Just recently the front suspension on my 92 si civic shakes when i get to 60 and keeps shaking until 80 ONLY UNDER ACCELERATION. If I coast the car into these speeds its fine. OK I balanced the tires, still shakes. I looked at my lower control arm bushings and the one where the shock fork bolts on to is torn. What else could cause this? I did a search and from the search I now decided to go with either Mugen of stock bushings.

Also the rear end of my hatch makes a knocking noise from the suspension? When I go over bumps the rear shimmers not just goes over firm and I HATE THAT. I have brand new Bilstein shocks with Nuespeed Race springs on all 4's. Also the front knuckle is a 97 GS-R.

Thanks for the help.


CHANGED AXLE AND STILL DID NOT WORK. PLEASE READ MY LAST POST.

I have the same problem on my EG SI . I was thinking motor or tranny mount , and/or the tie-rods . If you figure it out let me know ! Good Luck !

 

check your tires, mine would do something similar to that and i had bald tires after i replaced those never had problem also make sure one of the wheels isn't bent

I've got brand new potenza's on mine . But he is right . A little off round and it will throw your whole **** off .

 

Damn people... 90% of the time vibration/shaking on acceleration is a bad axle!

Replace the axle on that side.

 

Both my axles are brand new . So I know thats not my problem .

Just because they are brand new, doesn't mean they are perfect. Where did you get them from?

I can't remember there name. Thats where all the work was done on it when he owned it . I had thought that myself , until I saw the reciepts .

 

I had the same problem while taking a road trip. Brought my wheels to get balanced and they were a "little" out of round. They balanced out fine but I still get a VERY small shake at high speeds. (Def less than b4, but still felt in the seat of your pants)

You may want to check your wheels if theyre "out of round". You couldnt tell my wheels were like this standing still, it was only noticable when I slapped them on the balancing machine.

 

what gear? try it in 4th and 5th and see if it make a difference, maybe the gear is mess up in 5th.

 

yep i sure check the axle...

 

if i bet anything its one or more of your mounts. not your tires or axles.
think about it, your driving, and during acceleration your engine is moving, w/ broken mounts there is going to be a vibration. when you idle or coast(like when you pop into neutral) the engine isn't really moving(atleast not enough to feel) theres no vibration. if i was you i would check all your mounts and replace them.

 

It is most of the time axles.
I tried 3 sets of tires before i finally gave in.
the big killer, was when i redlined one day, my car started smoking.
it seems that the axle grease leanded on my header, lol, i thought i wired something wrong and my car caught on fire
lol

 

I have the same problem with my eg when i hit 100. Its because of bent stock steelies. Same problem with my last eg at around 80mph with bent crx si's. Just my luck, i've decided to buy new rims only for now on... lol

 

do you have the right tire pressure in your tires cause if not it could throw it off the mounts if there is one that doesnt have all the bolts tight check the AC mount and the tranny mount in the front and the axles just cause there new doesnt mean anything check them just to be sure there could be one that was bad when it was bought

 

still it could be you axles i bought a set of re man. axles and i had th same prob bob....

 

Make sure your lug nuts are tightened.

 

Thanks guys I'm going to change my left side axle. I thought about it (and also read the posts). Just remembered I changed my tranny and when i was taking the left side axle out it slipped out of the joint and I PUT IT BACK TOGETHER MY SELF and sealed it with some zip ties. Plus sometimes when I hit a pot hole the car will not vibrate then when i hit another one it will...LOL

Thanks for the help guys..
How about the noises in the rear??

 

BACK TO THE TOP. I changed the axle and it did not stop. Then I said F it. I ran First to redline and powershifted into 2nd. The vibration got crazy now. there is now a knocking noise when i am stepping on the brakes. Also there is all sorts of knocking noises coming from the car like if a mount is bad or even a bad tranny. I put the car up on jack stands and put it in gear, seems fine no noises 1,2,3,4 then 5 makes all sorts of knocking noises. One guy said it is because thats the same thing as taking off from a stand still in 5th. Ummm I don't thing so. I then spin the right front rotor and it spins free. Try the left and it is very tight. could a sticking caliper cause all the deceleration noises and also the car to shim. Going to change the caliper tomorrow to see. whats the price of a caliper. 94 & up INtegra.

 

SOMEONE!!??

 

dude, check your mounts!
