Sus Guru's - Steering Wheel Vibrations at 90MPH
 

Just did my springs a few weeks ago and have probably driven the car 3-5 times (about 150 miles) since then. I noticed today that I get some pretty steady vibration throught he steering wheel when I hit about 90. Prior to the spring job she was smooth as glass as high as you wanted to take her.

No, I have not had an alignment done yet.

Is this vibration due to the fact that the springs are stiffer or that the wheels are out of alignment? Perhaps something else?

Suspension guru's: opinions welcome. Howard Coleman, where are you?

Steve

get an alignment, its also possible that your wheels need to be balanced.

if you need someone to do the alignment/balance i can give you the number of a good mechanic in the airpark. he did mine :)

Get those old dry rotted tires replaced steve and then get an alignment. Given the mileage of your car it is very possible they are OE which means they are 10 year old tires. If you still have the problem after that let us know.

Its probably a combination of alignment and balance.

Got some nice 99 wheels w/ tires you want to sell me charles?

Alignments and tires cost money... which is hard to come by these days. I'll tell ya what, I'll give you my 93 stockers for your 99's and $500.

What do you say?

Mike, what did the guy in teh airpark charge you for the alignment?

P.S. Nice quote on the profile. If she knows what a rotary engine is, she's a keeper!

BTW - you get started on the rebuild yet?

If you're cheaping out of an alignment you have no business driving over the speed limit, IMO. Budget for an alignment whenever doing suspension changes. That's all I'll say.

I've not changed springs on an FD, but immediately I would suspect it changes the verticality of the wheels (camber(?)) and if you loosened any of the bolts holding the front suspension in the process you've probably put them back together in a slightly different way, affecting other settings. I know for mcpherson strut suspensions this is true.

hes a friend so he charges me next to nothing, ill give him a call monday and see what he would do for your car.

ha, she only knows what a rotary is cause i cram it down her throat every day :)

and no, the rebuild project should start soon after i get home.
