The right side is perfect. The ball bearings looked fine. Any ideas? | | | | | Joined: Feb 2001 Posts: 1,096 'Bolter | | 'Bolter Joined: Feb 2001 Posts: 1,096 | Two things to look at ,
Axle eye end slogged out , it will need machining and a bushing fitted .
or ,
Outer wheel bearing , inner race not a snug fit on the end of the spindle , need to change the spindle .
I just found this defect on my '40 , wondered why the bearing moved when it was correctly adjusted ! Had to fossic round for another spindle that was not worn at the small end . | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | If the kingpin hole in the axle is "wallowed out", another option is to ream the hole (eye) for an oversized kingpin (if the hole is not oversized by more than 0.010").
Another cause of looseness is that many steering knuckles have "wallowed out" kingpin bushing seats (I am not sure of my terms here). New king pin bushings then move around and the joint is loose (as described by John). Some people have luck knurling the bushings and pressing them into the seats in the spindle - I have never had luck with this. I am not sure if the bushing seats can be drilled for larger bushings (larger outer-diameter).
