sounds to me like a possible track bar problem. there are several threads about the "Death Wobble" and you can goggle them if ya wish. but they all end pretty much the same way, you need to do something about the track bar.

Are the wheels towed in about an eighth of an inch?

I dunno. The alignment is supposed to be within normal specs. My father also asked about the alignment. He believes that some combinations of camber/caster could produce poor tracking - even if the overall alignment was in spec.

What is the significance of the eighth inch toe-in? If it produces unstable tracking, shouldn't one of the professional mechanics have caught it??

No - caster can be adjusted with the adjuster cams on the lower link arms. Camber is fixed, but offset sleeves for the (I believe - been a while) upper ball joints are available if needed.

My vote goes for a worn joint on the track bar, as well.... very common wear point on these trucks.

You can check the tow with a tape measure. Pick a tread on each front tire and measure both on the front and on the back of the tire. The front measurement should be about an 1/8" less.

This is how you check the tow:

I did have to check the toe one time, used a 1 x 4 board, 8 feet long.

Why did he tow you"

And the guy looked like he knew what he was doing. I don't

If it's a real strong tape it might get it rolling

Big toe or little toe, which foot?

I'm confused too many toe's,er tows.

Spellin' ain't Beekeep's forte'.

You are correct. I learned 2 things from this thread.

Hell, Mike, I even looked it up but my little dictionary didn't reference tires for either spelling so I took a guess. Maybe I should have spelled it tough but that would have been tuff.

No sweat, we knew whatcha mean't... but we never miss an opportunity to give ya' s*it.
