read all the threads on this. has there ever been a definitive solution? also i believe my front struts are going out after reading those threads. they were like that before the spring install. is my dealer going to give me **** about the springs if i have them look at it?


***edit***
after some more riding. the vib is really only bothering me in 5th gear. after some hard runs it doesnt vib when accelerating hard or turning etc. just when i put it over into 5th the steering wheel has this left to right vibration and the gas pedal has a slight vib to it as well. the steering wheel feels about like a sitting in a diesel truck when its idling rough. rolling down the street with the car off was smooth as silk. its also very smooth in neutral but low rpm acceleration in 5th yuck. sucks cause thats where i spend most of my driving.

and it did not do this before the spring install i swear. ops:

as for the bleeding struts. how long do i have before it goes out completely if its bleeding like that?

 

Check out this thread, hopefully this will help you:

damn if thats the case its going to be a pain in the ass for me to fix. tho it seems after settling overnight most of the vibrations have gone away. either that or i just got use to them.

 

Even though we did the install right, I still get vibes like a beotch in 4th and 5th at really low rpms. But that is my mounts (Solid engine, tranny, control arm bushings) more than anything. Try to keep the rpms at 1.5k or higher in 4th and 5th and see if the vibes go away.

 

they are still there. i guess i need to try this fix in that link. wish i would have known that going in to the install. didnt do enough research. problem is i dont know when ill ever get around to having time to do it. is it going to hurt anything riding around with it vibrating?

 

yeah...the vibration can offset the alignment and loosen suspension hardware...fix as soon as you can...it may also be an issue with the tires being off balance or an axle being off balance or even the gearing being off balance...check the suspension set up for any flaws and fix those...if the vibration is still present then go with the simplest of solutions and have your tires rebalanced...i noticed a vibration as well that is present at about 55mph in 5th gear and that was simply the tires being off balance....even though they may not show their ugly faces in lower gears or higher rpms they will still show up somewhere on the powertrain band....also look into your steering input shaft maybe even the power steering assist...those can cause problems to as the computer may be compensating for the speed and other factors but controlling it wrong since the car is lowered....good luck

 

When you lower a car you change the driveline angle. Typically with rear wheel drive vehicles the company that designed the lowering kit will supply blocks or wedges to correct the driveline variation. With front wheel drive cars unfortunately there is no simple way to correct the driveline angles. Thats where the vibrations are coming from, the axle shafts at incorrect angles.
