when was the last time one of those large 4x4's was doing 80+ on the freeway. /QUOTE]

This morning on the freeway.

I have a longer response, but I'm on my way out the door for the weekend. I think we agree on most points but our terminology is different.

my point is, what is acceptable to them, should be different than what is acceptable to our cars. vibration out of a huge truck is common and therefore it is looked past.

it all comes down to a few things;

is it stock? if it is in all aspects including ride height, dont even think twice. set the pinion to the tranny and call it a day. gm wouldnt have designed it not to work (well maybe, it depends on what kind of day they were having).

is it something other than stock? do you have a longer tranny, a different rearend which puts the pinion at a different height, a lowered ride height, etc...??? if you do i would measure the ds at the same time. it only takes a few extra minutes, and instead of just making the angles the same, you could set up the working angles perfect.
