They re-centered the steering wheel and checked again everything on the front end - at least they confirmed again that I have no damaged components on the front end :lol:
So, what the heck - I gave them another 3 bills to replace the steering shaft. They said the one I have on my truck (long and thin) has been known to cause problems. And I have been wanting to replace that sucker for a long time because it was so flimsy and had some freeplay. The steering feels much tighter now, but the truck is still not perfect. The drift in the direction of the crown remains (pulls to the right in the curb lane; to the left - in the hammer lane).
2 possibilities still remain: (1) try to adjust the CASTER more and (2) switch to the original tires that came on the truck from the factory (295 low profile).
Thanks to everyone for the comments!
What is the current caster angle ? |

| Generally the more caster the more stable the truck is. Going to shorter tires would would lower the front of the truck thereby decreasing caster. So I would stay with the current tires You can get more caster put in but you might find your tires getting some irregular wear on the the outer edges because the wheel will lean into the turn a hair when you crank the wheel over hard thereby loading up the outside edge of the tire. I think you'd be better off to borrow one of MacKinnons company trucks to see if this isn't just an Int thing before throwing more money at your truck. |

Okay, here's how the story ends. If someone runs into problems with steering, take note: the biggest improvement I got was from switching to low profile tires - the original size the truck came with.
I now have Yokohama 295/75/R22.5 on the drives, and Michelin 275/80/R22.5 on the steers (our tire guy said Michelin didn't make 295 tires!). The truck steers way way way better. The fact that the steers are pumped up to 110 psi might be helping a bit too. |
