I am getting ready to do a fair amount of work on the suspension of my 1972 280 SEL 4.5L and I want to know how to check my kingpins to see if they are in need of replacement. In a perfect world, I'd simply replace them and not worry about it - but I am strapped for money and want to avoid spending more than is necessary.

I've done this,
No matter what, if worn or good you must get them out, clean, and in your hands. then,
Inspect shaft for wear. then check bushing size.
(micrometer stuff OK with it?)
Remember the shim stack sequence.
Clean thrust bearing.
This is a fairly sophisticated job for perfect success.

I have dissasembled and rebuilt my kingpins. There is a very slight interference fit between the kingpin and the spindle and the thrust washer setup. If you remove your tie rod and move the spindle there should be no play in any direction and a slight drag when turning the spindle. Otherwise you will need to dissasemble and measure. What usually wears out are upper and lower link pins and carriers.
