Large king pin eyes

[Stuart Giles]

As Bob says above if the kingpin eye isn't grossly oversize. stick or MIG welding around the otside of the eye will shrink it enough to be able to ream it to the original size.  Here's a couple of photos of a Big 7 axle I did a few years ago.
 this one is with the welds  dressed off prior to reaming back to standard size..
