In the Honda Stream RN1 to RN4 the OE front upper spring seats have a specific angular position. Please mark each part before disassembling the original shock absorber (diagram), using the marks to put them back correctly when you install your TEIN springs. If the angular position of an upper spring seat is off, the spring may interfere with the car body and cause noise. The type of noise depends on how far it is off, since it is not perfectly round and its hole is off-centre. Also, it can sound continuously during driving, or only occur when you steer.
