I need help. I have been searching through threads but couldn't find a good enough indicator of what it is I'm looking for.

Background: 2009 G37 Sedan, 20x9 front (245/35/20) 20x10 rear (275/30/20), Eibach ProKit Springs, 51,XXX miles, Springs have been on for about 14 days.

After installing the springs, I noticed a clunking noise from the front passenger area, the front driver side is giving no issue, neither are the rears. Everything seems to be intact. My personal diagnostics is a failed strut, strut mount, or bushings need greasing or replacing.

I would like to start by greasing the bushings to make sure that is not the culprit. Anyone have a write up on this or images as to the location of the bushings?

Any advice would greatly be appreciated. If you've had similar problems please let me know what you did to correct this issue.

Thanks in advance

Did you reinstall the triangle gaskets that go under the top strut mounts?

Are both sides the same height from the ground to the fender edge, might have one spring that hasn't settled if the height is off by much.

The bushings are on either side of the upper A arm, also would check sway bar end links, these get under duress when suspensions are altered.

When do you notice this noise? There are cases of coil binding, here's a thread that may be of help there~
Another major problem found with certain lowering springs- coil bind. - Subaru Impreza WRX STI Forums: IWSTI.com

Good Luck, let us know what turns up.

Reinstalled everything correctly. Both sides heights are the same.

Thanks for the info, I will give the bushings and sway bar end links a look as well as look into the thread about 'coil binding'.

FYI: I don't notice the noise at high speeds; excess of 50mph. I notice the noise driving on non smooth roads and driving at speeds -45mph.

I remember when I installed the front springs I had to dig into the rubber covering protection with the spring compressor to be able to install the struts.

If the noise happens when driving on non smooth roads it might be because the coils are hitting.
I would check to make sure the spring has the rubber covering on it.

try tightening the strut bolt. push down on the car with the hood up and look at the strut bolt to see if it's moving.

Good point, should be tightened to 44 ft lbs.

Were the upper control arms tightened in the suspension loaded position?????

If not then the UCA bushings are trying to rotate beyond its range..
