Mild Thunder Posted October 14, 2009 Share Posted October 14, 2009 Hello, Im new here. I have a 1998 CH, and my drivers side steer tire is wearing badly on the inside. Outside is fine, along with passenger side tire showing no abnormal wear. A buddy told me its probably just a "kingpin" bearing, and its a easy fix. Something about dropping the lower nut, and just putting a new bearing in and retorquing? Can it be that easy of a fix?? Steering does seem to pull a little to the right. Truck is used off road quite a bit and potholes are ridculous around here. Thanks!!!

tech_j Posted October 14, 2009 Share Posted October 14, 2009 Use a long bar and shake the wheel up and down. If you have a ridiculous amount of play, it is possible the kingpin/bearing could be at fault. If not, it may just need tires and an alignment. First I would recommend trying to tighten the cap. Simply remove the cotter key and tighten clockwise to the next slot. If not, you'll have to remove the cap and inspect the bearing. If it is not crushed, then the bearing is not at fault, and you'll need a set of pins/bushings. Quote Torque wrench? Can I put an air hose on it??

Mild Thunder Posted October 15, 2009 Author Share Posted October 15, 2009 Went to mack dealer tonight, to get the kingpin bearing, and parts guy says I have a bushing, not bearing, as its a meritor/rockwell axle. So could the bushing be worn? Quote Link to comment https://www.bigmacktrucks.com/topic/11046-kingpin-issue/#findComment-41954 Share on other sites More sharing options...
tech_j Posted October 15, 2009 Share Posted October 15, 2009 (edited) Yeah sorry, totally assumed you had a Mack axle. He is correct, Rockwells (nor Spicers) do not use the bottom bearing. It is possible you have a worn bushing... Have you shaken the wheel to see how much endplay you have? Anything 1/8" or less, I would be looking for another cause of the wear.
