Wats up AZ, so i recentley lowered my car on h&r race springs with stock struts and ever since Ive had this small vibration wen i wud take off from 0 mph. On the highway the car would be riding good til it hits 70mph. At 70mph it would start to vibrate a lil nd da more i speed up da more da vibration would go. Mind you i got 1 inch spacers on the rears only on stock 17 inch wheels. What can this be? Help please. Would really appreciate it. Thanks guys

 

The first 1/2 of your post gave me a headache trying to decipher your spelling, but then you brought it back and had good spelling for the last 1/2 of your post. Funny.

I'd say something is still out of spec under there. I'm not really sure what, but my uneducated guess is that when you installed the new springs, it put something else out of whack in the suspension.

 

LooL yea sorry bout dat i type weird and all the bolts and nuts are on tight and the wheel lug nuts are also tight. Idk why its been vibrating like that. Thats weird

 

Typical things include
Wheels/tires out of balance. Might have lost a wheel weight
Inner CV joint going on axle. Causes vibration primarily on acceleration
LCA bushing going bad can cause vibration
Warped brakes can cause vibration on braking.

Lowering a car can accelerate some of these issues. I'm preparing to change my axles out with a very similar vibration pattern. Maybe this weekend. I have the parts.

 

maybe you hit a pothole and now the wheals arent aligned? happens to my wife like 3 times a week and then she complains that the car is trying to kill her by steering itself into a wall...

 

Maybe it is the alignment. I havent got it aligned since it was dropped, plus the vivration issue began as soon as i drove the car out of the shop meaning before it was lowered it was riding good. Ill go get it aligned and hopefully it was that causing the vibration. Thanks guys
