I have a certain amount of play but not sure what the norm is, otherwise I will go to an oversize kit. My manual gives no specs on this clearance, thanks for the help on this matter...Glenn

The reason my lady and I have been together so long is because of the kids. Neither one of us wanted sole custody

Old kingpin must be forced out..new kingpin driven in. The only clearences involved are those between the new kingpin and the bronze bushings. At one time, there were reamers available made specifically for the purpose of reaming the bushings, once installed in the spindle, to the correct size.

Glenn,
You do not indicative the year and size of truck you will be working on. Presumably it is a 1953 Chevrolet.
1/2 ton bushings are "floating" and require no reaming; however, the bushings on 3/4 ton and larger trucks' need to be reamed (a reamer is needed).
On any size truck, if you have to use an over-sized king-pin (and it sounds like you do), you will have to ream the axle holes (or, drill with an under-sized bit and then ream the holes).
Also, a large % of well-used 1/2 ton trucks have mis-shapened/worn bushing journals in their steering knuckles. If you have this problem, ask about how to deal with it (I bet you'll be back with questions on this matter).

You would either need to use an oversize kingpin, which I believe only come in .010" over, or get steel bushings installed in the axle. I had the latter done to bring it back to standard.
If you have problems with oblong holes in the spindles, have a look at the tech tips. I believe there is a work around in there. | | |
