Toyota Motor Sales (TMS), USA is recalling around 760,000 2006 to early 2011 model year RAV4 SUV and abut 18,000 2010 model year Lexus HS 250h hybrid vehicles sold in the US for a rear suspension check.

If nuts on the rear suspension arm are not tightened following the proper procedure and torque specification during a rear wheel alignment service, excessive play may occur at the threaded portion of the arm, followed by rust formation.  If this occurs, the threaded portion of the rear suspension arm may wear and cause the arm to separate, the automaker said.

Toyota is currently developing a repair and will call the vehicles back to dealers when this is available.
