after putting my coilovers / struts on, everytime i shift into 2nd going about 20 the steering wheel starts shaking....same thing happens in 3rd in low rpm??? is this just an alignment issue or what else can it be??? thanks

 

Have you replaced axles?

 

make sure your lug nuts are tight

 

Make sure the 3 14mm (might be 12's) nuts that bolt the passenger side axle to the motor are tight.
Make sure all your suspension bolts are tight.
Motor mounts mihgt be getting weak.
Did you get an alignment?

 

i just replaced my axles 2 months ago so i know all the bolts should be tight down there.....no havent gotten an alignment yet...

 

Def an alignment!!!!!! everytime you remove your suspension, its needed!!!

 

Balance your tires. Yah I know doing what you did doesn't change the balance but still perhaps your tires have just now worn enough to require it.

 

Allignment FTW.

 

i sometimes experience this only my car is idle or moving without my foot on the gas pedal
