Whats up AZ, so for about a month now my car has been vibrating on high speeds meaning on the highway after 75mph it would vibrate hard and it got annoying so recently i went to get it aligned so they checked the front end for any issues and my passenger outter and inner tie rods were done so i got them replaced and finally got the car aligned. After the alighment i jumped on the highway and the vibration has reduced from how it was before but its still vibrating at 75mph and over. What else can be cuasing this vibration at high speed ? Anyone that had or has this prob can please tell me what you did to solve it or what you may think it is. Thanks i appreciate the help.

 

Alignment isn't the cause of wheel vibration. Look for a Hunter Road Force machine in your area and have the wheels balanced and checked for any out of spec conditions:

You didn't say but vibration from the front or felt from the seat? Steering wheel is front out of balance, seat is rear tires out.

 

Check your control arm bushings. These fail after 60k or so. Not sometimes, but always. It's a known design flaw that Acura has refused to address. Turn the wheel, jack the car up on the side turned in, and raise the car. You'll be able to see the bushing in its free state.

 

What Turbonut said...

 

first check
control arm bushings. common problem mine is vibrating at 80mpg also and I have bad bushings im replacing now.

then check all the ball joints bushing under the car and suspension areas. easy to check visually and physically with big pry bar. if anything is loose its probably bad.

after that get the wheels checked for balance

 

most likely you have bend in your wheel...even alittle bend can cause it to shake. take it to tire shop and have it balanced and see if its wobbling...if the rim is okay then mess with your suspension

 

from the front sir. its mostly on the steering wheel not so much the seats anymore after I replaced the inner and outter tie rods
I pulled out both lower control arms from the front and replaced the bushings both when I replace the tie rods so that's done with aswell
I think it might be one of my wheels that is bent somewhere, ofcourse when my girl takes my car idk how many potholes she runs into
yea im going to have to have my wheels checked out to see if they bent or not then ill see my next step after that

 

thanks guys I appreciate ya'll

 

Have you ever got in accident? If you do you need to replace the front sub-fame

 

that's related to tires, mostly front, check tire balance and wear

 

Axles? Are you lowered any?

I just had my axles replaced and it cured the 20 mph shudder I had and it no longer vibrates at 55 like it used to.

 

I heck your wheels..warped wheels will do what you describe.

 

His g/f drives the car too. If she drives like my wife.
It's going to be a bent rim.
