after 1,228,197 miles

Did they measure the holes in the spindle before they installed the bushings? The spindle can "egg" out after a million miles or so.

I replaced the steer axle at 1.3 million for this problem. It was cheaper to get a reworked axle than replace the spindles, since the shifting kingpin bushings wobbled the spindles...which screwed up the ball joints and the steering seemed to catch sometimes and be too loose at others.

And you can bet the the spindle holes will be MICRed every time the kingpins are replaced. It was only off by a few thousandth, but it doesn't take much.

 

It was Nacarato Nashville that missed it on mine.

The guy that normally works on it was out sick for the season. He works on pit and logging trucks so he's seen it before. Drop 80k in a trailer and the tractor wears quick. He knew what was going on when I started complaining. Convincing Nacarato was another problem.

 

1.1 million miles on my T800. I'm sure they are on their last legs. Bought this truck used in 2007....IIRC it had 800,000 on it then. Not sure if they were done before we got it but I doubt it.

 

Always greased the bottom ones first . With the truck sitting on the tires , you hit it with a good grease gun you will see the truck raise up .

 

If the holes for the pins in the axle are out of round I would think that the truck would just wonder all over the place, you would never be able to keep it in a straight line. I wonder if maybe they something a little to "true."

Mine started feeling tight and had to give a bit extra bump to make it start or straighten out was the steering wheel ujoints bottom set got wore out even though looked good and greased. Replaced both top and bottom and steers like a charm again

 

mine are presently "out of round" and was told by the guys who replaced them that they would last about a year or two before needing replacement again

figured i would have the situation properly corrected this winter

but it drives straight, without a wobble
