LS 4047R control arm break

You can go the bearing number route, or after removing the bearings, measure them using calipers. Alternatively, you could take them into a bearing supplier and they can match them.

As far as "drop-in," no. The bearing on the king pin will be pressed on. The races in the "king pin housing" (what we have been calling the control arm), are also pressed in. Same with the seal. But that cast is easy enough to do with a socket and light taps with a hammer. The bearing on the king pin will need to be pulled using a bearing puller, and the new one installed with some pressing. You can use a socket and hammer, but at your own risk. Just make sure your socket or pipe only contacts the inner ring of the new bearing. There should also be a bushing inside there that is free floating. Thats number 18 in ptsg's post above. All that is for the king pin housing/control arm. I forgot that your hub also needs rebuilding. Probably need the dealer (either LS or NH) for that.

@Avenger, absolutely, I had a look at the hub and saw the press fit sleeve. What I meant by “drop in” was, would the parts be identical from NH to LS. My dealer has the hub now, I feel like they may still have it months from now, communication and timeliness are not there strong suits. I’d really like to get the parts and do it all myself, I work with industrial millwrights so i’ve got good help that way. I am going to give the dealer to the end of the week and if they don’t have any good answers i’ll get the hub back, order everything and hope for the best.

Finally have parts in hand and am trying to replace them. I cannot sort out how to get the taper bearing (40010341) out of the hub assembly. I’ve removed the cover (40036079) from the gear case (40008939) thinking it would drop right out the bottom, sadly, that is not the case. I’ve tried turning it to get a better angle for removal but the diameter is larger than the hole. It seems odd to need to remove the whole wheel hub assembly just to get that bearing out, that would be the only other option.

Got the hub assembly apart, gear is out. Will have to pull the bearing on the main gear tomorrow and get that gear off, there is a ton of metal sludge between it and the housing.
