i just installed sum tein ss 2 weeks ago, and everytime i go over a speed bump, i hear the front suspension making metal clanging sounds, is this because i didnt put the rubber sleeves from the stock springs or improper installation?? Do teins need the rubber sleeves from the stock springs?? thanks

 

if you're talking about the rubber bumper between the top of the spring and the upper spring cup, yes, you need them.

 

im talking about the rubber that wraps around the stock springs to prevent noise

 

you don't need those.
