07 colorado 2wd 72k miles. Installed rear leaf springs and shackles last night to net approx. 2" of lift. Long story short i had to do the leafs because some of the bushings were seized.
Today I have a faint but consistent vibration when going through the gears from 20-35 mph.
Also, when I got in on the highway it made a loud, higher frequency vibration around 80 mph when I was on the gas, and it would become faint when I let off the gas. It ould do it intermittently. When I got to work I took a brief look underneath and didnt see anything awry.
I didn't run into anything strange during the install, everything seemed to go together fine.
Anyone have any ideas?
