SEVERE VIBRATION AFTER CHANGING TO TEIN SPRINGS AND KYB SHOCKS/STRUTS

[jedstancill]

I changed to Tein S.Tech springs and KYB GR-2 Shocks and Struts everything went in beautifully. I also had to change a brake line on the right front. I noticed a vibration/wobble in the front on the way home. I have had the 89 240sx realigned and the tire rebalanced; and the vibration/wobble is still there. Please Help??? Any suggestions will be greatly appreciated. Thanks

ball joints, tie rod ends? inner tie rods?

whatever it is, get your money back and slap whoever did the alignment because they should have been able to tell you if it was going to shimmy for any reason.

well since you decided to play engineer no alignment shop has to guarantee that your car can ever be aligned again. Even if your camber, caster, and toe are right it doesnt mean your toe out on turns or steering radius is right. When you move from OEM parts you buy all the problems that come with aftermarket stuff

sorry for your luck

Vibration is usually caused by the wheels, what kind of condition are your tires in?? When was the last time you rotated them.

may sound dumb but i had the same problem once. reason for that was because the lug nuts werent tight. is what i went to myself. lol

true, but I've never seen a competent alignment shop that couldn't clearly tell that something was going to be wrong like that. Whether they garauntee it, fix it, or not, they should be able to tell you if its going to ride relatively smoothly. Any mechanic who's not a complete ignorant d!ck would notice that something wasn't right with it on an alignment machine.

it may be from poor tire installation

[jedstancill]

I had the ball joints, and tie rods including the ends checked and the shop said they were fine. I am however going to be changing the tie rods and ends to tein rods. I will also be installing the tension rods as well.

Do you have any play in any of the wheels? That is, can you grasp them at the top and move them laterally? If so, you may have blown bushings in your hubs. That happened to me on the way to the Winged Warrior event last summer and I thought my damned wheel was going to fall off.

can be the simple stuff making you car wobble

At work we had a shimmy problem that ended up being warped rotors, you dont neccesarily have to feel it in ur brake pedal for it to shimmy. Is there a certin speed it happens at? also like said above check ur wheel for play, check your wheel studs to. I had a hole in my hub that was out of round and it would shake my wheel like crazy.

So I'm stupid eh? I'll remember that...

[nissans13240sx]

No repo, I was just kidding. I value my place here on NICO and wouldn't want to piss you off. I know that a vibration can come from any number of things and I appreciate that you posted just one of many possible problems.

Yep, you are.... sorry.

It's ok. I'll let it slide. This time...

Yep, you are.... sorry.

The vibration/wobble has smoothed some since re-balancing the tires. It is now worse when applying the brakes. I have replaced the wheel studs, rotors, and brakes about 2 months ago. Could it be the one brake line that i changed on the right front??? Thanks for all of the replys.

[ddgsxr504]

A very far fetched idea is that by replacing the brake line it causes that side caliper to work better thus increasing wear causing a vibration???

I still say your tires are cupped or unevenly worn.

I don't mean to jack your thread....but where and for how much did you get your springs and shocks for? I am interested in getting that same combo very soon for my 90 coupe.

[jedstancill]

I got the shocks for around 225 shipped. The springs i got at the local speed shop for 100 dollars. The springs were on another car for about 4 or 5 months and the owner switched to coilovers.

The price is not too shabby.
