Just curious...I have a set of alloy mr03 knuckles that have some play in the inner sleeve. Not only do they have play on new kingpins they really have a lot of stiction.

Anybody ever fix a set?

if you have PN Knuckles, you can buy a new insert:

I've had to replace the PN inserts before. You just need to polish them with a kingpin because they bind when new.

For atomic knuckles, this is what Tj did: basically using the PN mr02 inserts in the atomic 03 knuckle.

Thanks for the info and link...I don't exactly know which knuckles they are (bought the car from pinoyboy) so I'll try a couple different inserts.
