call bs on zero rust, but anyway rotors could be it but it would do it at any speed, worn steering components can do it to,

my dad said it could be the drums or the old shoes so i pulled the drums they look fine the shoes were cracked and one spot were broken so replaced did nothing but improve stopping. it feels like its comeing from the front i replaced the front shocks but if the shock is blown out would that make it happen? also would worn rear leaf springs and bad rear shocks make it shake?

Front rotors are warped. Replace pads and rotors in the front and make sure the calipers retract properly. If they do not retract smoothly, replace or rebuild them. Further, your truck has ifs, if the suspension bushings are toast, you can transmit some nasty vibrations to the chassis/body from the control arm slopping about.

I'm gonna guess that you have the t-bars cranked up, you probably have some bushings that are rotted out, like the control arm bushings. Probably just about all your suspension stuff on the front is junk, depending on how long it's been cranked up.

If it's not the brakes, then make sure your wheels are balanced right and all the lug nuts are tightened properly as well

You can't tell if the drums are out if round by eye balling them. If you feel pulsation in the brake pedal and the entire truck shakes when using the brakes replace or machine the rear drums.

yea your typing isnt helping us diagnose this at all.
so from my understanding when you hit the break it doesnt get better nor worse and its all the time during driving?

doesnt seem like its brakes, so its either front suspension or something in the rear

id jack the truck up and start checking your whole front end comonents, bushings,steering etc.

if that doesnt seem to be it check rotors just to be sure. and if that doesnt work start checking out the rear. its possible that you have a bent axle shaft but unlikely, cant say it cant happen though.

Any luck with this yet. Could possibly be a front axle shaft that has a bad joint.
