Under certain driving conditions, owners of TMMC (Canadian built) Lexus RX 330 and RX 350 models may complain of a rattle, vibration or thumping noise from underneath the vehicle. This may be most noticeable at speeds above 40 mph. This applies to 2004-2006 RX 330 and 2007-2008 RX 350 models.
This will require replacement of the fuel tank protector/shield, available as P/N 77641-0E010.
Remove the No. 1 fuel tank shield, secured with four nuts. Install the replacement shield, tightening the four nuts to a value of 49 in.-lbs. (5.5 Nm).
