Default Re: Front Axle - Repair old or look for replacement?

Concerning how the kingpin holes can get enlarged: It can start to happen after kingpin spindle jobs when the taper pin is inserted and tightened with a wrench instead of hammered in and then tightened. This can cause a loose fit between the kingpin and axle. After a while the kingpin will rock in the vertical plane and any space will only get worse. The taper pin should be retightened after the car is driven a few hundred miles. A lot of axles have endured a lot of abuse over the years. Probably one of the worst cases happens when the front spring sags and the shackles rest on the axle. Can you imagine the pounding out on the end of the axle. Not to mention the roads back in the day!
