Should my brand new lower (steering knuckle) pins have any play in them. Mine sure do. They are not as bad as the orginals, but I was expecting zero play. Is that just the way it is?
Thanks.

You say new knuckle pins, were the bushes replaced as well (that is what wears the most)? I would think no play (at least that is the way I set them) but should swivel freely.

Outer lower link pins.
One of these:

I've installed it into the A-Arm/steering upright and there just seems to be an excessive amount of play, however, this is my first King-Pin car, so Im not sure what to expect.

There is no adjustment to this part.

Which way is the excessive play? Side to side? Or up and down? Could be you may have worn out bushings?

The a-arm/steering is off of the car in the Vise.
These are BRAND new. That is my question. Should new ones have play?

There should not be any noticeable play between bushing and shaft. There are some "floating" bushings that have some play between housings and shafts. I don't know if this year and application is one of them.

The thread between the bushing and pin is not a real tight fit....there will be a very slight amount of play. I will check out a genuine set later and give a reply.

A new genuine has several thousands of play. Probably designed that way so greae would flow through .
Years ago we sold 10 uppers to every lower. If they get lubed every 1000 miles they will last forever. I use a grease with moly in it for mine.

I don't feel that a few thousandths gap between pin and bushing would be noticeable unless paying strict attention. For greased joints 2+ thousandths gap is required for proper lubrication. Oil can be ~ 0.001 and still lube properly.

Thank you for the replys, and I was afraid of that.
These are new, and there is much more than a few thousands play.
I purchased them from a vendor on eBay and am very dissappointed with everything that I've tried to use so far.
The bottom bushing requires a 26mm wrench. The bushing for the top pin (screws into the shock A arm) wont even start. The threads are obviously wrong.
This is VERY frustrating.

So when I go to the autoparts store, and grease that has "moly" in it? Do you have a specific recommendation?
Thanks.
Joe

The tube will say contains moly and it is the grease required by Ford so its easy to find. Get a major brand.

Well I returned the kit I purchased from eBay and purchased new uppers and lowers from chevsofthe40s.

Guess what. Same problem with the uppers. The bushing wont even start to thread into the upper A arm.
(The old bushing hand screws in with no problem.)

I had a machinest look at the old and new bushings.
Old bushing: .979-OD .957-root thread diameter.
New bushing: .985-OD .964-root thread diameter.

I haven't called chevs of the 40's yet.

Does anyone have a 49-54 bushing that they can measure the OD and root thread diameter on.

I have this idea for two reasons:
This is the same issue I had with the ones from ebay.
(So maybe an entire batch got screwed up at the factory)

If I believe the pictures in the chevs of the 40's catalog, the bushings (and seals) look like they are from a 49-54 pin.

39-48 pin: (my original looks identical)
