As far as I understand it it's just a matter of preference. The metal ones cost more but will last a lot longer. Either way, you have to have them reamed out to fit the kingpin by a machine shop once they are pressed into the spindle.

originally you would have had the metal bass bushings. the spindle will have to be reamed to reinstal the new metal bushings. the plastic bushing can be install by ahnd and need no reaming to fit in the spindle. from what i have been told the plastic bushings only last about a years worth of driving before the plastic wears out and you need to go back and have the brass metal bushing put in.

ok
the problem is the there is a play up and down in mine....only a year hmmm

up and down would mean the lower bushing/bearing has went bad. it sits between the lower spindle ear and the i beam.

The way I understand and have seen it done is that you don't ream the spindle out, you press the bushings into the spindle and ream the bushing out, not the spindle. Or am I missing something?

i have no idea what the actual process is. i just posted the basics of them and what the differences are between the two types. plastic and brass metal ones.

this is what my truck is doing. this isnt king pins?

[fordman]

i thought you said the tire wobbled instead of having slack up and down. to check king pins you jack the tire off of the ground. then push and pull in and out at the top and bottom of the tire. if it moves in and out then the kingpins or wheel bearing have slack in them. to tell if it is king pins you can watch under the truck as someone else moves the tire in and out. that way you can tell if the hub is moving or the spindle or both.

yea its wobbles now cause i didnt install the bearing right. n the morning im breaking it back down and going to attempt to set the races correctly..b4 i messed with it, there was a up and down motion..

That's right. You ream the bushing. I had all that done at a machine shop when I did mine.
They pressed out the old ones, pressed in the new ones, and then ream to fit the new kingpins.
The proper fit for one is so it's just tight enough to hold the pin in the spindle under it's
own weight standing vertical, but loose enough to be able to turn it with your fingers.
You want a fairly snug fit, but not so tight that it's hard to turn.

The bearing should have shims to make for a tight fit when assembled. There should not be slop
up and down. I think mine took one shim if I remember right.. And yes, it does matter which end of the
bearing the shim is placed, but it's been so long since I did mine, I forgot which side.. But I think the shim goes
on the closed flat side.
