I just bought a 2006 GLS 3.3 Rear end noise is clucky on rough roads..I have seen many complaints on this..Whats the solution..ANYONE !

 

Have you brought this to the attention of your dealer? Have a technician go on a test drive with you and show them the noise.If it is a loud distinctive noise they can connect chassis ears to the vehicle and locate the noise.I cannot tell you what will fix it due to I have not heard the noise. In past I have not had any customer complaints of clunking in rear of vehicle on 06 NF sonata..Note I live where the worst roads you have ever seen are.Bring it to the dealer and let them address it.
