Hey All,
For you suspension guru's out here... I have a 2" lift on my ZR2.
Wasn't until the temps drops and the lakes froze over and started using AWD and 4Hi mode that I noticed that the front end of the truck wobbles pretty seriously when the front end is unloaded (hard acceleration or towing/hauling heavy loads).
Called a local suspension shop and they said it's a "known GM issue" and to just not use Auto mode.
Feels a lot like the knobby tires are hitting the firewall and everything starts to vibrate / wobble, increasing with intensity the more the front end unloads.
Any thoughts on what to look into? Truck also has extended axles which I wonder if that has something to do with it.
