Shakes when I go around 100mph. Any ideas wht might cause this?

 

Your tires.

 

your tires are probably out of balance or you have a bent wheel. Could also be a out of round tire, but you would feel that at lower speeds as well as high speeds. If it's neither of those check out your front end for bad tie rods.

 

I have the same problem. but my car starts shaking arourd 65+ almost to 80mph. thats when its the worste at 80+ the shaking calms down. i dont feel anything at lower speeds though. Oh by the way my CV boots are broken could that be it. I know i know. Ill get the boots replaced as soon as i get some $$. What could hapen from driving on broken cv boots. I just barely noticed them when i changed my oil. I dont know when they broke.

 

Dont drive 100. LOL

Its everything everyone else said.

 

thanks guys!

 

same enivitable (sp?) shake happens to be between 60-80 and is fine after that.....i need to get around to getting my tires balanced, rotated, etc....hope that fixes it

 

its more than likely you CV boots....after i bought my car, i noticed that the car would shake like that so i took it into a shop....my front axels had to be rebuilt, but after i left the shop i had a nice stiff ride...now i hit like 105 without noticing i'm going that fast because its smooth

 

i had shaking around 65 mph.. got new tires (kumhos), now its smooth all the way to 140 (not that I ever go that fast)

 

I have driven with blown halfshafts many miles before replacing them. They never caused my steering wheel to shake or any vibrations.

The flat spot on my rear pass. tire I recently aquired after a brake lock-up has caused some, and I am scared the tire is off balance after a little encounter with the curb. I have severe 65-80mph shakes.
