Owners of some 2003-07 Lexus GX470 trucks may have difficulty opening the front doors completely. One likely cause, Lexus said, is a damaged or bent door check.
An improved door check is now available to address the problem; Order part No. 68610-60081 for the right side door and part No. 68620-60071 for the left side door.
Begin the fix by removing the inside handle bezel and front armrest from the affected door. Next, remove the power window master switch and the door trim.
Referencing the illustration, remove the door check cover, the two door check attaching nuts, the one attaching bolt and the defective door check.
To complete the repair, install the new-design door check, tighten the attaching nuts and bolt, install the cover, then put the remaining door trim parts back into the vehicle.
