Replacement of the Steering Relay Rod on 2wd and 4wd 1990-1995 4Runners.
"If the steering wheel is repeatedly turned under certain conditions where high steering effor is required, for instance when fully turning the wheel while the vehicle is stopped, a fatigue crack may develop in the Steering Relay Rod. In the worst case, the steering relay rod may fracture, causing a loss of vehicle steering control and thus increasing the possibility of a crash."
