MY CAR IS LOWERED WITH GOLD LINE SPRINGS
I KEEP GETTING A VIBRATION ..SOMETIMES AT LOW SPEED SOME AT HIGH
MY TIRES ARE BALANCED , I HAVE CHANGED RIMS ..
DOES ANY BODY HAVE A CLUE...

 

Vibration.Front?Back? Could it be stuts/shocks? If you're looking for an answer,it helps to have a full description of the problem. We could guess, but I'm sure you really would like some help. P.S.Having the same problem in a Dodge truck and still haven't found it.

 

Lowering a vehicle changes the suspension geometry so you might have a bearing starting to fail due to being loaded differently, or a CV joint starting to go. You have to check the components and work by the process of elimination.

 

I would look at the front hubs....... They seem to be a weak point in the front end. With 60,000 on mine, I have had to change both front hubs. Its a fairly easy job.....

 

Cast and camber is totally different when you lower your ride.
Now what you are doing is you are shoving the trans axles out and into the tranny. The length of the trans axles are MM to long now. It may not seem it , but when you lowered it the Length has to go some where. When you go up and down from stock there is amount of travel for in and out on the axles. Now you lowered it there is no out. Just shove out. Does this make sense to you?

 

no what does shove out mean

 

ok you are pushing the axles out of the bearings in the wheels. Lets say travel of you hhr is 10 inches. 5 up 5 down zero is ride height. you dropped 4" the length of the axles has to go some where. the lenght of the axles has to go out the end or into the transmission. You did not shorten the axles so you are shoving out the bearings on your wheels. On a rw car you can turn the rear axle to make up the difference on the drop that you do, to make up for the extra length of the drive shaft and universal joints. Here you have cvc joints that have little steel balls. I am guessing you length is at least 10 mm to long, that is a guess. Does that make sense to you? You would have to re-size your axles to fit in a shorter space.

 

The axles have about two inches of travel. Goldline springs should put the axles roughly parallel with the ground. I doubt that is the problem.

The OP needs to state if the toe has been adjusted to stock spec and how many times the axles have been replaced.
