I recently installed Eibach Pro Kit Springs
TRD Rear Sway
I had 2 new Kumho AST 18in Tires Installed
Alignment was done and everything was within spec

Today driving home from work i noticed this weird thumbing noise coming from the rear of the car. It was hard to produce while driving. It happened at weird times..Once while stopping felt like something was loose. Once while making a turn and going over a slight bump. I can produce it when going up my driveway. It seems like something is loose or rubbing on the sway bar. But I am not sure.

Please help..its killing me not knowing what it is. Click the video below it was taken on my phone might not do any justice.

did check the sturt bolts ?

happy bday dtw

 

you need new shocks.. i had the same noise when i installed the teins you shock is blown.. mine blew out with in 2 weeks..

 

The weird thing is i just test drove it again on the street near my house with a few dips in the road. I hit thos dips going pretty fast and no noises. If the shocks need to be replaced is it bad to drive around with it for awhile...I have no money to replace them at this time

Where are the strut bolts located?

 

the strut bolts are those 4(or 3 forgot haw many are on tc) bolts on top of the strut in your engine bay. if they are loose then that could making the struts loose which is making noise



if your shocks are blown, you'll notice the car being much lower on the side where the shock is blown. there is very little chance of that happening right after you got your springs in.

 

If your shocks are blown, it would be quite a bit bouncy too.

Either loose strut bolts like mentioned or the sway bar connections to the endlinks.

 

I checked both rear sides nothing looks low. The ride doesnt seem bouncy something just feels loose. I am leaning towards loose endlinks? Is this a common thing?

 

That's usually NOT the case, as the shock/strut controls the spring motion, but the spring is what holds the car up and determines it's height.

This is true, as the shock/strut controls the spring's motion.

 

when my shocks blew out the car didnt go any lower and it had that noise like a loosen bolt but when i opened up everything and took one of my shock out i could press that thing all the way in with my bare hands without any pressure.. but double check the bolts first.. open all bolts one by one and tighten it up.. see if that helps..
