have a 2000 Jetta (GLS VR6). I got new H&R OE Sport Springs and Bilstein HD shocks. After about 100 miles after installation the springs squeaked (popping noise) when steering (especially noticeable after starting from a stop). Got an alignment and the VW dealer lubed the shocks/spring seats but said due to aftermarket item.....(still makes the popping noise). Any suggestions?
