I own an 05 jetta tdi (older style) and the noise coming from the struts is getting worse. I replaced the front bumpers/bearings on the struts as recommend by the dealer and it seemed to help for a few days. Now after a couple of weeks it is just as loud as before replacement. I torqued the strut nuts again - no difference. The rapping noise is very loud when backing up and is coming from both sides. What am I missing.
