Question about 2007 GMC Sierra 3500HD
Allways been bad U-Joints, or a bent drive shaft that has caused the drive shaft to vibrate between such speeds.
Does it shake when accelerating hard up to 50mph? If you aren't getting any shaking in the steering wheel, and it feels like it is coming from the front, then it sounds like bad axles (mainly bad inner CV joints).
Try rotating the tires back to how they were before the shaking started, and see if it changes (not likely if there's no shaking in the steering wheel). Check this fault in two sample video:
Another thing, check all the suspension bolts you undid to change the coilovers. Make sure everything is tight. Did you neutralize all your suspension bushings before tightening the bolts? If not you could be getting bushing bind. To neutralize suspension bushings: loosen the suspension bolts, load the suspension (either the car sitting on the ground or the jack stands holding the car up by the suspension not the lift points), tighten the suspension bolts.
