THE DEATH SHAKE
When driving my truck as soon as i get over 25mph it gets a insane shake that is so bad i feel like the windshield is going to blow out. My truck has been lifted and it has 36" tires. I feel like its the front left tires. My tires have been balanced and are at the right air pressure. HELP

Did this start after the 35's were put on? Maybe swap that tire with the right rear and see if the shaking goes away up front. If so, you may have gotten a bad tire, seen it before. Also, make sure everything is tight up front, tie rod ends, wheel bearings, lug nuts, all bolts for lift kit, etc..

Do these trucks have a track bar on the front end? I have a 95 F SD that was having a death shake over 45 mph. It would try to take the steering wheel away from you. I threw everything at it -tie rod ends(inside and out), wheel bearings, tires. It turned out to be a track bar. It had a little rubber grommet in it like a pivot arm bushing does. I replaced it and the death shake went away.
Sometimes the steel belts can seperate on a tire and cause a wobble. The few I have experienced didnt shake like your saying though.
Those big mudders you have might not even have belts in them either.

these trucks come with twin beam front ends which do not come with trac bars because each side is attached to the frame unless he has put a solid axle front end like mine

Problems with the TTB arise at around a 4'' suspension lift. Sometimes you might get away with it, other times not. The 4'' lift kits I see comes with new radius arm drop brackets and a drop pitman arm.
And, since the PO has 35's, that's why I'm leaning towards alignment.

well if it ends up NOT bein a brake caliper i would strongly suggest puttin a solid axle dana 44 under it instead of pouring $ into a axle thats known for eating tires and not staying aligned. it will save $ in the long run.

I couldnt recall if the TTB's used a track bar or not. I know the TTB's are finicky about lift kits. The guys that build the pre runners have to cut and weld TTB to get the angle back to right for the ball joints when they lift them. I didnt know 4" would screw something up like that too.
The F Superduty I have is 4x2 so it has a different set up all together than the 4x4's and the other 4x4 1/2 ton I had was a Dodge and it did have a track bar also. Like you said though it was a solid axle up front.
Barkin 40's , did you do a SAS or did your truck come like that?

ive done a sas before but not on the blue ford, it came like that but its not done as well as i would like it to be, its fairly easy to do if you get all the parts together at one time and get it done in one weekend day dawn to dusk, you dont have to have a welder but i would suggest to weld rather than bolt, but thats just me

All 1/2 ton Ford 4x4's come with the TTb I was thinking. The 3/4 tons can either have the TTb or the SA , but the 1 tons and bigger all have SA's . Did Ford ever put SA's in their 1/2 tons like even many yrs ago?

1980 was the first year for the ttb, prior to that they used straight axles. 1985.5 was when Ford brought back the D60 in F350's, prior to that ALL 1980-85 4x4s came factory with ttb.

For a stock daily driver or even a modified 4x4 trail rig, the TTB does just fine in 1/2 and 3/4 ton vehicles. The issues come from not being able to get the alignment right. To fix this, use the proper pitman arm, proper radius arm drop brackets and/or longer radius arms, and if need be, having new camber and caster bushings installed on the drivers side of the TTB like dohc_chump mentioned.
For most daily drivers and mild offroad use like for going hunting or added security during hard winters and maybe even a little farm use, the TTB front end is one of Ford's smarter ideas. I personally love the ride quality that they give.
There are also plenty of articles online about making long-travel TTB suspensions. Not to mention the guys who like to build pre-runners love them. There's also a decent amount of aftermarket support.
