well earlier i installed a set of Ground-control coilover kit....took it for a ride seems fine at first but when its around 35-40+ mph i feel vibration on my steering wheel thru-out the whole car....any suggestion?

Thanks..

 

you might need an alignment now that the height of the car has changed. Might need to balance the wheels as well. Check to see that everything was tightened properly from the install.

 

yea just get an alignment and balance the corners.
mine doesn't do that though surprisingly, even though i changed my springs.
only reason i need an alignment is because of my camber haha.

 

try out an alignment, then double check any new work.

 

when u put back the wheel did u use torque range? its happens to me when the shop just use the air gun and put on my lug nuts, the steering wheel vibrate when im braking. I found out that i need to torque my wheels.

see if it help =/

 

I doubt it's any of the above guys. I think it's good ol' inboard cv joint problem. This is much more pronounced on older cars like a 2000. The inboard cv splines (don't know what these are called) rub up against the inboard cv housing and etch their way into there. Shown here:



Once you lower your car, it actually moves the position enough so that you're rubbing into a new spot that isn't as worn down. The vibration comes from the inboard cv splines running over that old ridge created by the old position.

I believe there are 3 solutions,
a.) Replace the entire CV Housing with new ones.
b.) Swap the left inner housing for the right inner housing. This solves forward vibration but not backwards vibration.
c.) Axle Spacers, they're sold by a few companies and fairly cheap to come by, depending on the width, it MAY place the splines back into the right position and drive like it used to.

You should get an alignment after changing your suspension.

 

Thanks... guess ima just get a alingnment and see how it turns out... Thanks for the info/suggestion =]

 

Please read around some more I don't want you getting an alignment right away before your suspension/springs have dropped to their normal height only to find out you have to get an alignment done again after. I don' think there's anything in your suspension geometry that would change enough from a simple drop to cause vibrations as bad as you described them.
