Vibration After lift
I installed a 6" lift on my 84 F150. I believe I did everything I needed to do... installed the lift, installed exteneded brake lines,
lengthed drive shaft 1" with new universals and a balance, installed new 35x12.50x15 tires on new 10x15 rims, siped the tires and had an alignment done. NOW...here is the problem, I have a vibration starting at about 15 mph and increases in frequency and severity as speed increases. (sounds like running over the raised dots in the highway, just not as severe). The vibration is felt the worse right under my left foot through the floorboard. I can also hear the vibration when driving next to guardrails adn retaining walls, etc...
Can somebody help

Did you change to a very aggressive tire? My Swampers vibrate down the road so bad it almost puts my foot to sleep
If so then maybe try to put different tires on and see if it goes away.
Other than that probably the driveline.

I've got the same problem.
I lifted my 96 with a 6" Cepek had the shaft lengthened. Everything was ok until the lift. My vibes happen at 0to30 mph and then they dissapear. I've had guys check everything thats been suggested with no outcome. I can't firgure out whats goin on. I used new springs with factory blocks, the vibration also seems to go away when my clutch is disengaged. When power is applied is when I get my vibrations. It disapears after thrity but returns ever so slightly at about 60 mph. I didn't get any new tires. Everything was fine until the lift. Shaft is brand new and balanced.
Anything you can find out would be great. I've tried different forums everywhere with no luck. Everyone says the same thing. Angle, shaft, CV had everything checked.
