing- for quite some time too. I got SWOM to do the shake in case I was being heavy handed and she could see and feel it. It seems to me that wheel bearing problems will be mainly noise of a grinding sound or a feel of roughness. Plus which, Jimnys are famous for going through king pin bearings (it ain't the king pins themselves, they are made of substantial steel in contrast to the majority of the car's construction).

Best way to tell which is shot is watch or put your hand where the brake disk goes through the caliper when you "wiggle" the wheel. If there's movement between the disk and pads it's the wheel bearing, if the disk and caliper move together it's the king pins.

i had no movement in mine but oil on the swivel hub so changed and found this

no mement in the other side or oil on the swivel but for the cheep price im doing that side soon also i noticed the bottom was knackered but top looked ok dont know if for a bit of a bodge when doing one side you could hop to the other and stick the top one you just removed in the bottom of other side got to be better than the one thats proberly in there now

Many thanks for the quick and very helpful replies guys ! My first thought is correct then, my Wheel Bearing has gone, another job to do ! Ah well it shall keep me busy and my free time limited ha !

Thanks again friends, by the way it now also looks like my King Pin bearing on the other side has gone ha !
