i first thought it was the rotors, i just replaced them and i have a slight vibration coming from the rear of the car. i know its the rear because my steering wheel doesn't shake.

any ideas?

Tires could be imbalanced or worn unevenly. It could be a camber or bushing issue as well, but I'd start with the tires.

DIYMIKE

i just replaced the rims i had on the car with balanced ones....

still vibrates..

But i think i might know why it shakes

When i built the car, the front end was on Jack stand. and the rear was not... and the back end was just on rear tires.

i read that its a big no no.... what could be the problem? from have the rear suspension like that.

i dont think that has anything to with anything.

vibrates during braking? certain speed? rpm?

lugnuts are tightened? i mean really, check it again. take the wheels off and on.

thats a new one to me and makes absolutely no sense

It could be the hatch. Mine sqeaks under hard cornering/braking. Vibrates only at idle. It could even be your jack stand.

Did you replace the suspension?

I did that on my ef and i still have exhaust rub on the lower control arm which echoes throughout the car.

DIYMIKE

well i read post here on HT that you shouldn't have load on the rear suspension because it wears out the rubber bushing more quickly. i had it jacked up for more then 5 months.

any way, there is vibration coming from the REAR.

the strange thing is that i CAN NOT feel it in the Steering wheel, which leads me to believe its in the rear.

i just changed my Front rotors and My steering wheel still shakes when i slow apply the brake. but if i am cruising and get to about 40-50 and put it in neutral... there is vibration that you can feel throughout the car. BUT Not in the steering wheel.

I have aluminum racing lugnuts, that i torqued with a torque wrench. i put two sets of rims on that both have been balanced.

does that make any sense?

what could it be? or what should i replace?

FYI: You should NEVER store you car on jack stands. The bushings are meant to stay fully loaded with the car on the ground. When you put the car on jack-stands, the suspension goes into the droop position. When the suspension droops, this twists the bushings out of their rested state. If the bushings are left twisted for an extended period of time, the rubber will quickly deteriorate (like holding a rubber-band in the stretched position)...</TD></TR></TABLE>

here is where i read it at.... in an old post.

Tyson

94eg exaggerates. its preferable to store the car on jackstands under the suspension, but i wouldnt make a big deal about it, and it almost certainly has nothing to do with your vibration.

hows your shocks? are you dumped?

SIred91

Hub assembly? maybe worn trailing arm bushings, tires out of round? rear needs an alignment?

DIYMIKE

i have adjustable KYB's with H&R springs. Not dumped at all. i am actually thinking about lowering it more.

i have integra rear trailing arms. the bushings are gone of course....

- the driver side rear caliper is seized and does not do anything. only the passager side works.

ALSO i don't know if this makes a difference.

i have a 4040 prop valve. i DID NOT bleed the rear brakes. i only bleed the fronts.


i have jacked up the rear and front of the cars with the tires off and shaked the control arms and sway bars and nothing is loose.

where should i start?

And you wonder why there is a vibration?

boosted91crx

I once had a massive shaking and vibrating from the rear of my car, felt like the car was gonna fall apart, so i pulled over and started checking around and what i found was my old lady had left her vibrator in my trunk and it had switched on, check to see if she left one in your car to ... sorry I couldnt resist.

the caliper spins freely.

and i have driven many ef's with old ripped trailing arm bushings and never encountered shaking like this. what are the symptoms of a old trailing arm bushing?

Tyson

i dont think it has anything to do with your ripped trailing arm bushing either.

im going with shocks.

az90civic

wheel hub? my car was vibrating pretty bad from the rear as well and i changed out the wheel hub and that took care of it.

Tyson

if it is the bearing/hub, then you should jack the corner, and turn the wheel. youll know if the bearing needs replacement.

it would kind of make sense as to being related to the seized caliper. it probably at one time heated up the rotor as it was constantly braking and cooked the wheel bearing.

i didnt think the bearing would be the problem as i didnt think it would cause vibration, any sooner than it would be obviously audible sound of trouble. but the above poster said he experienced it, i wouldnt be surprised.

DIYMIKE

thanks for the tyson, as well as every one else.

i am going to work on it today to find out the problem and post pictures.
