Can someone define the difference between a suspension wobble and a driveline vibe? Just added 2" to an rc 3" lift. Now have a shake that starts about 50 mph through 60 mph. Shakes everything enough to make it difficult to tell. Re-rotated tires back to original positions, have checked all front end components and all are tight. Front axle is only 1/8" off to drivers side, will have adjustable trackbar with bracket tomorrow. Only thing not changed is the upper control arms. Lowers are iron man adjusted to 16 5/8" (was driven before adjusting from the 3" and it didn't change the shake). Does have a 1" tc drop. Thinking about increasing that to 1.5 or 2 just to isolate it. Rear has shims and shackles so angles should be good without binding. What am I missing. Do I need upper control arms? By the chart here They would only be 1/4" longer so the caster angle should really make no difference.

I have quite a bit of experience with tire and suspension problems and have always been able to tell what the problem is pretty quickly. This one I can't isolate.

 

nevermind everyone. Got it figured out.

 

What was it?

 

yeah man, what was it cause i have a similar shake/vibe but i'm at stock ride height.
