just recently lowered my 430 on coil overs about a month ago. yesterday i notice the steering wheel and front of car would wobble or shake pretty bad. anyone run into this kind of problem before? any help is greatly appreciated! thx!

 

just lowered my ls couple days ago on z40 also but didnt encounter the wobble or shake. first thing to do is alignment. and shaking while driving or braking, or at a stop? shaking while driving=unbalance wheels, defect tires or bent wheels or untorque wheels. shaking while braking=warp rotors/. shaking at a stop=motor or tranny mounts, misfire etc.

 

just did alignment today and wobble/shaking is still there. my next thing to do it rotate the tire front to back and see if that does anything. it happens while drive and i hit a moderate size bump. it feels like that car is wobbling/shaking left and right

 

Maybe it's the steering rack bushings? The first generation SC's had that problem and it was usually the bushings.

 

Heavy wobbles are due to heavy imbalance. Suspension components will not produce these, unless something just torn off.
Alloys, centering of (have you got centering rings?), rubber...

 

What wheels are you running?? you might need hub rings if your running after market wheels I don't have that issue after dropping the car.

 

steering wobble=steering wander rite? if so, a friend of mine had the same problem with his 01 UL after he drop it, he change the tie rods and it fix the problem. his inner is still good so he only change outer tie rods. also i would check all bolts are tighten and torque to spec if possible or hand tighten.

 

thanks i will check that next

 

the wobble is when i go over a bump. car drives smooth, if the road is pretty flat

 

i am running my stock wheels

 

thanks for the tip! i will also be checking all bushings and ball joints. ill let you guys know what i find thx!

 

Steering wheel column.

 

just inspected the front suspension today and found that both my front upper control arm ball joints have up and down play, which im assuming is causing the problem. going to switch it out and see if that fixes it...

 

Keep us updated.

 

hope u found the problems bro
