vibration while excelerating - Tuner-Junction

Johnlude85 · #1 (**permalink**) April 22nd, 2006, 10:43 PM

i got a 4th gen lude with an h22. when i get on it real hard, the whole car vibrates but its not really all that noticable. kinda strange. its not brakes, its not a bent wheel or something. i was wondering if anyone has ever had a problem like this. i was suspecting maybe motor mounts? im not sure though. theyre kind of expensive just to see if they fix a problem or not. i guess if they dont though, i can rule that out and ill have new mounts. but yeah, balance shaft is functional, brakes arent warped and its not a bent wheel. anyone have a clue?

thanks in advance guys.

nope, i rotated and balanced the tires at work not even a month ago...the same time i did the alignment so its neither one of those.

it feels like more of a mechanical, or power vibration then a suspension/rim and tire vibration. it only does it when im on it real hard after 3000 rpm.

hmm, like you said, check engine mount, loose sway bar, blown struts..loose bolt somewhere...

or could it be your muffler mounts?[rubber mounts]

or uh..ehmmmmm

that's as far as my car knowledge goes..

i have a tiny little ding, kind of a dent in my crank pulley. think that could be the problem? i dont wanna spend $200+ on something that onlu MIGHT be the problem ya know?

put your car on the lift and run your engine, and see if all your pullies spin right if that's the case.

other then that..
loose bolt, broken mount, un-circular disc's spinning..

hey, what about a shitty ebay cone filter on my cai...would that cause a vibration "feel"? just a thought. im hoping its not the crank pulley. that would kinda suck. i dont feel like changine that lol.

if it was an intake that was rattling, you'd hear just loud ass rattling, not actual "feel" of vibration.

but if it was crank pulley, you'd know the feeling all the time under normal city accleration

it could be the axels too, happened to my buddys dsm, if thats the case, pull off the left and right wheels, stick yuor finger behind the main rubber seal and feel if its ripped, if its sweating grease tu necisitas nuevos axels (spanish for you need new axels)

the axles are brand new from when i did the swap a few months ago. i ordered reman from autozone and they messed up and sent me brand new. so i got new axles for 60 bucks a piece.

you're talking about CV (constant velocity) joints. you'll only notice a clicking from that when turning, more so if it's a tight turn.

my money is on motor mount, but it could be so many things. is it during acceleration (does it stop when you level off at speed), or is it all the time above 3K?

its only when im at full throttle, or verry cclose to it. it does go away when i let off. thats how i konw its not a tire/wheel/suspension flaw. however, it does not happen all the time. like for instance, the story is a little off topic but it sorta relates. i had a cold air intake with the filter in the front bumper. well i got sick of my heart stopping everytime i hit a puddle so i just now (not even an hour ago) cut it so that it fits under the hood. i took it for a test drive and got on it. the intake is alot louder when its closer to the tb btw, sounds nice as hell. but it didnt do it then. it only sometimes does it. i cant figure it out. im good when it comes to cars, thats what i do for a living. im suer ill figure it out eventually. i just needed my fellow enthusiasts help in trying to find it sooner

I'm thinking axles too. My CRX has a vibration when accelerating right now. I got under there to look and my Right axle's inner boot is oozing grease. I think either the axles is bad or not balanced correctly.

...thanks once again HASPORT

liek i said already, my axles dont even have 5000 miles on them, i bought em braand new, not reman. the boots are fine. i actually wish it was an axle because atleast id know what it is, and i can do a lude axle in about 30 minutes.

uuh...did you see my car dude.... everything on it is brand new including my axles and they are screwed. Parts can be messed up even know they are brand new. Axles after being manufactured need to be balanced on a special machine. They may have screwed up. Not saying that's your issue but it's a strong possibility.

yeah? is there a way to tell for sure, or would i need to get more new axles and try em out? that would suck to spend that money and still have the problem ya know? i didnt know that new axles could be screwed up from the factory.

A driveshaft shop can tell you while you wait. The charge probably wouldn't be that bad either. When I worked for Honda we saw bad axles every now and then. It is rare..... but it does happen. RWD cars have driveshaft balance problems all the time, and it gives the same wierd vibration.

i doubt it, though. if it were that, you'd have the vibrations steadily increase from idle to WOT. since it's only at WOT, it's probably something else.

Probably right, my vibration is only at slight throttle angles. At WOT it is not noticable (then again, I can't notice much of anything during WOT runs).

which boot is it? the one off the tranny, or the one going to the wheel?
