Bad Vibrations!!

[justin's_94]

I have a 92 Bronco that I just installed a lift on today. I used 2" coils in front and 2" block in the rear. I did the coils a week before the rear blocks and it rode fine. But today when I did the blocks in the rear, I am getting some bad shaking/vibrations when I drive the vehicle. Before I installed the blocks, I had factory blocks in the rear that were tapered to the front. I removed those when I installed the new flat 2" blocks. I do not know if i messed up by removing that tapered block or what, but I need some help. Did I give the truck a bad pinion angle or something. I know that this is not an explorer, but there has to be some kind of suspension guru out there that can help me.

By removing the stock blocks you have altered the pinnion angle enough to cause the vibration. If it were me, I'd put the stock blocks back in and use an add-a-leaf to lift the rear.It may ride a little worse, but you wont have the driveline angle problems.
