Hi all!

I'm ready to replace the front wheel bearings and wonder about the condition of the KIngpin ones.

Is there a way to get an idea without removing them, which means taking the axle out and completely dismantle the front hubs, knuckles and all?

With everything fully assembled jack the front wheel off the floor. Grasp the wheel/tire assembly at the top and bottom and try to rock it in and out. Moves more than an inch inspect and replace as needed the bearings.



Check preload, if king pins display no turning resistance preload is way off and requires dis-assembly and inspection.



In addition to your manuals there are many other good references:

You still have to remove them and inspect and lubricate them. Do not rely on not seeing there. Even tight bearings can be pitted. Why would you not want to inspect everything?

Good point. If you follow the lube chart regimen every 12,000 miles or annually, whichever comes first, you are expected to inspect, clean and repack wheel bearings and inspect, clean & repack kingpin bearings. Note 6 recommends this.

Are you working on wheel bearings for a problem or has this point in your lube schedule arrived?

Also keep in mind that any water that gets into the front axle will eventually settle around the lower kingpin bearing and will actually float the grease away and rust the cup and cone. If you have never physically inspected the kingpin bearings, now is the time (and each year hereafter).
