One problem related to sway bar has been reported for the 1999 Volkswagen Passat. The most recently reported issues are listed below.
07/21/01 scheduled service for clunking/rattling noise in front suspension over small road imperfections and secondly tie rod recall. Mechanic replaced tie rods, but same clunking/rattling noise occurs upon departure. Dealer ordered sway bar links, replaced on second visit. Rattling noise stops, but shortly after repair, sharper clunking resurfaces, turns into also scraping/squeaking noise on sharp turns left with time. Website and independent research indicates many instances of identical symptoms in same model of car leading to possible wheel detachment in extreme circumstances. Other dealers indicate tsbs issued, but no remedy for repair cost on this relatively late model car. Ball joints only come with kit priced at approximately $600 from dealer. After reading numerous website posts, I've become very concerned on safety of car as clunking/knocking/squeaking/scraping noises have grown louder with my vehicle. I'd feel very uncomfortable keeping/selling this car without the problem remedied. I strongly support a vw or at worst case NHTSA initiated recall on this apparent design defect to prevent recurring problems.
