Highway Speed Shakes

Hi y’all,

I’m trying to figure out where a shake is coming from or what it could possibly be… I have been experiencing a shake at highway speeds anywhere from 50+ MPH the shake is mostly felt in the steering wheel but the whole car kind of shakes. I had my front tires balanced and also replaced my whole driveshaft assembly. I’m wondering whether it’s tires or suspension system, i’ve done the shake test on the front wheels and didn’t really solve much for me. If there is anything that I could try or test that would be great!

 

welcome, were the tires road force balanced ?

 

Try rotating rears to front.
Sometimes tech doing balance does it poorly.
Old weights removed first. Spot on inside of wheel must be cleaned for weights to stick. Weight cannot get dirt on it before stuck to wheel.
Rarely a wheel tosses a weight off (due to poor attachment).

 

So I rotated tires front to back and I am still feeling the shake??? Help this shake is killing me, it seems my alignment is a little bit off but I dont think it would cause this severe of a shake.

 

Welcome

 

Welcome from Wisconsin! Alignment, then get the tires road force balanced, you might have a bad tire(out of round, ply separation) a tire tech with a bunch of experience should be able to sort this out, maybe a bad wheel also, mud stuck on the inside of a wheel. Good luck
