Steer kingpin movement

Simple way to do this yourself with no one to help. If you do the tire bar, no short little guy and feel movement. Bar needs to be long like a tire bar. Crank the brakes down tight to drum. If the movement goes away. It's wheel bearings. If you still have movement, it's king pin. A tape measure is not accurate for wheel bearings. Should be .000-.003. Closer to .000 the better.

If it still moves, up and down is not a big deal unless excessive. As @wore out said. Your looking for it to move on the axis. Up and down you could add shims. But bearing might be smashed out of it.

 

There ain't a dot officer in the USA thats gonna jack one up and check.

 

King pins are surprisingly durable and most of the time they're replaced long before they need to be. I really like the style Stemco is manufacturing that have the spiral grooves cut in them lengthwise for grease channels. A set of those properly installed and greased will outlive the entire axle.

Not my video.

 

9 out every 10 volvas I see do that. Always the left front. You can tell a volva coming at you at night from the left headlight twitching like a disco ball. I just thought it was part of the glamour and great ride everyone claims they have.

 

They must have been really loose. I test drove a 99 W900 once that was a complete neglected ####e show. When I grabbed the steering shaft with the truck idling and turned the wheels back and forth, the king pins were sloppy as all get out. It doesn’t sound like an LEO is going to catch yours unless they jack the axle off the ground.
