well im hoping this section will produce answers for me. i have a chevy blazer xtreme its bagged with 20s KP 4 link. normal driving is fine but above 40mph my steering wheel vibrates BAD my arm shakes like crazy and you can feel the whole blazer shaking and you can see the dash vibrating. also over 55 or under hard acceloration in the 50mph range my blaze will wobble side to side and i meen bad to the point where unless im at full lift my bumpers start hitting the ground left to right. when i bring the front all the way up and slow down it will help but i just dont feel safe driving like this. what should i look for what could be causing this? i got an allignment awhile back and havint done anything to the suspension sence. any help would be great!!!

it could be a bunch of things. bad wheel bearing(s), a cracked or misaligned bearing race(s), bad balljoint(s), bad tie rod link end(s), loose bolts or nuts, loose hub nut...the list could go on & on. i've even seen a warped brake rotor do that even if the pedal wasn't depressed. also a cracked caliper piston could do that. hell even an out of balance wheel...

i'd jack it up & shake the wheel & look for loose hardware &/or defective parts.

hopefully you get someone else that will chime in that's seen this before to this degree. although i've seen all of the above cause front end vibration, i've never seen or heard of any of them shaking the vehicle THAT violently! good luck man & BE SAFE!

Can you lift the truck to where you are experiencing these problems and post a picture of the rear suspension at that height?

Put it on jacks and freely spin the tires and see if you get any type of vibration. Id start there first
