I have rattling sound coming from the back of the suspension after i installed the tein flex and edfc?? and the shop that i did the installation said its is normal?? they also said this kit suppose to make sound because it is not stock?? i dought it, can any one give me any advice? Thanks

 

Any advise I can give off tom of my head is to call Tein and find out from them. Good luck, I am looking to do the exactl same setup as yours.

Curious, were these Teins off the shelf or were they ordered directly from Tein? Tein make a running change to the upper sturt mounts to kill noise generated by the dampeners internal valving. Anything that comes directly from Tein will be the new design. One's that are sitting in someone's shelf, could be the old design.
