    The original kingpins are worn out. I knew this day was coming. Have it in a shop to get the job done. Not something I think I could set up right even if I did manage to get the old pins out. How many miles did you guys get out of your kingpins? I've heard of people replacing them around 700,000 miles. As a habit I have always jacked the front end off the ground when greasing them every 6,000 miles. I think they take grease better when suspended in a free state like that but I could be wrong - have actually been told that was bogus but who can argue with 1.2 million miles right? Not a big deal to jack the front up on pm's.

    I've also heard that. Never done it but heard it. There were some rare times when I was in a rush to finish a pm and said to heck with it never lifting the front off the ground, but that wasn't often.

    I've got 1,079,790 miles on mine and as of last weekend absolutely no play in them. I grease this truck constantly. Grease is cheap. Tho I don't jack it up. I've heard both sides but the guy I trust more on suspension things said it wasn't needed, and while wouldn't hurt is completely unnecessary.

    Sold my W9, in December, it had 1.3 million on it, king pins were still the originals. It has to have close to 1.4 million on it now, still have not been changed. I never jacked the front up to grease it either.

    The guy who bought it from me also has a T6 with somewhere around 1.6 million, he has replaced the kingpins in it 3 or 4 times now.

    I maybe shouldn't confess this but if I get 500,000 out of a set of kingpins I am lucky. This is on W9s. I firmly believe jacking up the front end should help to prolong their life. Grease with the truck down. Then jack it up and grease again. Where did those last 2 shots of grease go before you began to see it coming out. Why don't my king pins last longer? I wish I knew. I can say that until Nov. 2013 I could not find anyone who knew how to line up a W9. I love W9s but I have bought way too many steer tires and king pins. Maybe this last alignment will help that. I should add that most (90%) of my work is short haul.

    Kingpins are done. Alignment also. Rear axles were off slightly but true now. Have a slight issue though. Truck feels a tad squirrelly now. It will run true but making lane changes it almost has a bump steer feel to it. It feels like a slight rightward or leftward motion on the wheel like it gets "stuck" wanting to veer that way. Sort of like the steering is either too tight or too loose which it's not. I can go to the right and it will want to veer that way afterwards until I correct. Doesn't take much to over correct then it wants to veer left. Could there be a problem with the installation? Or is my steering too tight maybe? Like I said, it tracks true once you get there. But any lane changes causes the squirelliness and bump steer feel again.
