Quadrasteer shocks (or vibration cause)

[JasonH70]

I'm pretty sure I know the answer to this question based on my searches, but I thought I'd see if there were any new breakthroughs. Most of what I could find was from a few years ago.

 

From what I've found, I can either go back with factory shocks ($$) or reprogram the truck to ignore the shocks and put on some regular aftermarket shocks. When I google "quadrasteer shocks" I get a lot of results that say "excluding quadrasteer".

 

Victim is a 2003 Yukon XL 2500 4WD. I do not have the selectable ride control - there's no switch on my dash.

 

It has 180K on it and its developed a vibration in the right front. Everything seems tight in the front end and the tires have been balanced and rotated. Maybe there's something else it could be?

 

Thanks for any input!
