Long-shot but coil bind perhaps???

The bump stops are just fine. It looks like the install was properly done. The more I hear the sounds the more convinced I am the sound is coming from inside. It is coming from both right rear and left rear. I strongly suspect the sound is coming from a inside body panel whacking against the sheet metal due to the way stiffer rear suspension. I am still trying to figure this out. This has had to have happened to someone else!

Something like this happened to me after installing the Tein Basic coilovers....

It turned out that I missed instaling a spacer on the upper rear mounts. So the shocks were not tight against the upper mount and mada a clunk noise over minor bumps.

2" drop is not that much... you can get 2.5" down with the teins...


I would review the installation manual and make sure you got all the parts installed properly. Just because a shop did the job doesn't mean they can not do it wrong.

Yes it was loud.... like the one you describe.

It was a long time ago... and the thread I made when I installed them got lost during the hack.

I was looking for some pics but couldn't find any...


I know for sure that I had to uninstall the rears to fix the problem and it was not clearly visible with the shocks mounted on.

In my case I believe we missed the dust cover. The installation manual was not very clear about it. You were supossed to hacked the OE plastic dust cover and remove the metal top of the cover. This piece worked as a spacer. With out it the shocks were loose and hit the body of the car when driving over bumps.

I attached a copy of the installation manual for the Tein Basics from the tein web site.

Hope you can figure this out.

just got my Tein Basis install this past weekend. I got in to the mission in 8 hours. The rear is like a project. I have to custom cut dust cover and cut the rubber in middle to make a hole install that spacer. Turn around the spring seat top on the bottom and bottom goes to top. Now my vehicle can handle the turn but my tires are not.

The rears should be extremely easy, with no modifications necessary.

Maybe you could post some pictures.

I had done the front is kinda easier than the rear. I purchase all the hard for the front . The upper plate, bearing, dust cover and bump stop. All have to do is put it together. In the rear is kinda difficult cuz i have UR swaybar,Nittor lower trail bar.

The only different I can feel now is less body roll and lower a bit of the vehicle. I drop 1 in the front and 1.5 in the rear. Every time I went over a bump the car feels like lift up to the air. Just wondering is the spring soft or the shock? Also, the tire make more noise now.

Any advice anybody? I got Tein basis. I would like something stiff and not too bumpy.
