Hi,offside kingpin,had alot of play seamed to be top bush,removed driveshaft and top cap missing,having prod around and stuck a tapered punch in kingpin hole to see if could get grease out anywhere else rather than top,once pumped grease gun it pushed pin out the top,now all apart and clean the top bush is badly worn ,the bottom slightly but not so bad,the kingpin looks ok with no burrs and goes through the suspension arm with the pressure of one hand,its not sloppy but not tight,measured the pin and seams about 16.98,just wondering if a standard pin kit will do or a 17,1mm oversize,not sure how tight in there they are supposed to be :?:

Sounds like the hole in the arm is too big. Go for oversize
Good luck

Thanks for reply,not that great at mechanics,if the car was brand new and the pin was 17mm what would the diameter of the suspension hole be,would it be exactly 17mm also,just trying to find out what size the hole would idealy be for a 17.1 as just looking on ecas website and they do a 17.2 also. :?:

2 ways top go
1 ream eye in arm out , fit oversized pin.
2 run a heavy bead of weld up the eye on the arm to shrink it , fit standard pin

all depends on which tools you have available Viking got a good pictoral guide to putting it all back.

I think (was it Russ) was right in saying by fitting an oversized pin your just delaying the problem

Yes fitting oversize pins is indeed delaying the replacement of the arm.
Sean may very well have his way reaming the hole. I would recommend not to, to keep as much meat as possible by not removing any metal. I never ream the holes. I understand that it is common practice but not on king pin replacement. The king pin is hard steel, arm soft. Pushing in an oversized pin will form the hole to the pin and give a firm grib ( interference fit )
