Hendrickson walking beams alignment

Did you readjust set screws in top plate? Have to snug up spring bolts, tighten set screws, then torque spring bolts. Bent cross tubes cause some funky issues too.

 

That should take care of it. Hendrickson always wanted whole truck jacked up and drop beams and cross tube as unit. Keeps everything free and out of a bind.

 

I had to reread this. Like spsauerland said. Also check that the center bolts through the springs fit properly in the mating hole.

 

Yes they are half inch put the point was the size of the head. They are not all the same. Does it fit in the hole and not bottom out. Are they in the hole? Are both the springs the same? Measure center pin to front bushing.

 

Like Boxcar said, it may be where the center bolt of the spring pack sits in the saddle, there is some play there, so if you tightened down the bolts with walking beams slightly pointing one way or the other, that is why it is dog tracking now.
