Front End Vibration?
I own a 77 Ford F-150 4x4, Ranger XLT, it's got a 351M under the hood. It's got a 9" in the rear, and a dana 44 in the front, just like from factory.
The problem is that I'm getting some nasty vibration from the front end. I am running 34" super swamper TSL tires and Aluminum Dick Cepek wheels. At first I thought it was because I hadn't had the tires balanced. So I brought it into a shop to have them balanced. That only made things worse. I was wondering if this could be caused from warped rotors, or loose brake pads? What other factors might contribute to the vibration?
Thanks.

My death wobble started around 45ish and if you powered through it, it would go away after 50. I think that this is fairly common too.
I had to replace the trac-bar bolt/stud along with the bushings.
However, 34s are a bit large to do a traditional balance. A lot of guys use sand in the tires instead of the weights along the rim.
Do you have a lot of slop in your steering wheel? A worn pitman arm ball joint or other components in the box could be magnified by the lift and tires.

If you have a king-pin style front end, you might check the bushings.
The easiest thing in general is to jack the truck up and lay under it while your buddy dorks around wiggling the tires and steering wheel. And serious problems will present themselves pretty fast.

Warped rotors are typically only noticable when you are actually braking. The truck will seem to "pulse" while you're slowing down. It is very apparent by feel on the pedal.
