ahhh...the dreaded death wobble...drop down kit was the reason on my '92, and it shook so bad that I had to replace most of the rivets in the front half of the frame with bolts because they were so beat out. tie-rod end slop, inadequate caster, loose or crappy lift/ bracketry, way out of balance tires, worn bushings, shot kingpins or ball joints, and deflection of any kind. Pick any two and it = death wobble. Only thing scarier than driving in a truck with DW is seeing one with it coming at you... I tightened up everything I could and mine went away.

Check for a blown shock. Remove the shock and cycle it a few times. Regardless of the type of shock there should be resistance when attempting to compress or extend it.

Check caster too. Might not have enough positive caster.

NO WELDS. ALCOAS...Yep, it is the death wopple that is for damn sure. So besides tighning everything, should I rip the kit out? I believe that drop kit was so popular because there is not alot to choose from out there.

On a TTB replace the I beam bushings, this is always the first thing to do to cure the dreaded "death wobble". This is if there are no obviously broken, bent or missing parts in your front end.
This problem is caused when there is not enough resistance to the side to side movement of the axle. On a straight axle you would first replace the panard rod bushing as it keeps the axle located from side to side, on a ttb truck you replace the I beam pivot bushing. The violent side to side jerking of the steering wheel would make you believe that the whole front end of the truck is going to fall off, but replacing the bushing will solve this problem 95% of the time. Napa has the TTB pivot busings for around 23$ each. Good luck.

TTB is 4wd but I think he meant I-beam. 1997 F250HD was I-beam, but there was
also an F250 A-arm based on the new F150 that came out in 1997. Both just say
F250 on the side. The 1997 F250 I-beam truck is more common than the F250 A-arm.
