D60 knuckle

[Mastiff]

Just finished rebuilding one side of my D60 knuckle with all new bearing, kingpin, bushing, spring, etc. I know it's kind of hard to describe in words, but would like to make sure the turning resistance of the bare knuckle is right. The way it seems now is like I can turn it fairly easily for a few degrees of rotation, then it sort of "catches" and the resistance is more. Is it normal to have a little slop like that? My only guess as to what it might be is the ridge on the kingpin bushing moving in the slot?

Sounds like you may be right. Mine was pretty consistent - as far as resistance. You may want to take it apart to check.

Looks good, by the way. Don't you hate it when you paint it all up and then scratch your paint off spinning it on the jackstands?

Not sure what could be done about it. My other knuckle and bushing are still apart, and the ridge on the bushing is narrower than the slot, it's definitely going to move.

I do have to take it apart anyway. The reason why is obvious in the picture.

It's standard procedure for me to paint parts all pretty and scratch half of it off during install. I'm just going to touch up the scratches with a paint brush later.

spindle studs?

spindle studs?

Yup. I'm learning all kinds of things the hard way on this project.

Anyone else have thoughts on the rotational resistance, and the bushing rotating in the knuckle? I can snap some pics of my other knuckle and bushing if you don't know what I mean. I think the rotational resistance comes from the bushing pressing against the kingpin, but this requires the bushing to be fixed against the knuckle. The only thing that make that be true is that there is a ridge on the outside of the bushing that fits into a slot in the knuckle. The ridge is thinner than the slot, so when the direction of rotation is reverse, the knuckle can move until the ridge is on the other side of the slot. I _think_ this is the slop I'm feeling.

I just rebuilt my 60 hub to hub replaced every seal, bearing, and upper and lower king pins. I got one side all together and everything was great no issues. Then Once I did the other side I notice the same catch sensation you are describing. Couldn't figure it out so tore it all done and didn't find anything wrong. Put it back together same thing couldn't explain. Only thing I could think of wasn't enough grease on my king pins since I hadn't filled them through the zirk fitting yet. As soon as I did that and worked the knuckle back and forth a couple times it went away. My only thing I could come up with there was a dry spot on the king pin bushing causing the "catch" sensation. So if you haven't filled them with grease yet maybe same thing

damn that axle looks brand new

Here's a thought. On the passenger side, I did not purposely put any grease on the outside of the bushing before install, but I did on the driver's side. Maybe if the cap is torqued down dry, the outside of the bushing seats tightly against the knuckle, but if it's all greased up, it can rotate and has to rely on the slot in the knuckle to prevent bushing rotation. Hopefully that makes sense. Anyone aware of any specific procedures about where to put grease during install? On the driver's side I just went nuts and put as much grease as I could all over everything. Maybe that was a mistake?

Not a mistake. The grease is gonna get there anyway once its all together and running.

Yeah, seems like it. The ones I pulled out were certainly greasy. I'm just trying to find an explanation for this. Maybe the passenger side will end up acting the same way once the grease works its way in. Or I could pull it apart and make it greasy as a test.
